UNMOUNTABLE_BOOT_VOLUME
pLSS HELP
This error can happen if you or someone else has been messing with the file: boot.ini.
To fix this:
1. Boot the computer to the WinXP CD.
2. When you see the "Welcome to Setup" press R.
<You should now see a dos prompt>
3. Now type: "chkdsk /p" (without the quotes) and hit Enter.
4. When this process is complete, type: "fixboot" and hit Enter.
5. Press "Y" and Enter at the prompt.
6. Now type "exit" and hit enter. (without quotes).
I hope this info helps.
