[Bug 756564] Re: After Maverick to Natty upgrade, grub won't boot and displays "symbol not found : 'grub_env_export'"

[pureblood]

I had the same problem. I think what is happening is that grub 1.99 is not installed in the mbr. Not sure why. Does it say grub 1.98 on your grub console? I fixed the problem with the following command lines:
sudo apt-get purge grub-common
sudo apt-get install grub-pc
After booting the system from grub 1.98 with:
linux /vmlinux root=UUID=877e3558-6ecf-4908-818f-b0369b692834
initrd /initrd.img
boot
Notice that the UUID might not be the same in your system.

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")
