Title:
  [Natty] Grub no longer boots after upgrade nvraid

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  After upgrading from Maverick Meerkat to Natty Narwhal, grub will no
  longer boot to any of my partitions. I am using Ubuntu 64 bit.

   I have managed to boot back into Ubuntu by replacing this line:

  set root='(/dev/mapper/nvidia_bfhaeede,msdos5)'

  with this one:

  set root='(hd0,5)'

  I thought maybe that grub would need to be updated, so I tried update-
  grub once I managed to boot, but still faced the same problem when I
  rebooted. I also tried reinstalling the grub and grub-common packages
  through Synaptic.

  Here is the result of fdisk -l

  james at james-desktop:~$ sudo fdisk -l /dev/mapper/nvidia_bfhaeede

  I will also attach grub.cfg. When I update grub, it is finding all the
  operating systems, and they appear upon boot. They just won't boot
  without editing at boot-time.
