Can't Load UEFI Shell From USB

view story

https://bbs.archlinux.org – I'm trying to install Arch on an Asus Zenbook Prime UX31A. It already has Windows 7 x64 on it and a UEFI system partition doing the bootloading.I followed the steps for creating a UEFI bootable USB from the ISO. When I get to the UEFI device selection, the thumbdrive correctly shows up as "UEFI: Generic USB" (or something) but selecting it just fails silently and it goes on to load the next thing in the boot order. What could be going wrong here? silverhammermba https://bbs.archlinux.org/profile.php?id=47829 2012-09-23T01:40:49Z (HowTos)
