Bug description:
  Summery:
    I downloaded images from ubuntu.com and use usb-creator-gtk to create bootable usb.
    Then use the usb key to boot on my ASUS X201E laptop and it is always failed to boot to OS.

    These images are all failed:
      ubuntu-12.04.2-desktop-amd64.iso
      ubuntu-12.10-desktop-amd64.iso
      ubuntu-13.04-desktop-amd64.iso

    I also enabled grub2 debug message, and found they all fail on:
      loader/i386/efi/linux.c:69: Asking shim to verify kernel signature.

    The BIOS revision of ASUS X201E is 209 which can be downloaded from
  official ASUS website.

    Additionally, Win8 and Fedora-18 can be booted and installed on this
  platform.
