What I have: Original Windows 7 Pro disk from Microsoft on hand Downloaded exact ISO copy from Microsoft as well if need be External Samsung optical DVD drive USB drive(s) What I don't have: Internal original optical drive; the bay is empty. Patience to use VM's and WinClone and all that BS. Sorry for the harsh tone, but I am losing my mind editing .plists and rebooting a hundred times in a day; erasing USB drives when this all used to work years ago. I was pretty sure it was possible to install Windows 7 on my Late 2011 MacBook Pro from an external optical drive. I'm not even asking to use a USB. Why is it that I have all the official files from Microsoft and a USB/DVD drive but am forced to use an internal one which is broken for like 90% of Mac owners. I'm seeing a black screen with a cursor on boot or a black screen saying no bootable device... after using Boot Camp Assistant. I tried not using the assistant and making a Fat32 partition on my on and bootable usb, but that method failed as well for some illogical reason. Please help me or at least explain some restrictions that I can never get around regarding my machine and Boot Camp. Thanks!
