    Your Operating System that you are using now is just out of support just until this April 2021. But maybe other here in the community might consider helping you if they already encounter same problem as you do.
    But then again, just want to remind you that your Operating System is already out of support right now. so, just wanna make you understand it. Good Luck.

    what kind of information did you need ?
    Run boot repair with the Create Bootinfo Summary option and post the link you get when it finishes. That will have the information needed for someone to help.

    System not that old as it is UEFI.

    Report did not show some info that is normally in / like grub.cfg & fstab.
    You have to mount lvm & decrypt install before report or repair.
    But repairs will not work as repository for 16.04 is closed. EoL 21-04. The LTS versions are only for 5 years.
    (actually surprised Boot-Repair worked at all as it is only for current versions of Ubuntu).

    Do you have good backups?
    With encryption that is a requirement.
    And if not, that is the first thing you need to do.

    oldfred is asking if you have back-ups of your data.

    If you do not have back-ups, then that is your first priority.

    Boot-repair will not fix your boot problem because you are using Ubuntu 16.04, which is unsupported.

    When you have back-ups of your data, you should install a supported version of Ubuntu i.e. 20.04 LTS (Long Term Support)
