I am stuck with a rather irritating problem I ran into after installing 11.10 on my macbook pro 5,5.
I did a clean install efi booting into the setup using the desktop cd. Upon the first reboot I was presented with the "invalid arch independent ELF magic" and grubs rescue console.
I have read GRUB: "invalid arch independent ELF magic" after install on SSD but the solution is no solution for me since installing grub via live cd only means installing the mbr version and I can't seem to find any manual on how to install grub-efi while booted into the live cd.
So my question is: How can I either edit the grubx64.efi file in my EFI Partition, reinstall grub-efi with a live CD / DVD or use grub rescue commands to fix this issue?
