|A partition image does not copy the MBR.|
I think I know what you're thinking, Wanderer. If you image a partition and later restore it to that same drive, that will work. That's because the MBR is still there and matched to the partition.
FWIW to XP users: When you click on the 'Command Prompt' you are just causing the 'Command prompt' to be displayed. This prompt gives you access to NTVDM.EXE, the 'NT Virtual DOS Manager'.
