bsod - Why can't I repair my Windows XP installation? Partitioned [unknown]

I have a computer that I need to do a installation repair on. It's running a SATA drive and have tried everything:

• fixboot


• fixmbr


• slipstream XP using nlite to include the SATA drivers


• chkdsk /r to try to fix any disk errors (just freezes @ 50%)

The problem with the computer is winxp won't boot, not even in safemode. It just restarts. I froze the error and got:

UNMOUNTABLE_BOOT_VOLUME
stop: 0x000000ED (0x8a635590,0xc0000009c,0x00000000,0x00000000)

When I go to try to do the repair using the Windows XP CD, I click enter to view partitions, then I am supposed to see an option to choose 'R' for repair which will reinstall the Windows installation but keep documents and settings and applications. But no option is available and the partition just says

Partitioned [unknown]

Can anyone give me some advice or tips? I'm running out of ideas.

Answer

Sounds like you have partition damage, I would suggest using Testdisk to attempt repair of the partition(s). Do plenty of reading before you use the software.
