Description Tomas Kindl 2013-12-08 13:59:47 CET 
Description of problem:
After reinstalling grub2-efi, system failed to boot. Culprit is that efibootmgr failed to write EFI variables so entries can be deleted but not added and sometimes updated.

To fix this you must use EFI/BIOS to add bootloader again which is nontrivial for users.

Device: ASUS VivoBook S551LB.207

dmesg snippet:

[56413.895611] efivars: set_variable() failed: status=8000000000000009
