Bootcamp: How do you install win7 when XP is already installed, but keep the XP partition untouched. I Have 2 partitions, a 320gb windows xp setup and a OSX snow leopard 320gb partition. I want to take 60gb from preferably the OSX partition (or maybe even the xp one) and create a windows 7 partition (total HDD 640gb). does anyone know how do to this or if it is even possible
