Vacated and remanded by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Larry Johnson appeals from the district court’s order dismissing as a successive 28 U.S.C. § 2255 (2012) motion his self-styled motion for relief from judgment pursuant to Fed.R.Civ.P. 60(b). We vacate the district court’s order and remand for further proceedings.

“[A] Rule 60(b) motion in a habeas proceeding that attacks ‘the substance of the federal court’s resolution of a claim on the merits’ is not a true Rule 60(b) motion, but rather a successive habeas [application]” and is subject to the preauthorization re *250 quirement of 28 U.S.C. § 2244(b)(3)(A) (2012) for successive applications. United States v. McRae, 793 F.3d 392, 397 (4th Cir. 2015) (quoting Gonzalez v. Crosby, 545 U.S. 524, 531-32, 125 S.Ct. 2641, 162 L.Ed.2d 480 (2005)). By contrast, a “Rule 60(b) motion that challenges ‘some defect in the integrity of the federal habeas proceedings’ ... is a true Rule 60(b) motion, and is not subject to the preauthorization requirement.” Id. (quoting Gonzalez, 545 U.S. at 531-32, 125 S.Ct. 2641). Where, however, a motion “ ‘presents claims subject to the- requirements for successive applications as well as claims cognizable under Rule 60(b),’ ” such a motion is a mixed Rule 60(b)/§ 2255 motion. See id. at 400 (quoting United States v. Winestock, 340 F.3d 200, 207 (4th Cir. 2003)).

In his motion for relief from judgment, Johnson asserted a perceived defect in his § 2255 proceeding, and he raised challenges to his conviction and sentence. Accordingly, the motion was a mixed Rule 60(b)/§ 2255 motion. See McRae, 793 F.3d at 400; Gonzalez, 545 U.S. at 532 n. 4, 125 S.Ct. 2641 (holding that a movant files a true Rule 60(b) motion “when he ... asserts that a previous ruling which precluded a merits determination was in error”); Winestock, 340 F.3d at 207 (stating that “a motion directly attacking the prisoner’s conviction or sentence will usually amount to a successive application”).

The district court did not afford Johnson the opportunity to elect between deleting his successive § 2255 claims from his motion or having his entire motion treated as a successive § 2255 motion. See McRae, 793 F.3d at 400 (“This Court has made ■clear that ‘[wjhen [a] motion presents claims subject to the requirements for successive applications as well as claims cognizable under Rule 60(b), the district court should afford the applicant an opportunity to elect between deleting the improper claims or having the entire motion treated as a successive application.’ ” (quoting Winestock, 340 F.3d at 207)). We therefore vacate the district court’s order and remand for further proceedings.

We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

VACATED AND REMANDED.
