Public bug reported: I ran a test install of ubuntu2104 after which I ran an update in the installed system and files related to grub-efi were upgraded. I later removed this installation during a re-install. The files on my installation media relating to grub-efi would have been older than those actually installed in the boot on my pc. I think this probably caused the crash. If I get the latest version of the beta [is that possible?] I don't think there would be a problem. I did actually manage to install but got a warning there might be problems.
