UEFI booting with GRUB2

Alright I have been going at this the entire weekend and still can't figure it out, so I appreciate any help I can get.

I followed the GRUB2 wiki, UEFI section and did everything from a chroot. The only step I skipped was this

sudo modprobe dm-mod

It gave some error and I didn't think it was necessary. Let me know if I'm wrong. I followed the wiki all the way to the running of efibootmgr in a livecd and the furthest I managed to get to when I rebooted was a Grub2 shell. I tried booting manually by typing these

set root=(hd3,gpt1)
linux /vmlinuz26 root=/dev/sdd3 ro
initrd /kernel26.img
boot

here's my harddisk configurations if it matters

/ - sdd3
/boot - sdd1
/boot/efi - sdd4
/var - lvm on a raid5 array /dev/mapper/array-var
/usr - lvm on a raid5 array /dev/mapper/array-usr
/home - lvm on a raid5 array /dev/mapper/array-home

trying to boot manually in the grub shell got me nowhere. The screen went blank for a few seconds and my system rebooted. I ended up in the grub shell once again. Any ideas???

Re: UEFI booting with GRUB2

What is the mobo you are using? May be https://help.ubuntu.com/community/UEFIB … ut%20noefi might help.

Re: UEFI booting with GRUB2

I'm using the ASUS p8p67 pro. What should I try first? Is recompiling the kernel the only way? I'm not too familiar with compiling the kernel, I usually only apply kernel updates via Pacman. Anyways I've got to get going now and won't be able to try out the solutions till a week later. Let me know which solutions I should try first though, I'll get to it once I'm back. Thanks.

Re: UEFI booting with GRUB2

I just read through the links. Guess I should try the kernel. A quick question, I can simply use an aur helper like yaourt and do yaourt -S .... And it should compile the kernel right? The latest 3.0rc3 kernel already has all the patches so I shouldn't need to do anything else other than getting it from the aur?

Re: UEFI booting with GRUB2

Okay i installed the kernel and it can boot up now, but I still have 2 issues.

1. I can't get to the grub2 menu. I am only able to get to the grub shell and have to boot manually everytime.

2. Upon boot, i get to kdm and I can't login because my keyboard/mouse don't work. Even numlock doesn't work. My keyboard works in single user mode though.

Re: UEFI booting with GRUB2

Has anybody worked out a straightforward way to install Arch to a GPT partition of an SSD, using Grub2 and booting via efi?

@dhave
No, but when kernel 3.0 hits mainstream you will be able to do a netinstall, and install grub2, and everything should work. Anyway i think going without GPT is the best choice at least for the time being.

@Vighi: So, have you installed kernel 3.0 yet? I've read several good reports like this one, but I'm still waiting for someone to report straightforward installation of Arch to a GPT partition of an SSD, using Grub2 and booting via efi.
