So to update. The install finished perfectly. I rebooted. Now I’ve got a flashing question mark folder.
I presume the Mac uEFI can’t find the Linux install or doesn’t know what to do with it.
Here are some instructions for resolving the same situation with Ubuntu. Going to see if I can get a Live USB drive working and see if I can do something (don’t know what exactly) working for SangomaOS
So you installed a release of the OS that is EOL and unsupported? Granted it went EOL a couple months ago but it’s still EOL. Why didn’t you do this with 16.04 or 18.04 which are LTS and have support to at least 2021 or 2023 (depending on the version).
Thanks Dicko. Fun is not exactly the word . Yesterday I was so frustrated I nearly threw the bloody Mac out of the window. Today is a new day.
I’ve come across rEFInd on my quest too, but I don’t think it will help if SangomaOS has been installed as GPT instead of MBR. I may well be wrong on this. I am working pretty blind here!
I’m thinking my best bet is to reinstall Ubuntu 14 (sorry Tom!!) and then try to see if I can overwrite (but keeping the individual partitions intact?!) it with SangomaOS - really not sure if this will or can work but it seems like my last hope.
