Unmountable_Boot_Volume

[Brian]

Win XP Pro.
Had a power outage

Computer will now boot into Safe Mode or Safe Mode with Command Prompt. Any
attempt to boot normally or Safe Mode With Networking results in BSOD:

Unmountable_Boot_Volume

0X000000ED (0X82354900, 0XC000009C, 0X00000000, 0X00000000)

This error apparently indicates either UDMA issues or file system
corruption. I disabled UDMA in BIOS, to no effect, which evidently leaves
just file system corruption.

Is it any help to me that it boots to Safe Mode, or is chckdsk /r from CD
boot my only option?

To fix the Unmountable Boot Volume error:

Boot with XP cd into Recovery Console.
Do chkdsk /p

If there are errors, do chkdsk /r

After Chkdsk is finished in either case, go back into Recovery Console and
do fixboot, and then reboot (hopefully) into Windows.

I had gone ahead with chkdsk /r, and all seemed fine when done. It took a
couple of hours, though.

Thank you.
