Title:
  Thinkpad X120e (UEFI, AMD64) Won't Boot After Update

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  System asked to apply 'partial updates' updates to X120e today, which
  included some Grub2 items. After updates were installed, I rebooted
  system as requested and was asked which devices the boot loader should
  be installed on. Following advice in the help, I selected all devices.

  However, system failed to reboot. Got black text screen with the following on it:
  error: invalid arch independent ELF magic.
  grub rescue> _

  This is the third time this has happened to me. First time was a month
  or so ago. My X120e with 11.04 on it asked to apply updates. System
  would not boot after updates were applied.

  Re-installed 11.04 that evening, including reformatting the disk.
  System had same problem, and would would not boot because of the 'ELF
  magic' error.

  Re-installed 11.04 yet again. This time, when asked to apply the
  partial updates (no, I don't know why it asked for a partial update),
  I looked at the packages that I was being asked to have installed. De-
  selected Grub2 updates (no, I did not note which ones it was asking
  for). Updates applied, system reboots normally and operates without a
  problem for about a month.

  Two days ago, I was asked to apply partial updates again. Today, I
  decided to let Update apply everything it wanted again, but 'ELF
  magic' issue occurred again.

  The X120e is configured to boot with UEFI. My home directory was
  encrypted - an install option. AMD64 install.
