My sister and her kids use the same computer. We bought xp Pro for her and installed it on a seperate Hard drive because she works from home. Her kids play and download on the original HDD. If we wipe the Original HDD (kids stuff) and go through the recover process, will we still be able to boot into her HDD? Will the MBR get messed up? What is the best thing to do? It would take so long to get the kids strightened out, that it is easier to reinstall.
