I installed an Ubuntu 14.04 LTS on an HP ProBook 5320m
Now, when I boot the system the machine says invalid boot device. When I press F9 and point the boot EFI file, I can boot the machine fine.
I tried already to change the boot order, looking at the HD first, no difference.
Unfortunately, I can't save the EFI file to boot, so I guess I should update the partitions somehow.
I tried already boot-repair, but it just has copied a fresh EFI file for loading Grub.
What can I try?
