[Bug 797544] Re: grub2 waits forever for keystroke before booting default OS. headless server. hang.

[Alecz20]

Just to follow-up on my last comment.

I was unable to try the solution as grub would not see the Linux OS after a grub-install on /dev/sda, and omitting to run update-grub right afterwards.
I struggled with a live-USB to fix grub, but after several hours, I ended just re-installing the whole thing.

After the new install the issue no longer appeared.

I guess there is something flaky in the code that causes the issue to
only appear on occasion.

Title:
  grub2 waits forever for keystroke before booting default OS.  headless
  server. hang.

Status in “grub2” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: grub2

  After a seemingly-routine "apt-get update" on an Ubuntu 10.10  server, the machine hangs on boot. 
  It is sitting at the grub2 prompt, waiting in vain for someone to come along and press <enter>.

  I have tried two workarounds:

  ---------------------------------------------
  Edit /etc/grub.d/00_header to remove the check for recordfail in:

  make_timeout ()
  {
      echo "set timeout=1"
  }
  --------------------------------------------------------------------
  In /etc/default/grub set
   GRUB_HIDDEN_TIMEOUT=2
  ---------------------------------
  Then "sudo update-grub"

  Now I'm pretty dang stuck.  There is plenty of forum activity on this
  issue, but no true solutions.
