          There are limits to how much you can do with your hard drive when you've booted the recovery partition. Even though the recovery partition is a separate partition, it still locks your drive to some extend, and prevents you from doing "live edits" - primarily modifying the partition table.



          Instead of holding down the ALT key, and booting onto the recovery partition; hold down COMMAND + SHIFT + R -- doing this will download the utilities package from the Internet, and put it in memory. This "unlocks" your hard drive, and let's you re-partition it.
