So I installed Pop OS on an old mac book air. Then I decided to wipe it off and install Lubuntu. However I could never find the bootable USB with the lubuntu iso in my boot menu. I know that pop os isn't using grub and instead the systemd init system. I don't know, however, if this has anything to do with it.
I then installed the boot-repair tool and made somechanges and rebooted it again. Now I'm stuck in Grub telling me that:
Failed to se MokListRT: Invalid Parameter
...
I can do an ls and get the following
(proc) (hd0) (hd0.msdos1) (hd1) (hd1.gpt4) (hd1.gpt3) (hd1.gpt2) (hd1.gpt1)
Within the hd0 I can list
efi/ loader/ and some hash-like number
Within efi I can then see
Reovery-7DD.../ POP_OS... systemd/ boot/ Linux/ pop/
It's just that I'm really list here. In first place I don't know why I could never find my bootable USB (I always just saw Pop OS and Pop OS recovery when hitting F7 when starting up). And now I'm completely lost.
I know there is this answer Stuck at GRUB command line, but still I'm not really making progress. I'd be thankful for any pointer to anything
