ok so i tried to update my windows xp pro and after it was finished it restarted my computer and now comes up with an error saying

"the following ismmissing or corrupt:System32\Drivers\Ntfs.sys"
Please help me!!!

Try the Recovery Console after booting to the Windows CD. You should be able to reinstall a working NTFS.sys file.
