hello all,
after last kernel update I run into a grub error:
error 11
unrecognised device string
which sounds weird because I haven't messed with partitions at all before this
I`ve already tried to reinstall grub from live cd
sudo grub
find /boot/grub/stage1
root (hd0,1)
setup (hd0)
without succes.
I`d like to ask you to help me finding out what went wrong and how can I recover my ubuntu install.
