Hi,
After many many try, I have succeeded to boot into Ubuntu (latest LTS 16.04.6) after changing uuid value that I have saved before delete my HDD.

First step, but now I cannot repair bios...

I have installed fixed kernel but impossible to boot on it. I have changed grubx64.efi by http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/uefi/grub2-amd64/2.02~beta2-36ubuntu3.21/grubx64.efi.signed
It still blocks with the same error : vmlinuz invalid signature

I have also tried to update Ubuntu but nothing.

Thanks for your help.
