I think there's some sort of error with my MacBook's disk drive that's causing it to not install other operating systems on it from the disk, but once in a blue moon it can boot up a live cd of linux. I kind of need to install Windows 7 on this MacBook, so I was wondering, what if I were to take the Windows 7 install DVD, convert it to an ISO file, and make a third partition restored by the iso, then boot up from that third partition of the Windows 7 installer, and copy that onto the blank partition, then once windows 7 is installed, remove the installer partition so it's just OS X and Bootcamp...? Sound good? I did it to dual boot Lion and Mountain Lion on my other MacBook.
