I have a MacBook Pro set up to triple boot with rEFIt and GRUB. (I had to go through GRUB to get Windows 7 to boot, but that's tolerable.) I upgraded to Lion which added a new partition for the recovery feature. This also causes GRUB to boot to a rescue prompt. Running set shows:
If I run the following commands:
set prefix=(hd0,gpt6)/boot/grub set root=(hd0,gpt6) insmod normal normal
the usual GRUB menu shows up and I can boot into whichever OS I want. I got into the Ubuntu partition and checked out the
grub.cfg file and it was setting the root to gpt5. I ran the
sudo update-grub command. This changed the value in the cfg file to gpt6. However GRUB still boots into the rescue prompt and set still shows the initial root and prefix values. How do I make this permanent?
