Title:
  natty wubi install shows grub shell after update

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  Updated my existing wubi natty install and on reboot, it dropped to a
  grub> shell

  Managed to manually boot using linux=/boot/vmlinuz...  root=/dev/sda4
  loop=/ubuntu/....root.disk

  i use sda4 because ubuntu is installed on the 4th partition of my hard
  drive. (1st is recovery, 2nd is boot loader, 3rd is C drive and  4th
  is d: drive)

  i then ran update-grub once the system booted up.

  That seemed to go ok since it picked up all entries nicely.

  After reboot, this time when i selected ubuntu in the windows boot
  loader, two or three lines of grub shell quickly appear and the
  computer reboots. I think i found the problem though.

  I booted a lucid liveusb so that i could examine what was in
  grub.cfg.

  I notice all the entries with the lines:

  set root='(/dev/sda,msdos4)'

  appear to be wrong. it seems kinda confused to be either (hd0,4) or  (/dev/sda4)
  so anyway i replaced all those /dev/sda,msdos4 entries with /dev/sda4 and the system booted without issue.

  So i guess that should be fixed.
