Would like to confirm this bug, I recently experienced the exact same
error when trying to boot a Windows8.1 install from grub menu. My Linux
Mint 17 continued to boot normally.

I attempted to remove/reinstall grub with all defaults etc.. no change.

I found in my update history updates of 6 x grub packages firstly from
1.3 to 1.6 and then from 1.6 to 1.7 on January 6th.

grub2-common
grub-common
grub-efi
grub-efi-amd64
grub-efi-amd64-bin
grub-pc-bin

I rolled back to 1.3 using files in /var/apt/cache/archives and presto,
Windows boots just fine again. Updated to 1.6 and Windows still boots.
Updated to 1.7 and it breaks again with exact same error as reported in
this bug.

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:
  Confirmed

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
