My friend installed ArchLinux on a MacBook Pro alongside Mac OSX and Windows to try it. He's power user, so I only needed to help with the bootloader. Arch Linux's described installation of GRUB did not work (grub did not detect the 4th GUID partition it was installed on).

I heard that with EFI GRUB 2 works, and it did. The problem is that it required embedding in an ext4 partition that had too little space for it. Is it possible to install GRUB 2 on an ext4 partition without embedding?

Your best bet on Mac hardware is to use rEFIt. I've used that and it works well.

It is installed but as far as I understend it does not boot Linux directly but it have to chainload one. – Maciej Piechotka Dec 27 '10 at 15:03
Oh, right. Well, Grub 2 is getting way to weird for my tastes, so I switched to extlinux (part of syslinux package), which also now does support ext4. It's simple and straightforward to install. It just works. syslinux.zytor.com/wiki/index.php/EXTLINUX – Keith Dec 27 '10 at 20:57
I've just sent him the link to extlinux. – Maciej Piechotka Dec 28 '10 at 12:20
