Title:
  grub failed to install to /dev/sda on retry

Status in “grub-installer” package in Ubuntu:
  Triaged

Bug description:
  Precise Desktop i386 20120423

  TEST CASE:
  1. Start a live session from a usb stick
  2. Start ubiquity
  3. Select the manual partitioner
  4. '/dev/sdb' (installation media) is selected by default (bug 987418) if it is not, select it (grub will fail to install at the end of the installation, this is expected and the objective of this test)
  5. Continue with the installation 
  6. At the end of the installation grub fails to install to /dev/sdb and a prompt is displayed to select another device
  7. Select '/dev/sda' and validate

  EXPECTED RESULT
  grubs installs to /dev/sda

  ACTUAL RESULT:
  This crash. On reboot the user is dropped to a grub shell
