I have a dual boot, W10 and Ubuntu 16.04. Each OS is installed on a HDD. Very often, when I quit Ubuntu or update W10, my GRUB partition is erased and I have to use boot-repair to make things back together.
Today I had the same problem after shutting down Ubuntu (properly), but there was no update from W10 nor Ubuntu. After rebooting my computer, I only had a GRUB shell. I used boot repair as usual, but now My only option in GRUB is :
EFI/ubuntu/fwupx64.efi
EFI/ubuntu/mmx64.efi
System Setup
When I choose first option, nothing happen.
When I choose second option, a blue screen named Shim EFI key management
ask me if I want to perform a MOK management.
My boot is UEFI.
I added a boot sequence for EFI/ubuntu/shimx64.efi
and even EFI/ubuntu/grub.efi
, but all I got is the same 2 options
/dev/mapper/ubuntu--vg-root: clean, XXX/XXXx files, XXX/XXXX blocks
