SO I just got my mac today, I tried to install windows 7 via bootcamp and it installs but then when it reboots the screen turns off and nothing happens...I wait and wait and the screen stays black until I reboot the computer and hold option to boot osx. Its windows 7 prop 64bit and it wont boot into windows at all, the display will show something if I try to boot in safe mode but it only gets as far as setting up for first use and then pops up an error saying you cant do that in safe mode
