Boot from Arch ISO on USB with UEFI BIOS [SOLVED]

view story
linux-howto

https://bbs.archlinux.org – 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. dobie2564 https://bbs.archlinux.org/profile.php?id=52001 2012-09-09T13:41:55Z (HowTos)

Stories similar to Boot from Arch ISO on USB with UEFI BIOS [SOLVED]

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

My motherboards firmware must be out of date, because I couldn't get UEFI Shell v2 to work, and that's the one that includes bcfg command.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

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.

UEFI issue? 39 weeks 4 days ago

Well, I understand that it could be specific motherboard issue but Asrock technical support hasn't answered yet. Perhaps somebody has run into the same problems with some other motherboards booting in UEFI mode, I mean power supply power off problem and awakening with usb-keyboard when this option is present in a UEFI BIOS.

I dont have EFI bios what now? 40 weeks 5 days ago

The iso supports both BIOS boot and UEFI boot. Some firmwares have issues booting the isos which support both. Only in such cases should the UEFI boot support be removed.In a similar way it is also possible to create a UEFI-only bootable iso, but neither archiso nor archboot are built that way.

Samsung UEFI dual boot 12 weeks 4 days ago

Thanks, I have booted Linux mint live without bricking but it was via bios. Arch errors out so bad I can't even get to grub on the disc http://imgur.com/VYU7GPf  sorry for the bad quality, quick snap, not focused... So what you guys are saying is that I would have to some how convert win8 to bios then dual boot traditionally.. I read that UEFI allows you to boot multiboot to both.

GRUB2 UEFI BIOS l 8 weeks 4 days ago

I'm using a M5A97 R2.0 (so very very similar AFAICT looking at the Asus website). It will boot UEFI or MBR and you can switch off SecureBoot in the BIOS. You may need to get the latest BIOS from Asus to get the SecureBoot options. I'm using it in UEFI mode without SecureBoot and it's been fine.

Help with UEFI installation 48 weeks 3 days 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.
