PER CURIAM:
Mark Bumphus El, a North Carolina inmate, seeks to appeal the district court’s order accepting the recommendation of the magistrate judge and denying relief on his 28 U.S.C. § 2254 (2012) petition. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1)(A) (2012). 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) (2012). When the district court denies relief on the merits, a prisoner satisfies this standard by demonstrating that reasonable jurists would find that the district court’s assessment of the constitutional claims is debatable or wrong. Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); see Miller-El v. Cockrell, 537 U.S. 322, 336-38, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003). When the district court denies relief on procedural grounds, the prisoner must demonstrate both that the dispositive procedural ruling is debatable, and that the petition states a debatable claim of the denial of a constitutional right. Slack, 529 U.S. at 484-85, 120 S.Ct. 1595.
We have independently reviewed the record and conclude that Bumphus El has not made the requisite showing. Accordingly, we deny a certificate of appealability, deny leave to proceed in forma pauper-is, and dismiss the appeal. 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.
DISMISSED
On appeal, we confíne our review to the issues raised in the Appellant’s brief. See 4th Cir. R. 34(b). Bumphus El does not challenge the basis for the district court’s disposition of his various claims in his informal brief. Thus, Bumphus El has forfeited appellate review of the court’s order. See Williams v. Giant Food Inc., 370 F.3d 423, 430 n.4 (4th Cir. 2004).
