Can't Load UEFI Shell From USB

view story
linux-howto

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)

When your setting up Arch with a UEFI BIos motherboard its easier if you boot through the UEFI shell on a usb disk then through the install cd. It cleans up a lot of headaches. Read the post below to find out how.https://bbs.archlinux.org/viewtopic.php?id=148155

GRUB Not Loading Arch Install 42 weeks 6 days ago

Logical partitions means it's MBR-formatted and not GPT-formatted.For UEFI boot, GPT is recommended.https://wiki.archlinux.org/index.php/UE … n_in_LinuxNote: It is recommended to use always GPT for UEFI boot as some UEFI firmwares do not allow UEFI-MBR boot.

Help with UEFI installation 1 year 14 hours ago

Which instructions? I don't see how you can have "followed exactly the steps" as described on overclockers *and* all the ways described in the wiki.If you installed grub2 as described in the wiki while in BIOS mode, all you need to do is boot in UEFI mode to complete the installation. I used Ubuntu to do this but anything which will boot UEFI will do.

But if I do select the UEFI boot option, then when the system tries to boot, I get the following message:"No loader found.

It varies on different manufacturer motherboards.  I've got two recent ASRock mobos (different form factors) and the UEFI implementations on them are a bit different.   The better one, recognizes UEFI on a USB stick and gives the option to boot it as BIOS or UEFI.

My motherboards firmware must be out of date, because I couldn't get UEFI Shell v2 to work, and that's the one that includes bcfg command. Also, I couldn't boot anything other than my pendrive in UEFI mode.

https://gitorious.org/tianocore_uefi_du … I_boot_USBIs the guide above is all i need when setting Windows 7 + ArchLinux in a PC with UEFI? From what i understand you do all the config in the USB driver and then you install without hassle?

Thanks for the response. I originally thought you could only install a boot loader on a UEFI motherboard if your boot drive was using GPT, but from what I understand of your post this is not required and I can either install Arch Linux in UEFI mode with an ESP or in legacy mode without an ESP.

Sorry, I'm having trouble getting the hang of this whole UEFI thing:). Would I have already have the UEFI shell on the usb that I'm installing Arch from? I've followed all of the steps to set up EFISTUB in the Beginners' Guide, and if I could just copy the shell to another directory, that would make it easier.
