Title:
  grub-efi update causes "Operating system not found"

Status in “grub2” package in Ubuntu:
  New

Bug description:
  This bug probably only affects laptops with immature efi implementations.
  The uefi-bios of the lenovo x325 has a problem with the efi file structure of grub-efi. After the latest grub-efi update it would not boot but only displayed "Operating system not found". I fixed this by moving the grubx64.efi file from /EFI/ubuntu to EFI/BOOT and renaming it to: BOOTX64.EFI
  This was proposed at: http://www.rodsbooks.com/efi-bootloaders/installation.html
  I also tried using an efi startup script called "startup.nsh" containing just one line:
  fs0:\EFI\ubuntu\grubx64.efi
  I put this directly on the efi partition. However this alone did not work.

  Ubuntu and package info:
