I just got a new macbook (black 13.3") and after a couple days decided to install windows with bootcamp. Now that I have a copy of Office 2008 mac edition I would like to turn that XP (fat32) partition into a Ubuntu partition. Is there a way to do this without affecting my OS X partition? In short I want to turn a OS X & XP dualboot into a OS X & Ubuntu dualboot without losing anything on the OS X partition.
