For what it's worth, when I try the EFI Boot option: I get "secure boot not enabled, welcome to GRUB!" Then "GNU Grub Version 2.00" with two options (Fedora-18-x86_64-Live-Desktop.is and Verify and Boot Fedora-18-x86_64-Live-Desktop.is) Choosing the first, I briefly see a solid cursor, then "Secure boot not enabled" with a solid cursor, then black screen.
I wonder with it saying ".is" instead of ".iso" is causing any problems?
