Unmountable Boot Volume Error

[Guest]

I know a million similar questions have been asked, but I don't know if
anyone knows about this or not. I got the stupid error message, along with
the hexadecimal numbers 0x000000ED(0x82F99900, 0xC000006, 0x00000000,
0x00000000). I haven't installed any programs or hardware lately, so I
assume it's some disk error and I need to run the chkdsk (or whatever it is)
from the CD. I have a problem though. I'm a college student at home on
break, with my Windows CD at school. I'm running XP Pro on my laptop, and my
parents' computer is running XP Home. Can I use that CD and run the chkdsk
thing off it and fix my problem or do I need to hunt down an XP Pro CD or do
I need to do something else entirely? Any help is much appreciated.

You can run CHKDSK from the xp cd in recovery,but one doesnt need the
xp cd,simply go to run,type:cmd In cmd type:CHKDSK C: /F Agree to restart,
then type:EXIT Restart computer,utility will run on restart.

But I can't get Windows to even start... no safe mode, no command prompt, no
anything. Anything I've tried I've gotten a blue screen with the
"UNMOUNTABLE_BOOT_VOLUME" along with hex numbers I listed earlier. From what
I've understand from looking at the support stuff the only options I have
left are running the CHKDSK or reinstalling Windows, both which require a CD
that I don't have. Any other ideas?

Youcan not useyour parents CD, they need to be identical.

Power off
Desktop:...Open the case and reseat the hard drive IDE ribbon cable at both
ends.
Laptop:... simply remove and reinsert the hard drive.
If that fails:

Otherwise go to the website of the hard drive manufacturer and download
their hard drive diagnostics.

Do you have a hard drive overlay such as Max Blast?
Windows XP sometimes has issues with overlay software.
You may need to perform a Clean Installation without their overlay software
which is not needed anyway.
