             Appeal from the United States District Court
                  for the Northern District of Texas
                         USDC No. 3:05-CV-964
                         --------------------

Before KING, WIENER, and OWEN, Circuit Judges.

PER CURIAM:*

     Hubbard Bell, Jr., federal prisoner # 18370-077, appeals the

district court’s dismissal of his purported 28 U.S.C. § 2241

petition, which the district court construed as arising under

28 U.S.C. § 2255 and dismissed without prejudice for lack of

subject-matter jurisdiction.

     A petition filed under § 2241 that raises errors that

occurred at or prior to sentencing generally should be construed

as a § 2255 motion.    Padilla v. United States, 

, 426

(5th Cir. 2005).    However, “a § 2241 petition that attacks

     *
       Pursuant to 5TH CIR. R. 47.5, the court has determined that
this opinion should not be published and is not precedent except
under the limited circumstances set forth in 5TH CIR. R. 47.5.4.

custody resulting from a federally imposed sentence may be

entertained under the savings clause of § 2255 if the petitioner

establishes that the remedies provided under § 2255 are

inadequate or ineffective to test the legality of his detention.”

under the saving clause of § 2255, Bell must

show that the remedies provided under § 2255 are “inadequate or

ineffective to test the legality of his detention.”    See 

make a claim “(i) that is based on a retroactively

applicable Supreme Court decision which establishes that the

petitioner may have been convicted of a nonexistent offense and

(ii) that was foreclosed by circuit law at the time when the

claim should have been raised in the petitioner’s trial, appeal,

or first § 2255 motion.”    See Reyes-Requena v. United States, 

, 904 (5th Cir. 2001).

       United States v. Booker, 

(2005), has not been

made retroactively applicable to cases on collateral review.     In

re Elwood, 

, 213 (5th Cir. 2005); see also 

.    Bell’s Booker claim thus does not satisfy the

mandates of the savings clause of § 2255.    

.    Bell’s argument that he is entitled to “mandamus

jurisdiction” fails because he has not shown that either the

district court or this court had a duty to grant the relief he

requests.    See In re Stone, 

, 1034 (5th Cir. 1997).

       AFFIRMED.
