I restarted my computer today and right after it started booting from my C: drive, an error came up that said something like "Windows cannot find the file C:\windows\system32\ntfs.sys because it is missing or corrupted." It suggests that I use the recovery disk to fix it, but I don't have the recovery disk, so I'm kind of in trouble. Luckily, I had some Linux LiveCDs laying around, so I used one to boot up my system.I think that this might have something to do with me trying to change my boot screen, but I didn't mess with that particular file, so I'm not sure. Also, I haven't done anything to the RAM lately. I have Windows XP Professional SP2, and I was wondering if anybody had any suggestions as to what I should do.
