[Bug 1311247] Re: error: malformed file, press any key to continue

[luvr]

I also got this error, but now it's gone.
I have Ubuntu 14.04 installed on my /dev/sdb3 partition, and the GRUB2 boot loader is installed on the boot sector of the partition (not on the Master Boot Record).

The problem disappeared after I did the following (though I'm unsure if
that's what made it disappear; for all I know, it could be sheer
coincidence):

Booted Ubuntu 14.04. Got the error, but the boot completed OK.
Ran the following three commands (as root, i.e., after I issued the "sudo su -" command):

grub-install --force /dev/sdb3
grub-install --force --recheck /dev/sdb3
update-grub

Rebooted Ubuntu 14.04. Still got the error, but, again, the boot completed OK.
Repeated the very same three commands.

Rebooted Ubuntu 14.04 one more time.
The error was gone.

So far, the issue hasn't returned.

Title:
  error: malformed file, press any key to continue

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  I have just upgraded from 12.04 to 14.04

  Since the upgrade, when I boot up, the process stops and the normal
  grub screen is replaced after a short while by a message saying

  "error: malformed file, press any key to continue"

  Pressing a key allows booting to continue.

  Someone else who experienced this found that the problem went away
  after having re-installed grub.  I tried this but this did not resolve
  the problem for me.

  synaptic reports the grub package as 2.02~beta2-9
