Lori D. Blakely seeks to appeal the district court’s order denying some of the claims raised in her 28 U.S.C. § 2255 (2000) motion. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2000), and certain interlocutory and collateral orders. 28 U.S.C. § 1292 (2000); Fed.R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. *906541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order Blakely seeks to appeal is neither a final order nor an appealable interlocutory or collateral order. Accordingly, we dismiss the appeal for lack of jurisdiction and deny a certificate of appealability. 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
