[Bug 1315978] Re: upgrade 13.10 to 14.04 moved grub to MBR

[Guus Geluk]

Addition maybe relevant:

After I got the upgraded partition  to start, I noticed that Windows7 no
longer was in the Grub menu. So I launched the app "Grub customizer".
Saving Grub however did not correct this. I then noticed that according
to "Grub customizer" Grub was not in the MBR, so it saved it to the
partition. After choosing "install in MBR" the problem was solved.

So it seems that even though Grub was installed in MBR, Ubuntu itself
was not aware of that.

Title:
  upgrade 13.10  to 14.04 moved grub to MBR

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  I upgraded from 13.10 to 14.04 via the update manager. Before upgrade
  Grub was in the Ubuntu partition and I booted Grub via the windows7
  bootmenu (modified with EasyBCD). During the Upgrade grub was
  automatically installed in MBR. After reboot it showed Grub, but
  choosing Ubuntu, it did initialize a start (Screen changed) then
  stopped. (Windows worked fine). I noticed however there was no disk
  activity at all. So I suspected something wrong with the Ubuntu Grub
  entry. I then installed 14.04 on another partition with the live.iso
  on USB, Grub was renewed in the process, and then the upgraded
  partition did start and all was well with the upgrade.

  Expected behaviour: Keep Grub in the Partition or move it to the MBR
  after asking. If allowed to move Grub to MBR, it should at least work.
