The issue is pretty simple, but I can't install Win 7 64 bit. I've got the win 7 install disk installed on the usb stick (4gb lexar that was sitting around). Bootcamp partitions the drive, reboots, get into the windows 7 install menu, format the bootcamp parition and then when clicking next I get this error: Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information. And that's it. Can't continue on. I've swapped ports, doesn't make a difference. I have no external drives, nothing else is plugged in. What are my options?
