Alright so the name of the thread is the name of the error message I get when trying to partition my HD. Here is the whole thing The disk cannot be partitioned because some files cannot be moved. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again. Simple enough.... minus the fact i have nothing to back up my HD on and not really willing to pay 100 dollars (college student). Is there any way around wiping the HD to partition it? I have read that the problem is there is not continuous space for it to partition, meaning i need to defrag or compact my HD so it frees up consecutive space. Does anyone have an ANSWER? I have read other threads on here and they are not helpful!
