When I use the above tool on my computer (home built) I have no problem, but when I try to use it on a purchased computer for which no disk has been supplied it will not work. The computer keeps asking for the original disk. I know there is a recovery XP program on a partition is there any way to point this tool to this partition. If not then why did Microsoft continue to include this very useful tool knowing that no one supplies a disk today when the operating system is pre installed. Is there any other program that can be used to perform the same repair function which does not require the original disk.
Many thanks in antisipation

It probably has an entry pointing to your CD-ROM drive, and that is why it is asking for the XP CD. All we need to do is change it to:

Now restart your computer and type into run cmd, then in command box type sfc /scannow (note space).
