Might not work,but you might try copying the i386 folder from the XP-CD into the root(C:\) folder. Then go into the registry to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup : Click the setup folder to open. In the right pane,change the 'SourcePath' and 'ServicePackSourcePath' both to C:\ . Reboot and run System File Check and it should now not ask for the disk.
