blue screen of death #2

My girlfriend's computer has been acting strange lately, and now when she turns it on, windows won't load and I get a blue screen with a nasty little message. I can't even get it to run in safe mode. Here is the message:

A problem has been detected and windows has been shut down to prevent damage to your computer.
unmountable_boob_volume

tech info
stop:0x000000ED



any idea how i can fix this to at least copy item from her harddrive before reformatting or something?

thanks

it appears that this is my problem:

"Damaged File System
If the second parameter (0xbbbbbbbb) of the Stop error is 0xC0000032, then the file system is damaged.

If this is the case, restart the computer to the Recovery Console, and then use the chkdsk /r command to repair the volume. After you repair the volume, check your hardware to isolate the cause of the file system damage. "

my question is, if i do this, it doesn't change or reformat the harddrive in any way correct? no saved information should be lost, it will just fix my windows right?

thanks for the help. sorry about the delay in replying.
