DaveH has given an excellent answer

He says: but if you are going to go through all that you might as well reinstall with ME on the primary C: and XP onto D:
i would reckon that too. you must remember these two things when dual booting. 1. Install the older OS first and install the dual-boot supported OS next.
2. Install Win98/ME in the Primary Master (C

and install Win2000/XP in the Primary Slave (D

.
after u install like that, you can format your Primary Slave anytime you want and reinstall Windows 2000/XP as many times as you can, until you DON'T harm the C: drive. Guys, add more ideas. that's all i could say
