I recently bought an Asus laptop with Windows 8 preinstalled and had hoped to dual-boot it with Ubuntu 12.10. I created a USB but my USB only boots when I have Boot Security disabled. In that mode, I am unable to resize the Win8 partition to create room for Ubuntu. When I enable Secure mode, it allows me to choose the try live option but does not actually boot once I choose it. Any suggestions? I have used https://help.ubuntu.com/community/UEFI as my guide but, since it will not boot with security enabled, I am stuck.
