I added the output to the original post. ** Description changed:
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.
