A "cloned" drive is a perfect copy - everything in the same place including MBR. The best way to do it is to do it OUTSIDE of the Windows OS - boot with your cloneware's bootable CDR or floppy option. I do this every week - but would never use Norton Ghost - it is too expensive, complicated and not very user friendly. Today's best software for cloning is Acronis TrueImage7. It auto-burns you a CDR that is bootable and does everything. Never an error or problem. I do clone three drives a week on three machines.
