I have a separate 10GB partition to test pre-release builds. This time I decided to test the btrfs as root. After finishing installation, ubiquity showed an error message stating that grub could not be installed and I must install it manually. I thought 11.10 supported grub on btrfs. Anyways, here is my partition scheme.
/dev/sda1 ext4 / (Oneiric) /dev/sda2 ext4 /home /dev/sda3 btrfs / (Oneiric)
The problem is that grub does not pick up /dev/sda3 entries using update-grub2 command.
How do I manually add an entry for /dev/sda3 to grub2 so that I can choose which installation to boot into?
