    OPINION
    DUNCAN, Circuit Judge:
    Appellee Antoine Jerome Pettiford pleaded guilty to one
    count of being a felon in possession of a firearm in violation
    of 18 U.S.C. § 922(g), and received an enhanced sentence of
    188 months’ imprisonment, in part because he had five prior
    convictions which qualified him as a career criminal under the
    provisions of the Armed Career Criminal Act (the "ACCA"),
    18 U.S.C. § 924(e). Two of the five state court convictions
    were subsequently vacated, and Pettiford brought a petition
    under 28 U.S.C. § 2255 for post-conviction relief from the
    enhanced federal sentence. The district court granted Petti-
    ford’s petition, holding that as a result of the vacatur of the
    two state convictions, Pettiford was entitled to relief. The dis-
    trict court then resentenced Pettiford to a term of 100 months’
    imprisonment. For the reasons that follow, we reverse the dis-
    trict court’s order and remand with instructions to reinstate
    Pettiford’s original sentence.
    I.
    On November 21, 2002, a grand jury charged Pettiford with
    one count of being a felon in possession of a firearm in viola-
    tion of 18 U.S.C. § 922(g). The grand jury determined that on
    July 4, 2002, Pettiford, "having been convicted of a crime
    punishable by imprisonment for a term exceeding one year,
    did knowingly and unlawfully possess . . . a Smith & Wesson
    .40 caliber semi-automatic pistol." J.A. 11.
    UNITED STATES v. PETTIFORD                   3
    On April 1, 2003, the United States Probation Office issued
    a criminal history report (the "Special Report"), in which it
    considered whether Pettiford was subject to an enhanced
    criminal sentence under the ACCA. The ACCA provides that
    if a person who violates § 922(g) has "three previous convic-
    tions . . . for a violent felony or a serious drug offense, or
    both, committed on occasions different from one another,
    such person shall be fined under this title and imprisoned not
    less than fifteen years." 18 U.S.C. § 924(e)(1). Because Petti-
    ford had eight prior violent and serious drug felonies, the
    United States Probation Office concluded that he qualified for
    an enhanced sentence under the ACCA.
    In a May 28, 2003, letter, Pettiford contested the validity of
    three of the eight convictions as ACCA predicates, and the
    Special Report was revised to eliminate them on July 9, 2003.
    Thereafter, on October 6, 2003, the government filed a
    Notice/Information of Enhanced Penalties, in which it
    explained that Pettiford was subject to the enhanced penalty
    provisions of § 924(e)(1), based in part on the following five
    state convictions: (1) a 1993 conviction for possession with
    intent to manufacture narcotics; (2) a 1994 conviction for
    breaking and entering a dwelling, battery, malicious destruc-
    tion, and assault; (3) a 2001 conviction for second-degree
    assault; (4) a 2002 conviction for possession with intent to
    distribute cocaine; and (5) a 2002 conviction for conspiracy
    to distribute and possession with intent to distribute cocaine.
    Pursuant to a written plea agreement, signed on January 16,
    2004, Pettiford pleaded guilty to the charged offense. In that
    agreement, Pettiford stipulated that he was "an Armed Career
    Criminal subject to an enhanced sentence under the provisions
    of 18 U.S.C. § 924(e)." J.A. 18. He further stipulated that
    based on the Notice/Information of Enhanced Penal-
    ties filed by the United States on October 6, 2003,
    and as found by the U.S. Probation Office in its pre-
    trial criminal history report, Mr. Pettiford has three
    4                     UNITED STATES v. PETTIFORD
    or more prior convictions which qualify him as a
    Armed Career Criminal subject to an enhanced sen-
    tence under the provisions of 18 U.S.C. § 924(e).
    J.A. 19. The district court confirmed that Pettiford agreed that
    he was subject to an ACCA enhanced sentence in its plea col-
    loquy, and again at sentencing.1 Thereafter, the district court
    sentenced Pettiford to 188 months’ imprisonment, and Petti-
    ford did not appeal this sentence.
    Before sentencing, Pettiford filed in state court a coram
    nobis petition for post-conviction relief, seeking to vacate his
    two 2002 convictions. On September 7, 2004, after Pettiford
    had been sentenced in federal court, the Circuit Court for Bal-
    timore County vacated the two 2002 convictions, concluding
    that the sentences had been illegal because the court imposed
    an invalid period of incarceration as a condition of probation.
    Almost a year later, on August 15, 2005, Pettiford filed a peti-
    tion under 28 U.S.C. § 2255 for post-conviction relief from
    the enhanced federal sentence in the District Court of Mary-
    land.
    In his pro se § 2255 petition, Pettiford contended that he
    was entitled to relief because as a result of the vacatur of the
    two 2002 drug convictions, he no longer qualified as an
    armed career criminal. Specifically, he argued that his 1993
    1
    At sentencing, Pettiford’s counsel suggested that Pettiford’s 1993 con-
    viction for possession with intent to manufacture narcotics might not count
    as an ACCA predicate offense because he thought that under Maryland
    law the maximum sentence for conspiracy to distribute cocaine was five
    years, which would not meet the threshold for a "serious offense" under
    18 U.S.C. § 924(e)(2)(A)(ii). Counsel, however, later retracted that sug-
    gestion, noting that he "had someone check and ask around, and it appears
    that in fact the maximum penalty may actually [have] been 20 years, . . .
    not five." J.A. 82. The district court did not consider this issue because
    Pettiford’s counsel, upon further inquiry, explained that resolution of this
    issue was irrelevant to his client’s ultimate designation as an armed career
    criminal in light of Pettiford’s four other qualifying convictions.
