Hi, I'm trying to get Windows 7 on my mac and when I go to bootcamp and do a partition I get, 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. My disk is not partitioned and it's formatted correctly so i searched and saw that my HDD is like untidy or whatever it is called and it needs defragged. So i get iDeFrag full version and I do not know how to work it. Then I read I should back up a clone of my HDD and then copy it back to my mac, but i have no external hard drive. How do I go about doing this? Or how do i use iDefrag? Btw, I'm making a partition of 32gb, My HDD has 118GB free and its total capacity is 160GB. Thanks!
