[Bug 970464] Re: Grub menu flashes and disappears

[Ajoy Bhatia]

I am stuck with the same issue. In my case, I had Windows 7 on one
partition and Ubuntu 11 on the other, and grub menu selection worked
fine. After I updated Ubuntu to 12.04 LTS (Precise Pangolin), I have the
same problem. Tried Boot-Repair, pressing Shift and Esc keys, changed
timeout to 10 and then -1 in /etc/default/grub. No change in behavior.

Title:
  Grub menu flashes and disappears

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  A test netbook had Windows 7 and Kubuntu 12.4 on it.
  A fresh install of ubuntu 12.4 has replaced Windows 7.
  Grub2 now only flashes briefly and loads the default OS

  Both OS have the same name in Grub, but are on different partitions
  (sda1 and sda8).

  Repairing Grub, un-hiding the menu, setting a long timeout, pressing
  keys, nothing works. The only way to switch OS is to edit the boot
  menu.
