How Do I repair the registry in Windows XP? The system will not work in safe mode or "last config" mode. When attempting to reformat the C drive by starting up off the Windows XP CD It also crashes-blue screen. The Error code is 0x00000051. Several srticles dealing with Registry errors suggest installing a hotfix however not being able to boot up the system at all makes that impossible. I don't understand why the registry error should be a problem when booting up from the CD since all files needed for operation ought to be on the CD, no? Any suggestions would help.

thanx.

Registry API Blue Screen
If you?re writing code that manipulates the registry, you might encounter a bug in one of the registry API calls that causes a system to crash with a stop code of 0x00000051 ( REGISTRY_ERROR). The information about this bug is scanty and doesn't identify the function that generates the error. However, the Microsoft reference article "You Receive a 'Stop 0x51 (REGISTRY_ERROR)' Error Message" states that the blue screen occurs because of a coding error that produces a race condition on the function?s input buffer. The good news is that you can call Microsoft Product Support Services (PSS) for the fix, new versions of five core OS files?basesrv.dll, kernel32.dll, ntkrnlmp.exe, ntkrnlpa.exe, ntkrpamp.exe, and ntoskrnl.exe?-with file release dates of May 6. The bad news is that this is a Post-Service Pack 3 (SP3) fix.

Since it sounds like you are trying to reinstall win xp, if you have a floppy drive then go to www.boot.com and download the installation floppies. It takes 4 of them. You can also get them off of your Win XP CD. Try a fresh install booting off of the floppies instead of the CD. Hope this helps.
