[Bug 1363719] Re: efibootmgr may create a duplicated boot entry, "breaking" UEFI boot.

[Moritz Heiber]

This is a really serious issue for anybody running/upgrading/installing
Utopic under UEFI.

Another way of working around this limitation is to install the package
from Vivid.

Boot the system from a live CD and use wget to get ahold of the packages
from Vivid:

# Needed for the newer version to work correctly
wget http://mirrors.kernel.org/ubuntu/pool/main/e/efivar/libefivar0_0.15-2_amd64.deb

wget
http://mirrors.kernel.org/ubuntu/pool/main/e/efibootmgr/efibootmgr_0.11.0-1_amd64.deb

dpkg -i libefivar0_0.15-2_amd64.deb efibootmgr_0.11.0-1_amd64.deb

Then run 'grub-update' (to make sure we have all the kernels accounted
for) and then 'grub-install /dev/sdX' (replace X with the number of the
harddrive you're using).

After that booting in UEFI mode should be working again.

PLEASE FIX THIS ASAP!

Bug description:
  Hey,
    the current version of efibootmgr has a small ordering bug that causes, at least on x240, a duplicated boot entry to be added to UEFI, breaking the boot - UEFI resets everything to default values, and you have to boot from usb stick to fix uefi entries. There is an upstream patch that fixes it, and it would be great if we could add it.

  Upstream bug report is https://github.com/vathpela/efibootmgr/issues/7