    UNITED STATES v. PETTIFORD                         5
    drug conviction could not have been an ACCA predicate con-
    viction because, he alleged, "the judgment and transcript do
    not show whether [he] was convicted of conspiracy to possess
    with intent to distribute a controlled substance or conspiracy
    to merely possess a controlled substance (which [was] Mr.
    Pettiford’s recollection)." J.A. 193. Because his 1993 drug
    conspiracy conviction was merely a possession offense, Petti-
    ford maintained that he had only two remaining convictions
    that qualified for ACCA purposes, not three.
    On January 11, 2007, the district court issued an order
    appointing a Public Defender to represent Pettiford, and
    requiring the Public Defender to verify whether, in addition
    to the 1993 conviction, Pettiford wished to challenge any of
    the other non-vacated qualifying convictions. In response to
    this order, on June 15, 2007, the Public Defender filed a mem-
    orandum of law explaining that Pettiford challenged the use
    of all his predicate convictions. The government filed a
    response to this memorandum on July 6, 2007, arguing, inter
    alia, that Pettiford was procedurally barred from challenging
    the use of the three predicate convictions because these chal-
    lenges "were not raised at trial or on direct appeal, and the
    defendant neither offer[ed] cause excusing this failure nor
    c[ould] he show prejudice from not having raised the argu-
    ments." J.A. 232. As a result, in a reply, the Public Defender
    clarified that for § 2255 purposes, only the two 2002 vacated
    convictions should be considered, and that Pettiford’s chal-
    lenges to the three remaining predicates were "not [a] part of
    his habeas petition [but] instead[ ] they [were] relevant con-
    siderations at a resentencing following the grant of his habeas
    petition."2 J.A. 250. In other words, Pettiford asked the district
    court to bifurcate the proceedings.
    On November 24, 2008, the district court granted Petti-
    2
    Later, Pettiford conceded that the 1993 conspiracy conviction qualified
    as an ACCA predicate. Thus, Pettiford maintained that only the 1994 and
    2001 convictions were to be considered at resentencing.
    6                 UNITED STATES v. PETTIFORD
    ford’s § 2255 petition and ordered that he be resentenced. The
    district court granted Pettiford habeas relief because "two of
    his qualifying convictions [had been] vacated after his initial
    sentence." J.A. 263. The district court recognized that even
    with the two 2002 drug convictions vacated, Pettiford’s
    record "retain[ed] three convictions that might enhance his
    sentence under § 924(e)," J.A. 266, but nevertheless granted
    Pettiford a resentencing based on an "examination of [Petti-
    ford’s] remaining ACCA qualifying convictions . . . akin to
    what would occur at a re-sentencing proceeding," J.A. 267. In
    doing so, the district court decided that Pettiford’s conviction
    for Maryland assault in 2001 was not a violent felony under
    the ACCA. Relying on Shepard v. United States, 
    544 U.S. 13
    (2005), and United States v. Simms, 
    441 F.3d 313
    (4th Cir.
    2006), the district court explained that when analyzing
    whether a conviction is a violent felony under the ACCA,
    courts cannot consider documents "that are not incorporated
    into the charging document." J.A. 269. Because the only basis
    for concluding that Pettiford’s 2001 assault might be a violent
    felony is found in a Statement of Probable Cause, which was
    not incorporated into the charging document, the district court
    concluded that the 2001 assault conviction was not a violent
    felony, and thus could not be counted. Disregarding both the
    2001 assault conviction and the two sentences vacated by the
    Maryland state courts, the district court found "that Pettiford
    has two remaining ACCA qualifying convictions . . . [and] no
    longer qualifies" for an enhanced sentence under the ACCA.
    J.A. 270.
    On December 8, 2008, the government filed a motion for
    reconsideration, which the district court denied on January 7,
    2009. Pettiford was subsequently resentenced on January 8,
    2009 to 100 months in prison. This appeal followed.
    II.
    On appeal, the government contends that the district court
    erred in granting Pettiford’s § 2255 petition, because even
    UNITED STATES v. PETTIFORD                            7
    after the vacatur of Pettiford’s two drug convictions, Pettiford
    still had three qualifying predicate convictions. Pettiford
    responds that a defendant need only show that some of his
    underlying predicate convictions were vacated to be entitled
    to § 2255 relief. However, in the event we find otherwise, he
    argues that his challenges to the other predicate convictions
    should be considered as part of his habeas claim, and that if
    he failed to challenge these convictions, that failure should be
    excused because he can show cause and prejudice for the pro-
    cedural default. Alternatively, he maintains he is "actually
    innocent of the enhancement," and thus, the district court did
    not commit error in granting the petition. Appellee’s Br. at 15.
    We consider each argument in turn. In so doing, we review
    legal issues de novo and factual findings under a clear error
    standard. United States v. Roane, 
    378 F.3d 382
    , 395 (4th Cir.
    2004).
    A.
    We first consider the government’s argument that the dis-
    trict court erred in granting Pettiford’s § 2255 petition on the
    basis of Pettiford’s two vacated convictions.3
    3
    Pettiford’s § 2255 petition maintained that he was entitled to habeas
    relief solely because two of his five ACCA-predicate convictions had been
    vacated. Admittedly, in his initial § 2255 petition, Pettiford did challenge
    the predicate status of his 1993 drug conviction. Later, however, he clari-
    fied that for § 2255 purposes only the two 2002 vacated convictions
    should be considered, and that his "challenges to the three remaining pred-
    icates [were simply] re-sentencing issues." J.A. 259. The district court
    accepted this clarification, explaining that "Pettiford’s challenge to [the
    remaining] convictions" were not "a part of his § 2255 petition." J.A. 267.
