It has to do with the boot manager so you get to do a repair to the boot area.
Lots written but in short you need the OS CD and then research what commands rewrite all the boot info.
Nutty stuff.

I am migrating to a new computer at the office. The old computer, A Dell Precision T3400 from about 5 years ago & running XP has a second hard drive that I would like to take with me and use in the new computer, which is a Dell Studio XPS something or other, about a year old & running Windows 7.
