    Running a 2012 Mac mini...

    Previously did Bootcamp during Mavericks with a Win 8.1 ISO on thumb drive, all created and run through BootCamp Assistant. No issues.

    Just did a clean install of Yosemite, and formatted the drive before hand.

    Now trying to Redo Bootcamp. The Bootcamp assistant works up until the install process. When it reboots, I get a black screen with "No bootable disc" message.
    Rebooting again and holding option shows me my OS X volume, recovery, and EFI Boot (the thumb drive).

    There is no Bootcamp partition shown, and the install is obviously not complete. Booting to the EFI Boot yields yet another road block, as I cannot get passed formatting in the Installer.....When I get to the partition selection/formatting screen it won't let me proceed, when I expand the error message it tells me that partition can't be used because it has a GPT partition table.

    I am stumped. I am looking to see if anyone has any suggestions, as I've done this a million ways and a million times before, and under Yosemite I can't seem to do Bootcamp.

    I appreciate the instructions, but I don't see why all of the sudden I'm forced to use EFI boot.

    As far as I'm concerned, this is not how Bootcamp is supposed to work. It is broken.
