Mark Allen Jackson seeks to appeal the district court’s order characterizing his motion filed under Fed.R.Civ.P. 60(b), as an unauthorized and untimely motion under 28 U.S.C. § 2255 (2000), and dismissing it. An appeal may not be taken from the final order in a § 2255 proceeding unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1) (2000); see also Reid v. Angelone, 369 F.3d 363, 367-69 (4th Cir. 2004). A certificate of appealability will not issue absent “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2000). A prisoner satisfies this standard by demonstrating that reasonable jurists would find that his constitutional claims are debatable and that any dispositive procedural rulings by the district court are also debatable or wrong. See Miller-El v. Cockrell, 537 U.S. 322, 336, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003); Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); Rose v. Lee, 252 F.3d 676, 683 (4th Cir. 2001). We have independently reviewed the record and conclude that Jackson has not made the requisite showing. Moreover, to the extent Jackson’s notice of appeal is construed as a motion to file a successive § 2255 motion, we deny the motion without prejudice because Jackson has not made the requisite *530 showing. See 28 U.S.C. § 2244 (2000), United States v. Winestock, 340 F.3d 200, 208 (4th Cir.), cert. denied, 540 U.S. 995, 124 S.Ct. 496, 157 L.Ed.2d 395 (2003). Accordingly, we deny a certificate of appealability and dismiss the appeal. We grant Jackson’s motion to seal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED
