My Dell Inspiron 1525 computer gets an 'UNMOUNTABLE _BOOT_VOLUME" blue screen error when it was working perfectly fine earlier in the day. Can anyone help me? Thank you

That error often happens, when there is a hard drive problem...

Run hard drive diagnostics: http://www.tacktech....ay.cfm?ttid=287 (or http://www.bleepingc...opic28744.html)
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.

NOTE. If your hard drive is made by Toshiba, unfortunately, you're out of luck, because Toshiba doesn't provide any diagnostic tool.
