fjnorb Posted March 13, 2014 Share Posted March 13, 2014 Acquired Mountain Lion Niresh dmg. Followed the instructions to write it to an 8GB USB drive with Disk Utility. Ran Pen Bootloader.pkg and installed it to the USB drive. Booted off the drive on my AMD machine. After normal BIOS boot screens, it clears the screen, displays a single numeral 7, with a flashing cursor after it, and does nothing. What have I done wrong?
