Today all of the sudden my laptop EliteBook 840 G3 with Windows 10 and Ubuntu 19.10 didn't start up anymore. Instead it is stuck in a infinite loop. Right after the HP logo shows up I get the error message:
"System BootOrder not found. Initializing default. Reset System."
It seems like I am not the only person around having this issue. But i tried several solutions and none of them worked for me so far:
This solution doesn't work for me because I can't unlock few more options. Turning on "secure boot" doesn't unlock any more.
This solution didn't cause any error messages on the way but also didn't solve my problem.
My third try was to follow this wiki article. But I had some error messages on the way. Maybe you could have a look at my console? It fails because it cannot open /boot/efi/EFI/ubuntu/grubx64.efi. Even when I switch into the directory it can't list the ubuntu directory. This seems weird to me.
Does anyone has a clue what I am doing wrong or what else is going wrong there and how I could fix this problem?