    Instead, the court’s "examination of his remaining ACCA qualifying con-
    victions [was] akin to what would occur at a re-sentencing proceeding,"
    after § 2255 relief was granted. J.A. 267. Thus, in considering whether to
    grant Pettiford’s § 2255 petition to begin with, the district court considered
    only whether Pettiford was entitled to relief as a result of the vacatur of
    his two state convictions.
    8                    UNITED STATES v. PETTIFORD
    In Custis v. United States, 
    511 U.S. 485
    , 497 (1994), the
    Supreme Court observed that if a defendant "is successful in
    attacking [his] state sentences, he may then apply for reopen-
    ing of any federal sentence enhanced by the state sentences."
    Later, in Daniels v. United States, 
    532 U.S. 374
    , 382 (2001),
    the Court again noted that if a challenge to an underlying con-
    viction is successful in state court, "the defendant may then
    apply for reopening of his federal sentence," but added that if
    the prior conviction is no longer open to direct or collateral
    attack in its own right, then the federal prisoner can do noth-
    ing more about his sentence enhancement. Finally, in Johnson
    v. United States, 
    544 U.S. 295
    , 310 (2005), the Court reiter-
    ated the holdings of Custis and Daniels, adding, inter alia, that
    from the date the district court enters judgment in the federal
    case, the defendant is obliged to act diligently to obtain the
    state-court order vacating the predicate conviction.
    In accordance with this line of cases, this court, when
    reviewing sentences imposed under the career offender guide-
    line, has concluded that sentence enhancements based on pre-
    vious convictions should be reconsidered if those convictions
    are later vacated. See United States v. Gadsen, 
    332 F.3d 224
    ,
    228 (4th Cir. 2003) (noting that a defendant may apply for a
    reopening of his federal sentence once he has successfully
    challenged the underlying conviction).4 Specifically, this court
    has held that if a defendant "succeeds in a future collateral
    proceeding in overturning his [state] conviction, federal law
    enables him then to seek review of any federal sentence that
    was enhanced due to his state conviction." United States v.
    Bacon, 
    94 F.3d 158
    , 161 n.3 (4th Cir. 1996). Given this lan-
    guage, the district court determined that Pettiford was entitled
    4
    Custis, Daniels, and Johnson apply "whether the sentence enhance-
    ment was imposed because of the ACCA or because of the Sentencing
    Guidelines." 
    Gadsen, 332 F.3d at 228
    n.3 (internal quotations and citation
    omitted); see also United States v. Arango-Montoya, 
    61 F.3d 1331
    , 1336
    (7th Cir. 1995); United States v. Jones, 
    27 F.3d 50
    , 52 (2d Cir. 1994) (per
    curiam); United States v. Garcia, 
    42 F.3d 573
    , 581 (10th Cir. 1994).
    UNITED STATES v. PETTIFORD                        9
    to § 2255 relief because he had successfully challenged in
    state court two state sentences that had been used to enhance
    his federal sentence.
    However, as noted by the government, even without the
    two vacated state convictions, Pettiford’s record retains three
    convictions that support enhancing his sentence under
    § 924(e). Thus, the issue before us is whether a petitioner is
    entitled to § 2255 relief after successfully attacking some of
    his predicate sentences if those vacated convictions are not
    necessary for the armed career criminal designation. Neither
    we nor the Supreme Court have addressed this specific issue.5
    And although, since Custis, several other circuits have held or
    indicated that a defendant may be able to receive § 2255 relief
    if he has successfully challenged in state court a state convic-
    tion previously used in enhancing the federal sentence, in
    each of these cases, the state sentences at issue, if vacated,
    would have lowered the defendant’s conviction count below
    the minimum number necessary to enhance the sentence. See,
    e.g., United States v. Doe, 
    239 F.3d 473
    , 475 (2d Cir. 2001);
    United States v. LaValle, 
    175 F.3d 1106
    , 1108 (9th Cir.
    1999); United States v. Walker, 
    198 F.3d 811
    , 813 (11th Cir.
    1999); United States v. Pettiford, 
    101 F.3d 199
    , 200 (1st Cir.
    1996); Young v. Vaughn, 
    83 F.3d 72
    , 73 (3d Cir. 1996);
    United States v. Cox, 
    83 F.3d 336
    , 339 (10th Cir. 1996);
    United States v. Rogers, 
    45 F.3d 1141
    , 1143 (7th Cir. 1995);
    United States v. Nichols, 
    30 F.3d 35
    , 36 (5th Cir. 1994).
    To determine whether Pettiford should have been awarded
    habeas relief and had his sentence reopened on the ground
    that two of the five convictions used to support his sentence
    5
    Custis, Daniels, and Johnson all dealt with defendants whose enhanced
    sentences might have been materially impacted by the vacatur of the chal-
    lenged state convictions. See 
    Custis, 511 U.S. at 497
    (attacking two of
    three predicate convictions); 
    Daniels, 532 U.S. at 374
    (attacking two of
    four predicate convictions); 
    Johnson, 544 U.S. at 295
    (attacking one of
    two predicate convictions).
    10                 UNITED STATES v. PETTIFORD
    were later vacated, we must look to the language of 28 U.S.C.
