A path problem is only possible if there is some other GRUB installation
on the system.  Could you look for other .efi and .mod files?

Title:
  grub_efi_secure_boot symbol not found after update to grub
  1.99-21ubuntu3.7

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  On a working HP ENVY m4-1015dx system using UEFI without secure boot,
  the system is unable to boot into Ubuntu 12.04 from OS Boot Manager
  following update to grub 1.99-21ubuntu3.7. The grub 1.99-21ubuntu3.7
  menu appears correctly. However, selecting any ubuntu kernel generates
  the error:

  symbol not found: `grub_efi_secure_boot'.

  The system will boot successfully into Windows 8 from the same grub
  menu. The system also boots successfully to ubuntu from other BIOS
  boot options: Ubuntu (WDC ...) or Boot from EFI File and then
  selection of the file EFI/ubuntu/grubx64.efi. Either of these latter
  successful boot options produce a grub menu that appears identical to
  the earlier-mentioned grub menu, but these boot successfully. At least
  two other individuals using different hardware have reported analogous
  problems on the forums (ie. systems using UEFI but NOT secure boot).
  These problems may depend to some extent on the BIOS, but they do not
  appear to be unique to this particular hardware.
