Install of the boot loader failed

[Stephen Russell]

I was running Ubuntu 18.04 which was working fine. I attempted to update to 20.4. The update failed miserably (many panic messages)and the automatic recovery to 18.04 failed also. I then ran Ubuntu 16.04 from disk, which worked, but would not install. I ran "boot-repair" which also failed (exited). I created a new disk image of 18.04 which seemed to install and I am using it to send this message, but grub-installer would not load on any of the Ubuntu partitions on my hardware. I will need to manually install a boot loader and I have no idea how to do that. Please help, else this machine will become a Windows 7 machine and I do not have any use for that OS.
