So I have 22gb left on my MBP (I only have a 100gb HD), and I have vista ultimate, and I want to install it so i can play games (well, I'm only interested in one game right now, B&W 2, but anyways). I don't think I'll have enough room on my HD if I partition a 15g space - I'd feel too cramped. Oo, actually, I just thought of this - since I can access my windows partition while running osx, could I put all of my itunes/iphoto on the windows partition, and still have them accessible for itunes/iphoto? They're what takes up the most space. Anyways, if I can't do that, can I boot windows from an external hd and have it be fast enough to play games?
