[xubuntu-users] Grub breaks after kernel 3.5.0-23

[mikeossur at altoonawa.org]

Hi Tim, Ralf,

Thanks for your help!

http://www.supergrubdisk.org/super-grub2-disk/ worked like a champ and I 
am back up and running.

When I try and do this  sudo grub-install /dev/sda

I get this.   -- Am I being stupid here? Am I missing something?

/usr/sbin/grub-bios-setup: warning: this GPT partition label contains no 
BIOS Boot Partition; embedding won't be possible.
/usr/sbin/grub-bios-setup: warning: Embedding is not possible. GRUB can 
only be installed in this setup by using blocklists. However, blocklists 
are UNRELIABLE and their use is discouraged..
/usr/sbin/grub-bios-setup: error: will not proceed with blocklists.
