Title:
  After Maverick to Natty upgrade, grub won't boot and displays "symbol
  not found : 'grub_env_export'"

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: grub2

  It's pretty much all in the title, but Grub2 messed up after the upgrade from 10.10 to 11.04. During the install, i watched carefully the configuration procedure, it ran fine.
  I then just rebooted, and there it was: grub simply said:
  error: symbol not found: 'grub_env_export'
  grub rescue>

  (btw: grub rescue doesn't even return me a help menu on "help")
