I want to create a bootcamp partition onto which I can install Windows 7. I have a 500GB HDD which has 50GB of unpartitioned space. I would like to use this unpartitoned space to install windows However when I run bootcamp assistant it only gives med the option to shrink my already existing HFS+ partition. I don't wanna do that. I want to use the unpartitioned space. So what can I do. Does anybody have any idea why bootcamp assistant can't perform this simple step?
