"Unmountable Boot Volume" points to a problem with the hard drive. Either there are corrupted boot files or that a sector of your hard drive has already been damaged and the computer can no longer read the information off it.
This problem may or may not be fixed(if the hard drive has already gone bad).
Here's a possible solution:
1. Insert your Windows XP disk in your CD/DVD drive.
2. Boot to the CD/DVD drive. If done successfully, you'll receive a "Press any key to boot to CD" message. Press any key. It should now load the installation files for Windows.
2. The next screen should provide you options to repair Windows using Recovery Console or Install Windows. Press "R" to go to Recovery Console.
3. It may ask you for an Admin password, type your password then hit Enter. If not, just proceed to the instruction below.
4. Type chkdsk /p on the Command Prompt then hit Enter. It will now proceed to scan your computer for possible bad areas and will attempt to fix them. Wait for it to finish.
5.Type fixboot then press Enter. This will attempt to fix the Boot Volume. If it prompts you, type "Y" (Yes) then press Enter to continue. Wait for it to finish.
6. Type exit then press Enter to let the computer exit the Recovery Console and restart. Let the computer start normally.
