I re-installed Leopard when I got my iMac in order to rid it of a factory-installed OS (for some reason I live safer knowing it was I who installed it). However before that, I had messed with Boot Camp and installed Vista on the partition (32GB). When I re-installed Leopard I (stupidly) accidentally formatted the partition created by Boot Camp. Now when I go into Boot Camp Assistant, it tells me that it cannot remove the partition and put it back to one hard drive (Macintosh HD). What can I do? Hopefully there is a way to reverse this?
