Hi: I am trying to install 18.10 on an old Apple MacBook Pro. I made the mistake of upgrading a previous 18.10 installation to 20.10 and 22.04. The last upgrade confronted me with unsupported nVidia driver issues. I decided to go back to 18.10 but somehow lost my uefi boot capability. I installed OSX Leopard, the version that came with the machine (I said it was old) and that works, but I can't simply install ubuntu from the live-dvd because I can get it to boot into uefi.
Here is my Boot Repair pastebin URL: https://paste.ubuntu.com/p/FDzrY7syhH/
Any help would be appreciated.
Thank you,
Peter
