Comment 39 for bug 1798171

Update:

I copied mmx64.efi from /efi/boot on my hard drive to the same location in the iso.
I now receive the below warning and system attempts to bootloop forever:

System BootOrder not found. Initializing defaults.
Creating Boot entry "Boot0002" with label "ubuntu" for file "\EFI\ubuntu\shim64.efi"
Reset System

I searched this error message and found this:
https://askubuntu.com/questions/1042747/system-bootorder-not-found

but since I have a Lenovo this BIOS looks different and I am unable to find "Select an UEFI file as trusted for executing"

Once again, if anybody has any solutions it'd be great :)