    § 2255. Section 2255 provides that habeas relief should be
    awarded where
    the court finds that the judgment was rendered with-
    out jurisdiction, or that the sentence imposed was not
    authorized by law or otherwise open to collateral
    attack, or that there has been such a denial or
    infringement of the constitutional rights of the pris-
    oner as to render the judgment vulnerable to collat-
    eral attack.
    28 U.S.C. § 2255(b). Once the petitioner has shown this, "the
    court shall vacate and set the judgment aside and shall dis-
    charge the prisoner or resentence him or grant a new trial or
    correct the sentence as may appear appropriate." 
    Id. Thus, a
    district court’s resolution of a prisoner’s § 2255 petition pro-
    ceeds in two steps. See United States v. Hadden, 
    475 F.3d 652
    , 661 (4th Cir. 2007). First, the district court must deter-
    mine whether the prisoner has met his burden of showing that
    his sentence is unlawful on one of the specified grounds. 
    Id. Second, if
    the prisoner’s sentence is found unlawful on one of
    those grounds, the district court should grant the prisoner an
    "appropriate" remedy, which includes discharge, resentenc-
    ing, or a new trial. 
    Id. If the
    prisoner fails to show that his
    sentence is unlawful on one of the specified grounds under the
    threshold inquiry, however, "the court must deny the peti-
    tion." 
    Id. Pettiford cannot
    meet the threshold inquiry, in that he has
    failed to establish any of the specified grounds for rendering
    the sentence unlawful. First, he cites no precedent, nor do we
    find any, suggesting that, in this situation, Pettiford was sen-
    tenced in violation of the Constitution. Second, he points to
    nothing in the record, nor are we able to find anything, to sug-
    gest that the district court did not have jurisdiction. Third, the
    sentence was authorized by law because the vacatur of the
    two 2002 convictions did not render Pettiford’s ACCA sen-
    UNITED STATES v. PETTIFORD                   11
    tence invalid as a threshold matter. Section 924(e)(1) estab-
    lishes a mandatory minimum sentence of fifteen years without
    parole for any person convicted of a violation of 18 U.S.C.
    § 922(g) who has three or more previous convictions for a
    "violent felony" or "serious drug offense." 18 U.S.C.
    § 924(e)(1). After the vacatur of the two 2002 convictions,
    three predicate convictions remained in Pettiford’s record.
    Thus, the statutory preconditions for sentence enhancement
    were still present, and Pettiford’s sentence was still subject to
    enhancement pursuant to the ACCA. Finally, we do not
    believe that the sentence is "otherwise open to collateral
    attack." 28 U.S.C. § 2255(a). The Supreme Court has inter-
    preted the phrase "otherwise subject to collateral attack" as
    involving a claim of "error of fact or law of the ‘fundamental’
    character that renders the entire proceeding irregular and
    invalid." United States v. Addonizio, 
    442 U.S. 178
    , 186
    (1979); see also United States v. Eakman, 
    378 F.3d 294
    , 298
    (3d Cir. 2004) (holding that a sentence is subject to collateral
    attack if "the district court received ‘misinformation of a con-
    stitutional magnitude’ and . . . the district judge relied at least
    in part on that misinformation" (quoting United States v.
    Spiropoulos, 
    976 F.2d 155
    , 163 (3d Cir. 1992)). There is no
    evidence that Pettiford’s sentencing was constitutionally
    defective or flawed in a fundamental way. Indeed, in his
    habeas petition, Pettiford made no such claim.
    Instead of finding that Pettiford’s sentence was unlawful on
    one of the specified grounds, the district court granted Petti-
    ford § 2255 relief on the assumption that vacatur of any predi-
    cate sentence automatically entitles a petitioner to habeas
    relief without further inquiry. See J.A. 266 ("[T]his Court . . .
    finds that Pettiford’s subsequently vacated convictions entitle
    him to a re-sentencing."). This was error. Vacatur alone does
    not entitle a petitioner to habeas relief. Rather, as we stated
    in Bacon, vacatur entitles a petitioner to "seek 
    review." 94 F.3d at 162
    n.3. In seeking review, however, the petitioner
    must still meet his burden of showing that his sentence is
    unlawful on one of the specified grounds, because only after
    12                    UNITED STATES v. PETTIFORD
    determining that a sentence is unlawful can the district court
    vacate and set aside the sentence. See 
    Hadden, 475 F.3d at 661
    . Here, not only did Pettiford fail to show that his sentence
    was rendered unlawful by the vacatur of his two 2002 convic-
    tions, but also the district court failed to make this inquiry
    before finding that Pettiford was entitled to § 2255 relief.
    Admittedly, after granting § 2255 relief, the district court
    did determine that Pettiford’s sentence was unlawful. After
    concluding that "Pettiford’s subsequently vacated convictions
    entitle[d] him to [habeas relief]," J.A. 266, the district court
    considered Pettiford’s remaining ACCA qualifying convic-
    tions "akin to what would occur at a re-sentencing proceed-
    ing," J.A. 267, and determined that without his 2001 assault
    conviction, Pettiford’s sentence exceeded the maximum sen-
    tence allowed by law because the sentence could no longer be
    enhanced under the ACCA.6 In so doing, however, the district
    court inverted the § 2255 process. Pursuant to Hadden, the
    district court had to determine whether Pettiford’s sentence
    had been rendered unlawful on one of the specified grounds
    by the vacatur of his two 2002 convictions before vacating
    and setting aside the sentence. 
