[SOLVED] Can't Load UEFI Shell From USB

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?

Does it boot with other UEFI distros??

Maybe you can also try archboot.

Re: [SOLVED] Can't Load UEFI Shell From USB

I could give Ubuntu a go.

I have some more general UEFI questions regarding Arch too. Is it possible to boot Arch with UEFI without using a UEFI shell? Say by doing a regular install and then mounting the UEFI partition and manually configuring it to boot Arch? Really the main issue is that I can't currently use efibootmgr because I can't boot the USB in EFI mode.

Re: [SOLVED] Can't Load UEFI Shell From USB

I had problems with the 2012.09.07 installation ISO so I used the 2012.08.04_04-00-01 netinstall from the snapshots.

Follow creating a UEFI bootable USB from the ISO exactly to create the USB.

What were your problems? I tried to install it with UEFI yesterday, but couldn't get any longer then UEFI shell. The install wouldn't start.

Re: [SOLVED] Can't Load UEFI Shell From USB

Did create the 2012-09 UEFI USB succesfully and it did boot.
wanted too reinstall arch because of SSD.

So maybe you want checkout the layout of your USB and size of the files!

Re: [SOLVED] Can't Load UEFI Shell From USB

I ended up using the archboot ISO, which worked. Odd that the regular ISO didn't...
