I have a computer that will not boot. XP Home. Has message system32\drivers\ntfs.sys missing or corrupt. I have tried to copy file from XP cd in recovery console using copy d:\i386\ntfs.sys c:\windows\system32\drivers I get a message access denied. If I used dos and try to access i386 from from cd I get access denied. It is a hidden system file. I am not the best with dos commands.
