So I'm getting Windows XP tomorrow, its either home or professional edition, i will be getting windows XP on the 24" imac, not the 20", and will be installing it via bootcamp. i have a 500GB drive in my imac (498GB free), and will be getting windows to run Flight Simulator X Deluxe. How much space should I give to the windows partition in bootcamp assistant while having 3-4GB free space? and if it gets too tight, can i make the windows partition bigger through disk utility without any hassles?
