[UNPUBLISHED]

Missouri inmate George E. Nixon appeals the district court’s 1 orders dismissing his 42 U.S.C. § 1983 action. Having carefully reviewed the record, we conclude that the district court was required to dismiss Mr. Nixon’s lawsuit for failure to exhaust administrative remedies. See 42 U.S.C. § 1997e(a) (prisoner shall not bring § 1983 prison-conditions lawsuit before exhausting available administrative remedies); Johnson v. Jones, 340 F.3d 624, 627 (8th Cir. 2003) (dismissal required when inmate has not administratively exhausted before filing lawsuit); Graves v. Norris, 218 F.3d 884, 885-86 (8th Cir. 2000) (per curiam) (dismissal proper where at least some of claims were unexhausted).

Accordingly, we need not address Mr. Nixon’s remaining arguments on appeal, and we affirm, but we modify the dismissal to be without prejudice as to all of Mr. Nixon’s claims. See Chelette v. Harris, 229 F.3d 684, 688 (8th Cir. 2000), cert. denied, 531 U.S. 1156, 121 S.Ct. 1106, 148 L.Ed.2d 977 (2001). We also deny Mr. Nixon’s pending motions.
