Hey Jus Copy the I386 folder to ur C Drive and Now you will need to tell your computer you now have the files on your PC. We do this is the registry (type regedit in the Run box on the start menu) by navigating to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
You will see various entries here on the right hand side. The one we want is called: SourcePath
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: C:\
Simply double click the SourcePatch setting and a new box will pop up allowing you to make the change.
Now restart your computer and try scannow sfc again!...
Hope This Helps
