[Bug 926387] Re: boot failure after sudo update grub sudo grub-install /dev/sda

[jerrylamos]

Sure enough, boot was clobbered even though the console said "no error
reported".

This time I was able to successfully use the "Boot-Repair" CD.

Title:
  boot failure after sudo update grub sudo grub-install /dev/sda

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Time after time on this Acer Aspire 5253 cannot boot after doing sudo update-grub sudo grub-install /dev/sda
  All I get is a colored screen with four tiny little columns of black lines at the top.  Will not boot.

  Only recovery possible is to install into a different partition.
  Install fixes the boot but of course lists the new install at the top
  of the list instead of the precise pangolin I'm trying to test.

  So what I did was a sudo update-grub and a sudo grub-install /dev/sda
  as you can see in the console listing below.

  Then I did ubuntu-bug grub2 maybe someone can see how the boot record
  has gotten clobbered.

  I'll reboot, verify the failure, then I have to do a new install
  again! into a different partition to fix the boot.
