    As the title states, I am unable to boot on non-Mac bootable media on my new MacBook Pro 15". Have gone thru Google and MacRumor forums lots of times, but still struggling ... here's the situation.

    ・Mac OS Installation Disc
    -> boots into installer perfectly fine

    ・Windows 7 Installation Disc via Boot Camp assistant or any other non-Mac bootable disc (backup tools, firmware updates, Ubuntu ...) directly

    -> disc shows up when I boot with option key pressed, but when I select the disc, Apple logo shows up with flashing ? folder and a "no-no" sign.

    ・Windows 7 Installation Disc or any other non-Mac bootable disc (backup tools, firmware updates, Ubuntu ...) via rEFIt

    -> error message "The firmware refused to boot from the selected volume. Note that external hard drives are not well-supported by Apple's firmware for legacy OS booting." shows up.

    The discs boot perfectly fine on my Early 2007 Santa Rosa MacBook Pro. Please let me know if there's a good solution to this, or whether this is a Genius Bar matter or not.

    Thanks very much in advance.

    Unfortunately, Command-Ctrl-P-R's not solving the issue ...

    By any chance did you set an EFI firmware password? I seem to recall this being an issue before? If you didn't, I would consider setting one and then removing it.
