GPT bootloader issue

Hello!

I'm having some trouble to understand that one. Installed Arch, skipped the bootloader because grub legacy doesnt supports GPT and I dont know how to setup syslinux/extinux. Here's the scenario:

500GB HDD GPT partitioned:

1 - EFI partition (Created by OSX Lion installation - Hackintosh)
2 - Lion HFS+ partition
3 - Windows partition (NTFS)
4 - Arch linux (ext4)
5 - 2MB free space (I heard I need one to install grub2)

How can I boot arch linux? I plugged the systemrescuecd live usb, booted into its live mode and performed:

$mount /dev/sda4 /mnt/sda4   (sda4 = the arch partition)
$grub2-install /mnt/sda4

it gave me an error saying that /boot/grub2 wasnt readable at boot and that the install was impossible.

In order to triple boot, I need to install grub (or any bootloader that solves my problem) under the arch partition instead of the MBR so lion bootloader can deal with all the OS'es.

Thanks

Re: GPT bootloader issue

I'm not a noob or anything.. I just must be missing some detail, cause I never dealt with GPT partitions before and the Mac is a must have for me so I'll stick with GPT. I've heard that Fedora 17 can handle this automatically but I wanted to use arch.. God, i hate to get in trouble by simple stuff haha

Have you seen this?

More precisely, "3. Bootloader Support".

Re: GPT bootloader issue

Yeah! I know I have to use Grub2 or syslinux but I'm unable to install grub2 and doesn't really know how to use the syslinux on the partition. Again, I can't install the bootloader to the MBR, must be under the linux OS partition.

Thanks

See also pages on GPT and GRUB2, including notes on Macs. No idea if these apply in your case.
