A friend has an XP-home system that became infected/unstable/unusably slow. This was on a Dell 3100 with, of course, only a reinstall partition. Before I had time to get there some other 'helpful' person had used the F12 reinstall, but somehow created a new install altogether on Drive D: (that is alway factory-built by Dell these days and used for Ghost images.) Now there are two boot options, and the one on D: is the only working one. Since I am going to be blamed if the machine fails again, I want to re-establish the C: drive copy correctly, and take a proper image onto drive D: for backup (not the other way round). I know the copy currently on drive D: will have a registry full of D: instead of C:, so a straight partition copy of D: to C: will not work without further attention. It occurred to be to use Drive Mapper from my copy of PowerQuest partition magic. Has anyone done this successfully, or is there a better way still to do this job ?
