So I boot the computer this morning and I get a message: "ntfs.sys is missing or corrupt." So I go to Microsoft's site, and they list instructions on how to fix the problems. This involved renaming the old ntfs.sys file and replacing it with one off of the Windows XP CD. Fine I did that without a hitch, and while I don't get the error message anymore, all my PC does is go to the Windows XP Pro loading screen, and reboots. It's a continous loop. Any ideas?
