Help! Unmountable Boot Volume Error on XP Professional

[tribdog]

My girlfriend's sister called me up for computer help, but I don't know much about computers. So here's the problem:
She's using XP Professional. Everytime she turns it on she gets a blue screen, Unmountable Boot Volume. Does that mean there is a problem with the hard drive or the information on the hard drive?
I guess she gets about halfway through the Windows loading process before the screen pops up.

When I saw the title I knew right away it's a Windows problem. You know the guy who invented Ctrl+Alt+Del was quoted as saying He invented it, but Bill Gates popularized it. Bill didn't laugh..

F10 repeatedly on startup to do a system restore. If needed to.
