https://bbs.archlinux.org – 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.

Learned a good bit in the process though. Now i know how my system works from boot to the loading of the GUI and its helped with trouble-shooting.

Seems the problem is here:mount /dev/sda1 /mntmkdir    /mnt/homemount  /dev/sda3 /mnt/homemkdir   /mnt/bootmount  /dev/sda1 /mnt/bootI think the UEFI partition must be at least 512MB + or -Separating the partition and mounting of the EUFI system worked.

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.

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.

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?

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.

Can't Load UEFI Shell From USB 35 weeks 4 hours ago

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.

My motherboards firmware must be out of date, because I couldn't get UEFI Shell v2 to work, and that's the one that includes bcfg command.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.

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.
