Okay,I give up. Hope someone else can help with this.
Let us know if you got this fixed (and how).
But good luck.
Can you tell me if this /etc/default/grub config works on your system,
or if you see any obvious reasons why I would receive an error while
booting? Any idea how to recover that boot error message?