    See 475 F.3d at 661
    . By doing
    otherwise, the district court bypassed the threshold inquiry of
    whether Pettiford’s § 2255 petition, on its face, sufficiently
    established that Pettiford’s sentence was "rendered without
    jurisdiction," "imposed in violation of the Constitution or the
    laws of the United States," or that it was "otherwise subject
    to collateral attack." 28 U.S.C. § 2255.
    6
    The government argues that the district court committed error in allow-
    ing Pettiford, after the court granted him § 2255 relief but before fashion-
    ing a remedy, to argue that his remaining ACCA qualifying convictions
    were not predicate offenses under the ACCA. The district court reasoned
    that irrespective of whether these challenges are procedurally barred,
    "[t]he more efficient rule is to permit defendants to raise such arguments
    after they have had other convictions vacated and the arguments could
    have an actual impact on their sentences." J.A. 267. Because we find that
    the district court erred in granting Pettiford’s § 2255 motion, we need not
    decide whether the district court’s consideration of these challenges, in
    order to determine Pettiford’s appropriate remedy, constitutes error.
    UNITED STATES v. PETTIFORD                           13
    The flaw in the district court’s approach is made manifest
    by the fact that, by virtue of the vacated convictions, Pettiford
    argued on collateral review the applicability of case law that
    would not be available to others similarly situated. Below,
    Pettiford argued that his 2001 assault conviction could not be
    counted as an ACCA predicate because it was not a violent
    felony. His argument principally relied on 
    Shepard, 544 U.S. at 21
    , in which the Supreme Court held that to determine
    whether a conviction constitutes a violent felony, a court may
    not go "beyond conclusive records made or used in adjudicat-
    ing guilt and look[ ] to documents submitted to lower courts
    even prior to charges," and on 
    Simms, 441 F.3d at 317
    , in
    which we held that a court may not consider documents that
    are not "expressly incorporated into [the] charging docu-
    ment." Relying on these cases, Pettiford argued that his 2001
    assault could not be classified as a violent felony because the
    only basis for such a conclusion is found in a Statement of
    Probable Cause which was not incorporated into the charging
    document. The district court agreed with Pettiford, citing
    Shephard and Simms for support. Neither Shepard nor Simms,
    however, were available to Pettiford at the time of the original
    sentencing, nor have they been found to be retroactively
    applicable. See United States v. Davis, 133 F. App’x 916 (4th
    Cir. 2005); see also United States v. Christensen, 
    456 F.3d 1205
    , 1207-08 (10th Cir. 2006); Corey v. United States, 221
    F. App’x 1 (1st Cir. 2007); United States v. Armstrong, 151
    F. App’x 155, 157 (3d Cir. 2005). And, as we have noted, the
    district court reached this inquiry only because it bypassed the
    threshold determination of whether Pettiford’s § 2255 peti-
    tion, on its face, sufficiently established that Pettiford’s sen-
    tence was unlawful on one of the specified grounds.7
    7
    Furthermore, the district court’s actions effectively allowed Pettiford to
    raise challenges that were procedurally barred. Pettiford could have chal-
    lenged the adequacy of classifying his 1993, 1994, and 2001 convictions
    as ACCA predicates at the original sentencing and on direct appeal, and
    because he did not do so, those challenges are barred unless Pettiford can
    "show cause and actual prejudice . . . or . . . that a miscarriage of justice
    14                    UNITED STATES v. PETTIFORD
    In sum, because the district court failed to hold Pettiford to
    his burden of showing that the vacated sentences rendered his
    federal sentence unlawful on one of the specified grounds—a
    burden the record demonstrates he could not meet—we agree
    with the government that the district court erred in granting
    Pettiford § 2255 relief.8
    B.
    Although Pettiford characterized his challenges to the
    remaining three convictions as resentencing issues in the dis-
    trict court, on appeal, he argues that we should consider his
    challenges to the 1994 and 2001 predicate convictions as part
    of his habeas petition. If we do so, he asserts that we should
    find him entitled to § 2255 relief. Because Pettiford never
    challenged his three remaining predicate convictions at sen-
    tencing or on direct appeal, he would typically be "barred
    from raising the[se] claim[s] on collateral review." Sanchez-
    Llamas v. Oregon, 
    548 U.S. 331
    , 351 (2006); see also United
    States v. Emanuel, 
    869 F.2d 795
    , 796 (4th Cir. 1989) (non-
    constitutional issues are deemed waived in a § 2255 motion
    would result from the refusal of the court to entertain the collateral attack."
    United States v. Mikalajunas, 
    186 F.3d 490
    , 492-93 (4th Cir. 1999). Petti-
    ford, however, was not required to show cause and prejudice or a miscar-
    riage of justice because the district court accepted Pettiford’s argument
    that his challenges were to be considered after the court granted him
    § 2255 relief. Effectively, the district court allowed Pettiford to forego the
    burden of showing cause and prejudice or a miscarriage of justice, but
    nevertheless considered Pettiford’s attacks on his 1994 and 2001 convic-
    tions to determine that his sentence was unlawful. The entire § 2255 pro-
    cess was therefore turned on its head.
    8
    The government also argues that should we find that the district court
    properly granted Pettiford § 2255 relief, then we must find error in the dis-
    trict court’s willingness to allow Pettiford to "revise unilaterally the terms
    of his plea agreement," in which he affirmed, more than once, that he was
    subject to an ACCA sentence. Appellant’s Br. at 27. Because we find the
    district court erred in granting Pettiford’s § 2255 petition, we need not
    address the binding effect of Pettiford’s plea agreement.
