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

[Joris Claassen]

I ran into the same bug on my Thinkpad 440s. Installing
http://packages.ubuntu.com/nl/trusty/efibootmgr 0.5.4 from trusty in the
live CD environment and adding the boot entry using

efibootmgr -c -d /dev/sda -p 1 -l '\EFI\ubuntu\shimx64.efi' -L 'ubuntu'

Works. :-) Hope this helps!

Title:
  efibootmgr may create a duplicated boot entry, "breaking" UEFI boot.

Status in “efibootmgr” package in Ubuntu:
  Confirmed

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
