What?  That didn't make sense.  Can you go into your bios and try to
change the boot order there?  It looks like it is buggy and refuses to
accept the boot configuration and will only boot the hard drive like it
is a removable media.  You might try deleting the Boot directory on your
EFI system partition and see if that helps ( but keep a copy of it
somewhere else so you can put it back if the system becomes unbootable
).  Otherwise, the only thing for it is to copy ubuntu/grubx64.efi to
Boot/bootx64.efi and complain to the manufacturer about their broken
firmware ( or better yet, return it for a refund and buy from someone
who doesn't use broken firmware ).  This is what boot-repair did when
you used it before, and after updating grub, the copy is now out of
date, hence the error.

Title:
  Selecting grub entries (efi) at boot time leads to "error: symbol
  'grub_efi_find_last_device_path' not found"

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  1. Situation

  1.1 I installed Ubuntu 14.04 on an OEM "Windows 8.1" laptop more than a year ago
  1.2 Ubuntu installed grub to manage OS selection
  1.2 The last automatic software update of Ubuntu (09.01.2016) updated grub (see https://bugs.launchpad.net/ubuntu/+source/grub2/2.02~beta2-9ubuntu1.7) 
  1.3 Since then selecting grub menu items to start windows produces the following error message

      "symbol 'grub_efi_find_last_device_path' not found"

  1.4 Reverting back to https://bugs.launchpad.net/ubuntu/+source/grub2/2.02~beta2-9ubuntu1.6 solves this issue
  1.5 Retrying to upgrade from 2.02~beta2-9ubuntu1.6  to 2.02~beta2-9ubuntu1.7 reintrocudes the issue  

  2. References 

  2.1 Output of

          dpkg --list | grep grub

  2.4 Reverting to grub 2.02-beta2-9ubuntu1.6_amd64 

  Steps:

  1. Download the following files in a separate (newly created) folder

  grub2-common_2.02-beta2-9ubuntu1.6_amd64.deb
  grub-common_2.02-beta2-9ubuntu1.6_amd64.deb
  grub-efi-amd64_2.02-beta2-9ubuntu1.6_amd64.deb
  grub-efi-amd64-bin_2.02-beta2-9ubuntu1.6_amd64.deb

  2. From that folder install the deb files with the following command:

  sudo dpkg -i *.deb
