Error while partitioning in boot camp
So I am trying to install windows to my MacBook Pro. I have a windows 7 disk and I go through the steps in boot camp, but once I get to choosing the partition and to actually installing, it goes a quarter way through and days it couldn't partition because an error occurred. Nothing else. Just that. Some assistance would be greatly appreciated gents.
MacBook Pro, OS X Mountain Lion (10.8.3)
