Comment 5 for bug 525085

Getting the same error when installing Lucid Alpha 3 Server amd64 using a cd image downloaded 2010-03-16 on a server with the root/boot filesystem on a RAID 1 setup using software raid.

After 3 unsucessfull attempts, I let the installation "Continue without installing the boot loader". I then rebooted to the install CD again, and chose rescue mode so I could get a shell. When I got to the shell, I tried to run grub-install --no-floppy --force /dev/sda, and got an error saying the filesystem (ext3 in my case) does not support UUIDs. Did some research, and apparently, installation should have chosen to install the old grub version instead of grub2.

So, using aptitude, I removed (purged) the grub-pc and grub-common packages, installed grub (and all uninstalled required dependencies), ran grub-install, then ran update-grub.

I'm now able to boot the system properly.