    UNITED STATES v. PETTIFORD                         15
    if they were not raised on direct appeal). The Supreme Court
    has recognized an equitable exception to the bar, however,
    when a habeas applicant can demonstrate cause and prejudice,
    or actual innocence. See Dretke v. Haley, 
    541 U.S. 386
    , 393
    (2004); see also 
    Mikalajunas, 186 F.3d at 492-93
    . We thus
    consider whether Pettiford has shown cause and prejudice, or
    actual innocence, below.
    1.
    "In order to collaterally attack a conviction or sentence
    based upon errors that could have been but were not pursued
    on direct appeal, the movant must show cause and actual prej-
    udice resulting from the errors of which he complains . . . ."
    
    Mikalajunas, 186 F.3d at 492-93
    . "The existence of cause for
    a procedural default must turn on something external to the
    defense, such as the novelty of the claim or a denial of effec-
    tive assistance of counsel." 
    Id. at 493.
    Pettiford maintains that cause existed to excuse his default
    because he had no legal basis to challenge the predicate con-
    victions at the original sentencing.9 He explains that at the ini-
    tial sentencing, his two 2002 drug convictions had not yet
    been vacated, and in the absence of these reversals, he still
    had three prior serious drug offenses—the two 2002 drug con-
    victions and the 1993 drug conspiracy conviction—on his
    record to qualify him as an armed career criminal independent
    from the 2001 assault conviction and the 1994 breaking and
    entering conviction. As a result, he argues, any challenge to
    his ACCA status, or the underlying sentences, at his original
    sentencing would have been futile.
    9
    Pettiford also explains that the prejudice suffered here is obvious. The
    ACCA enhancement increased his statutory maximum penalty from ten to
    fifteen years, and his sentencing guideline range from 84-105 months to
    188-235 months. Because we find that Pettiford cannot show cause, we
    need not determine whether Pettiford has shown sufficient prejudice. See,
    e.g., 
    Mikalajunas, 186 F.3d at 493-94
    (discussing only the element of
    cause). The exception requires a showing of both cause and prejudice.
    16                UNITED STATES v. PETTIFORD
    As a preliminary matter, the government asserts, and our
    review of the record reveals, that Pettiford never argued cause
    and prejudice below. Instead, Pettiford maintained that his
    challenges to the 1994 and 2001 convictions were resentenc-
    ing issues, not habeas issues, and thus he was able to forego
    showing cause and prejudice. In the briefs below, Pettiford’s
    counsel explained, "[T]he challenges to Mr. Pettiford’s other
    prior convictions are not part of his habeas petition. . . . Mr.
    Pettiford has not sought to amend his habeas petition to
    include these challenges." J.A. 250-51. Similarly, counsel
    maintained, "[T]he criminal history challenges to the three
    remaining predicates are re-sentencing issues, not habeas
    claims." J.A. 259. It is settled in this circuit that failure to
    present an argument to the district court constitutes waiver
    before this court. United States v. Evans, 
    404 F.3d 227
    , 236
    n.5 (4th Cir. 2005). Further, the Supreme Court recently held
    that an argument not presented to the federal district court in
    a habeas petition is forfeited and cannot be advanced at the
    merits stage, on appeal. McDaniel v. Brown, 
    130 S. Ct. 665
    ,
    675 (2010) ("Recognizing that his . . . claim cannot prevail,
    respondent tries to rewrite his federal habeas petition. His
    attempt comes too late, however, and he cannot now start
    over.").
    Nonetheless, assuming arguendo that Pettiford’s current
    "cause" theory is properly before us, we are unable to find any
    external impediments resulting in counsel’s failure to chal-
    lenge the 1994 and 2001 convictions at sentencing, or on
    direct appeal. On the contrary, the record shows that trial
    counsel did challenge three of the eight predicate convictions
    listed on the Special Report. "[A] petitioner cannot establish
    cause when the facts underlying the claim were in existence
    and were available upon a reasonably diligent search," Rose
    v. Lee, 
    252 F.3d 676
    , 687 (4th Cir. 2001), and here, the facts
    underlying Pettiford’s challenges to the 1994 and 2001 con-
    victions were available at Pettiford’s sentencing.
    UNITED STATES v. PETTIFORD                          17
    Further, Pettiford’s alleged basis for demonstrating cause
    has no recognition in the law.10 See, e.g., Bousley v. United
    States, 
    523 U.S. 614
    , 623 (1998) (finding that "futility cannot
    constitute cause if it means simply that a claim was unaccept-
    able to that particular court at that particular time" (internal
    quotations and citation omitted)); Richardson v. Turner, 
    716 F.2d 1059
    , 1061 (4th Cir. 1983) (holding the same). If we
    were to accept Pettiford’s argument—that cause exists to
    excuse procedural default where the defendant believes that
    challenging a predicate sentence would be futile—then there
    would be no reason for a defendant to challenge his predicate
    convictions during sentencing, unless he could attack a suffi-
    cient number of sentences to bring his predicate count below
    the number necessary for the enhancement. All other chal-
    lenges would be handled by the courts on collateral attack,
    thereby rendering meaningless our longstanding commitment
    to the finality of judgments. See, e.g., Sawyer v. Whitley, 
    505 U.S. 333
    , 338 (1992) (emphasizing finality over the correc-
    tion of errors); McCleskey v. Zant, 
    499 U.S. 467
    , 490-91
    (1991) (same); Wainwright v. Sykes, 
    433 U.S. 72
    , 89-90
    (1977) (same). We cannot agree to this. Habeas review
    extracts significant costs from judicial, defense, and prosecu-
    torial resources. Schneckloth v. Bustamonte, 
    412 U.S. 218
    ,
    259-60 (1973) (Powell, J., concurring). More importantly, as
    the Supreme Court said in McCleskey, we do not want "ha-
    beas corpus review [to] give litigants incentives to withhold
    claims for manipulative purposes and [to] establish disincen-
    tives to present claims when evidence is 
    fresh." 499 U.S. at 491-92
    ; see also Reed v. Ross, 
    468 U.S. 1
    , 13 (1984); Wain-
    
    wright, 433 U.S. at 89
    . Instead, if an attack on a predicate sen-
    tence can be raised at sentencing, that attack should be han-
    dled by the sentencing judge, irrespective of whether a
    successful challenge would render a sentencing enhancement
    obsolete.
