ok so I have spent the better part of the day pouring over videos and macrumors learning the in's and out's of installing win7 via bootcamp. seems pretty simple. UNTIL i tried it myself - i opened bootcamp assistant and tried to partition the drive, instead I got this message: The Drive cannot be partitioned because some files can't be moved It says I need to back up my stuff and reformat the drive WTF??? I got a 250GB HD with 120 GB free. I was only trying to create a 25GB windows partition. Any ideas what may be causing that error message?
