    Can you post the output of the following Terminal commands?

     

    sudo gpt -vv -r show /dev/disk0

    sudo fdisk /dev/disk0

     

    Sudo commands require your password, which is not echoed back to you. You may also see a warning about improper use, and potential data loss, if abused.

    After you partitioning, if you get a blinking cursor, boot back into OSX and post the output. Are you using EFI boot by using the Alt/Option key?

    Do not use Alt/Option key to interrupt the installation. Please ensure you are using a USB2 flash drive for BC Drivers and ISO.

    This may be an easier problem to fix. Please ignore the i386 MBR error message, but all other error messages should not be ignored.

     

    In OSX Terminal, 

     

    sudo fdisk -e /dev/disk0

    p

    setpid 4

    07

    flag 4

    p

    w

    y

     

    Reboot and test.

    Your 2012 MBP does not support EFI boot fully. Can you verify that the USB you are using is a USB2 device? Here is an example.

    Windows installer has no USB3 drivers. BCA will happily create a USB3 device, but the Windows installer will fail, because it cannot find drivers or the installer. This is why you see a "_" cursor.

     

    Please find a USB2 device, verify it, and recreate the installer via BCA and test.
