Thanks for this tutorial, I too run into Grub 2 trouble after updating my Ubuntu (even when I deselect the new kernel, which seemed to cause the problem at first).
I need a little help figuring out which harddrive to install grub to, because I have an unusual configuration.
I use Wubi to install Ubuntu, and I can't switch to a physical partition just like that because I'm using a MacBook Pro.
Before Grub2, Wubi was the ideal solution to have a triple-boot system (Mac OS, Win XP, Ubuntu) without having to replace Apple firmware with rEFIt and manually creating partitions in the terminal and what not.
So what I know is that on this Mac, sda1 is where EFI resides, sda2 is where Mac OS X is installed and sda3 is the Windows partition. So I think I don't wanna install grub to sda or sda0, because that'll screw Apple's EFI and partition-table etc.
So can I just do this?
If not, how would I go about figuring out where Wubi installed Grub 2? Is it in a config-file? Is it in the load-letter?
sudo grub-install /dev/sda3
Thanks so much for the help in advance.
