Well, my MacBook Pro arrives in a few days and I wanting to triple-boot OSX, XP and Ubuntu. It's got a 500GB hard drive so I'm wanting to split the partitions up into 250GB, 200GB, and 50GB. I need to have all 3 on the same computer. I'm following this short tutorial: Has anyone else done this? And is there an easier way? What problems have those of you that did this run into? Thanks Edit: I found the tutorial here. If I were to do all of this successfully, what would happen if I updated to Snow Leopard?