    10
    Nor is it clear why it would have been futile for Pettiford to challenge
    the 1994 and 2001 convictions at sentencing or on direct appeal. Pettiford
    filed the coram nobis petition for post-conviction relief, seeking to vacate
    his two 2002 convictions, before his original sentencing took place.
    18                UNITED STATES v. PETTIFORD
    Thus, because we find that Pettiford has failed to demon-
    strate cause to excuse his failure to challenge the 1994 and
    2001 predicate sentences at sentencing or on direct appeal, we
    cannot excuse his procedural default.
    2.
    With Pettiford having failed to demonstrate cause and prej-
    udice to excuse his procedural default, the question remains
    whether he can show actual innocence. Pettiford contends that
    he should be granted habeas relief because he is "actually
    innocent of the enhancement," Appellee’s Br. at 15, in that his
    record does not have "three previous convictions . . . for a vio-
    lent felony or a serious drug offense," 18 U.S.C. § 924(e)(1).
    Aside from the two vacated convictions, he notes that his
    2001 assault conviction could not be considered a "violent fel-
    ony" for ACCA purposes, and thus, he contends, the basis for
    the district court’s original ACCA finding vanished because
    three ACCA predicates no longer remain.
    Our court has previously ruled that the actual innocence
    exception may be applied in § 2255 to noncapital sentencing
    proceedings. United States v. Maybeck, 
    23 F.3d 888
    , 892-94
    (4th Cir. 1994); see also 
    Mikalajunas, 186 F.3d at 494
    . To
    succeed on actual innocence grounds, however, "a petitioner
    must demonstrate actual factual innocence of the offense of
    conviction, i.e., that petitioner did not commit the crime of
    which he was convicted; this standard is not satisfied by a
    showing that a petitioner is legally, but not factually, inno-
    cent." Mikalajunas, 
    186 F.3d 494
    . Furthermore, the "movant
    must show actual innocence by clear and convincing evi-
    dence." 
    Id. at 493.
    Pettiford’s argument on this point suffers from multiple
    infirmities. To begin with, a federal sentencing proceeding is
    not ordinarily an appropriate forum in which to challenge the
    validity of a prior state conviction. Whether petitioner is actu-
    ally innocent of a prior state offense is a claim to be tested
    UNITED STATES v. PETTIFORD                            19
    through the normal processes of trial and appeal and any
    appropriate post-conviction proceedings. A federal sentencing
    court cannot be expected to hold a re-trial of prior state con-
    victions, and even if the resources to do so were available, a
    respect for state courts would dictate that the validity of state
    convictions be resolved not in federal sentencing proceedings
    but in the manner that Congress and the Supreme Court have
    set forth. We earlier noted that the Supreme Court in a trio of
    cases has counseled against using federal sentencing proceed-
    ings as a forum for collateral attacks on state convictions. See
    
    Johnson, 544 U.S. at 303
    (Congress did not intend "to make
    it so easy to challenge final judgments that every occasion to
    enhance a sentence for recidivism would turn a federal sen-
    tencing court into a forum for difficult and time-consuming
    reexaminations of stale state proceedings."); 
    Daniels, 532 U.S. at 381-82
    ; 
    Custis, 511 U.S. at 496-97
    . In this regard, any
    argument of actual factual innocence of the remaining convic-
    tions has not been accepted by any court or in any forum in
    which Pettiford could be expected to move to set the convic-
    tion aside.
    Pettiford further misinterprets our holdings in Mikalajunas
    and Maybeck. Irrespective of our holding in Mikalajunas, Pet-
    tiford maintains that for purposes of proving actual innocence
    in the context of eligibility for application of the ACCA,
    Fourth Circuit precedent requires only that he show that the
    district court erred in applying the statute. His argument prin-
    cipally relies on our holding in Maybeck. In that case, the
    defendant was originally sentenced as a career offender under
    the Sentencing Guidelines based on two prior convictions
    noted in the presentence report as crimes of violence.11 The
    11
    We recognize that Maybeck concerns the career offender provision of
    the Sentencing Guidelines, and not the ACCA. Nevertheless, in Mikala-
    junas, we noted that under the reasoning of Maybeck, "actual innocence
    applies in . . . the context of eligibility for application of a career offender
    or other habitual offender . . . 
    provision." 186 F.3d at 495
    (emphasis
    added). To reach its holding, Maybeck relied on cases concerning various
    20                   UNITED STATES v. PETTIFORD
    defendant did not object to his classification as a career
    offender at the sentencing hearing or appeal his sentence.
