Unmountable boot volume in XP
The unmountable boot volume is one of those errors that do happen to many people. We will go over possible causes and a solution.
The reason most people end up getting the unmountable boot volume error is because of an improper shutdown. What normally happens is something was being written to your boot.ini file and during that time it got corrupt. There are many reasons for this but luckily there is an easy solution.
The first one is to take the windows cd that came with your computer. Boot to the windows CD and when asked hit R for the repair function. You will see a dos prompt asking what windows version you want to load and also may be asked for an admin password. In most cases just select 1 and then hit enter because many people never setup the main admin account to have a password. If you do have one enter it in.
Now type “chkdsk /p” with out the quotes. Let that run and then type “fixboot” again without the quotes. When asked hit the Y button for yes. Reboot and most likely your issue is now resolved. If this did not work do the above again but this time run chkdsk /r
So what happens when you do not have an XP disk?
If you do not have an XP disk then you can always download a bootable disk from places like http://www.bootdisk.com . Once downloaded on a computer you will need to copy the boot disc files over to a CD or floppy. If the disk has the ntfschk utility on it that will work great to fix this issue. Boot to the disc and type “ntfschk C: /f” with out the quotes. Doing this will scan your drive and also repair it at the same time.
