Hey there everybody... haven't been here in a while but I am in need of some help for my girlfriend. Her computer is giving her problems, let me go through the steps.

Step 1, she starts up the PC, it asks the "Start the Computer Normally, Start in Safe Mode..." blah blah, you know what screen I am talking about. Whichever option she chooses, it'll take her to the screen as if it'll load up.

Step 2: She gets a blue screen with white text that says something about "UNMOUNTABLE_BOOT_VOLUME" --- I am not sure, I've run out of idea's... hell, even my computer tech teacher is stumped.

Step 3: I need ya'll professionals to help me out with what the problem could be. If anybody could help, I'd kindly PayPal you $20 for your help, its for my girlfriend and it sucks to see her bored because her PC doesnt work... anybody willing to help? Thanks.