    Later, however, the defendant filed a § 2255 petition on the
    ground that he had been improperly sentenced as a career
    offender; the defendant explained that he had erroneously
    informed the probation officer that he had been convicted for
    armed burglary, which is categorically a crime of violence
    under the federal Sentencing Guidelines, when in fact he had
    been convicted for attempted third-degree burglary, which is
    not. The district court denied the petition, finding that the
    defendant’s failure to raise his claim at his sentencing hearing
    and by direct appeal constituted a procedural default.
    On appeal, however, we reversed and remanded for resen-
    tencing. Specifically, we found that the defendant was actu-
    ally innocent of being a career offender because he was
    innocent of one of the convictions used to determine that he
    was a career offender. And although we recognized that
    defendant’s challenge to this predicate sentence was proce-
    durally barred, we excused the misstep, noting that "it is an
    unacceptable deviation from our fundamental system of jus-
    tice to automatically prevent the assertion of actual innocence
    simply because a defendant has not observed procedural ave-
    nues available to 
    him." 23 F.3d at 892
    .
    Pettiford contends that Maybeck stands for the proposition
    that the actual innocence exception applies to excuse a proce-
    dural default whenever a movant is "innocent" of any sentenc-
    ing enhancement alleged to be error. And because, he argues,
    the § 924(e) enhancement was erroneously applied to him, he
    habitual offender statutes. 
    See 23 F.3d at 893
    . We see little difference
    between holding that a defendant can be innocent of the acts required to
    enhance a sentence under the Sentencing Guidelines and applying a paral-
    lel rationale in cases concerning the ACCA. See 
    id. (noting that
    "[i]n non-
    capital enhancement cases, the length of a defendant’s sentence may be
    aggravated by factors specified by statute or the Guidelines").
    UNITED STATES v. PETTIFORD                         21
    concludes that he is "actually innocent" of that adjustment.
    We disagree.
    Pettiford misinterprets our holding in Maybeck. We granted
    relief in Maybeck because the defendant clearly showed that
    he had not committed the crime on which the calculation of
    his sentence was based. See 
    id. at 894
    ("There is no dispute
    . . . that [the defendant] was innocent of one of the convic-
    tions used to determine that he was a career offender and he
    was improperly sentenced as such."). It was uncontested that
    the defendant in Maybeck had not committed one of the
    underlying predicate convictions. See 
    id. at 892
    n.7 ("The par-
    ties do not dispute that [defendant] was not convicted of
    armed burglary in 1973."); see also Mikalajunas, 
    186 F.3d 494
    (finding that a petitioner is factually innocent if he shows
    that he "did not commit the crime of which he was con-
    victed"). The defendant’s sentence was therefore erroneously
    enhanced by an armed burglary conviction that he simply did
    not have.
    Pettiford, by contrast, makes no suggestion whatsoever that
    he did not actually commit the 2001 assault. Rather, he makes
    the legal argument that this conviction should not have been
    classified as a "violent felony" under the ACCA.12 This argu-
    ment, even after Maybeck, is not cognizable as a claim of
    actual innocence. See 
    Mikalajunas, 186 F.3d at 495
    (limiting
    Maybeck to its facts and finding that actual innocence does
    not extend to non-factual challenges to the application of sen-
    tencing enhancements); see also Poindexter v. Nash, 
    333 F.3d 372
    , 381-82 (2d Cir. 2003) (rejecting a claim of actual inno-
    cence, premised on the argument that defendant’s three con-
    victions should have been treated as a single conviction
    12
    Likewise, the two 2002 convictions were vacated on legal, rather than
    factual, grounds. They were vacated not because Pettiford did not commit
    the crimes, but instead because the state court "imposed an invalid period
    of incarceration as a condition of probation, and that sentence [was] irrec-
    oncilable with the terms of [Pettiford’s] plea agreement." J.A. 186.
    22                     UNITED STATES v. PETTIFORD
    because he was sentenced for all three convictions on the
    same date, because such an argument is legal, not factual, and
    thus "not cognizable as a claim of actual innocence"). Under
    the reasoning of Maybeck, actual innocence applies in the
    context of habitual offender provisions only where the chal-
    lenge to eligibility stems from uncontested actual innocence
    of the predicate crimes, and not from the classification of the
    predicate crimes. 
    See 23 F.3d at 894
    (noting that in extending
    actual innocence to the habitual offender context, our objec-
    tive is to "protect[ ] defendants from sentencing based on ele-
    ments of crimes for which they are conclusively innocent").
    Thus, we find that Pettiford cannot demonstrate actual
    innocence to excuse his procedural default. Maybeck does not
    excuse his failure to challenge his remaining qualifying predi-
    cates at sentencing or on direct appeal.13
    III.
    In conclusion, we hold that the district court erred in grant-
    ing Pettiford’s § 2255 petition, because Pettiford did not
    show, nor could he show, that the vacated sentences alone
    rendered his federal sentence unlawful on one of the specified
    grounds. We also hold that by failing to challenge his remain-
    ing predicate sentences at sentencing or on direct appeal, Pet-
    tiford procedurally defaulted on his claim that the district
    court improperly enhanced his sentence under the ACCA.
    Finally, we hold that under Maybeck, actual innocence applies
    in the context of habitual offender provisions only where the
    challenge to eligibility stems from actual innocence of the
    predicate crimes. Accordingly, we reverse and remand this
    13
    The government also argues that, irrespective of our understanding of
    Maybeck, Pettiford would not be entitled to relief because his challenge to
    the 2001 assault conviction is predicated on case law that was not avail-
    able to Pettiford at the original sentencing, or that is retroactively applica-
    ble. Because we find that Pettiford cannot demonstrate actual innocence
    to excuse his procedural default, we need not address this argument.
