    If mokutil is not installed on your Ubuntu Desktop LiveCD... Install it and ...
    Code:
    sudo apt update
    sudo apt install mokutil
    mokutil --sb-state
    Tell me what it said on the last command...

    Yes, theres no secure boot option anywhere. No, it mentioned curl and pastebinin weren't installed, but I installed them and it seemed to run fine

    So the command
    Code:
     mokutil --sb-state
    returned

    Code:
     This system doesn't support Secure Boot

    Re: Cannot get my Lenovo H520S to boot to Ubuntu Server 20 LTS

    For some reason (I am the author of the Forum's system-info script), my script skipped reporting that in the report... That command is in there and should have shown up right after the other BIOS information in that report... Dang, I'll debug that later. LOL

    And there is a confirmation of the problem... Both the install and Boot-repair misread something. If you look at all the boot-repair reports, it installed grub-efi-amd64 signed and configured it as if it was... well here is what it used for a command (you will see it yourself)...
    Code:
    grub-install --efi-directory=/boot/efi --target=x86_64-efi --uefi-secure-boot
    You reinstalled with LVM again right?

    Post the results of these and I will talk you through it manually...
    Code:
    fdisk -lu
    pvscan
    vgscan
    vgchange -a y
    lvscan

    Haha if it helps I saw the "This system doesn't support Secure Boot" come up somewhere as the script was running XD.

    I believe I did reinstall with LVM, I left everything as default which I think puts it in an LVM

    To help me debug that script... You say it showed up when you viewed it in 'less'? But somehow when it prepared the written report, it skipped over it in and didn't include it... Hmmm. That was an important key to your problem. LOL

    As soon as I get that info from those commands, which has a litle different output for the LVM names, then I will post instructions to mount the filesystem of your installed, chroot into it, to purge the signed version and install the regular EFI version of grub.

    So the fdisk -lu one might be a struggle to copy out.

    pvscan

    Code:
    /dev/sdc: open failed: No medium found
    PV /dev/sda3 VG ubuntu-vg           lvm2 [<464.26GiB / <264.26 GiB free]
    Total: 1 [<464.26 GiB] / in use: 1 [<464.26GiB / in no VG: 0 [0    ]
    vgscan

    Code:
    /dev/sdc: open failed: No medium found
    Found volume group "ubuntu-vg" using metadata type lvm2
    vgchange -a y

    Code:
    /dev/sdc: open failed: No medium found
    /dev/sdc: open failed: No medium found
    1 logical volume(s) in volume group "ubuntu-vg" now active
    lvscan

    Code:
    /dev/sdc: open failed: No medium found
    ACTIVE                    '/dev/ubuntu-vg/ubuntu-lv' [200.00 GiB] inherit
