I'm running Ubuntu 12.04. I installed Ubuntu from USB using the 64-bit iso.

After realising my graphics card was not properly supported in EFI mode I tried to switch from grub-efi to grub-pc.

I ended up not being able to access the grub menu. Output from boot-repair is shown below:

I discovered that I could boot Ubuntu from a grub-recovery cd using the following commands:

set root=(hd0,4)
linux /vmlinuz root=/dev/sda4 ro
initrd /initrd.img
boot

Does anyone know how I can get grub to boot off my hard drive?

Im more interested in your graphic issues with macbook and EFI, since this works fine for me :) also I believe efi is the way to go with mac :) what macbook / gfx card do you have? – tomodachi Apr 24 '12 at 22:45
I have a Macbook 7,1 and an Nvidia 320m. Under EFI mode: The nouveau drivers work fine, but the NVIDIA drivers end up switching off my display during booting. My graphics card produces too much heat when I'm using the nouveau drivers. It doesn't seem to fall below about 75°C when idling. – David Apr 25 '12 at 7:11
Update: I was installing grub to the partition, instead of the overall disk. I've got my computer to boot successfully now. Thanks for replying tomodachi. – David Apr 25 '12 at 15:26
