Post-install boot loop: "System BootOrder not found."

[Alexander Dietrich]

Bionic Beaver Final Beta doesn't install properly on my computer (Thinkpad E480 with an NVMe SSD, no SATA disk). After finishing the installation, the machine repeatedly shows these messages and reboots:

System BootOrder not found. Initializing defaults.
Creating boot entry "Boot0000" with label "ubuntu" for file "\EFI\ubuntu\shimx64.efi"
Reset System

This happens both with automatic and manual partitioning. Setting the "UEFI/Legacy" switch in the BIOS to "Both" or "UEFI Only" also doesn't make a difference. (The installer doesn't boot at all when choosing "Legacy Only".)

I checked the EFI partition and the file "\EFI\ubuntu\shimx64.efi" does exist.

I found the reason for this problem: it turned out to be the BIOS setting "Boot Order Lock". After disabling it, I saw the above message one more time, then Ubuntu started properly (and a new boot entry called "ubuntu" appeared in the BIOS).

I don't know if this is possible, but it would be a good idea to detect that the "ubuntu" boot entry wasn't actually created and display an error message. If it's not possible, an additional hint about "Boot Order Lock" or similar BIOS settings might be helpful (as well as showing the message for more than a split-second).

Sadly, I looked into that already, and we don't have that option: the firmware does not let us know that it really didn't create the entry.

Closing as "Invalid" since the issue was reportedly fixed by disabling Boot Order Lock.
