I've installed Ubuntu 12.04 on a partition with BTRFS as its file system, but it appears that grub2 seems to have some issues with that file system. For some reason it takes it very long time to boot and it doesn't display OS-selection screen at all.
So I decided to move my /boot
to a separate partition with ext2 file system. But I don't know what steps exactly should I take to do it. Please, help! :)
