Only "systemd-boot" or "grub2-bls" are recognized (end of dup)

I think that it was because of my attempt to install via Legacy BOOT *USB Storage Device and not UEFI BOOT USB PMAP (now shown as opensuse-secureboot) when pressing f12 during machines POST.

Summary        : bootctl wrapper for BLS boot loaders
Description    : 
    bootctl wrapper for BLS boot loaders, like systemd-boot and grub2-bls.
    Implements also the life cycle of a full disk encryption installation,
    based on systemd.

I think this was occurring due to me attempting Legacy Boot < USB Storage Device < openSUSE installer. More info above if interested. You can tell secureboot openSUSE boot is working correctly by displaying DELL symbol with Tumbleweed displayed at the bottom of head/display after LUKS key is opened.

Contain a bit of information about BLS boot loaders here in post maybe…

Found out why, it’s there because I was running SELinux.

You wrote them you have installed “sdbootutil”, but you didn’t notice you HAVE NOT it installed!!

Sorry for the mistake about this. Thank you for pointing that out.

I do not know why the bug report link above disappeared above (perhaps I didn’t paste it correctly). I do not know enough about the process as to what will happen next.
-Thanks
