Today when I went ahead with Natty installation I had selected btrfs
for root
filesystem. To my utter surprise I was presented with the screen
Unknown filesystem
grub rescue >
None of the options I tried like Y
, yes
did not work. Later I again installed Natty with ext4
filesystem.
Why do such errors appear?
Best Answer
btrfs
is considered experimental and unless you're very adventurous, you should avoid using it. There is neither a fsck tool available in case thebtrfs
filesystem becomes corrupt (after a power failure for example).An excerpt from the release notes:
GRUB can actually boot from btrfs filesystems (instructions), but note that Ubuntu still consider btrfs as experimental.
