[Bug 356584] Re: Upgrading from grub to grub 2 in ubuntu 9.04 raise this error: Error 11: Unrecognized device string

[Luis Ochoa]

This was because when you update from legacy grub to grub2, there is a
transition time where machine starts with legacy grub, but you can start
grub 2 chainload, to test everything goes fine, but in my case everything
goes wrong and ubuntu doesn't start with Error 11: Unrecognized device
string, to fix it as I wrote before I just change my list.conf for this
transition time and after I change:

uuid        cfe6c165-8b52-48d4-9533-0323e2ef67c6
to
root (hd0,1)

Everything goes fines, start ubuntu again throught grub 2 and then I run
upgrade-from-grub-legacy command from my root terminal to finish upgraded
from grub legacy to grub2 and menu.lst is never used again.
