Whenever I turned my computer on this morning a blue screen came up sayin UNMOUNTABLE BOOT VOLUME. I tried restarting it in safe mode like it said to, but the blue screen kept coming up. It had this error message at the bottom of the screen Stop: 0x000000ED (0x80A91D98, 0xc0000032, 0x00000000, 0x00000000). Can anyone help me figure out what's going on. Everytime it does this I have to reinstall Windows XP and everything on my computer is erased. Please help!
