So, I got the idea to take an old PC with no OS and turn it into a dedicated BOINC machine. To save on costs, I decided to use Ubuntu 18.04 for the OS. I never used it before, so challenge accepted.
Below is the installation process I used. The difficult part was finding all the commands I had to run to install the graphics drivers (i.e. Nvidia).
Hopefully, this post will help anyone else or myself when I set up another BOINC machine.
NOTE: This process documents the bare minimum to get BOINC running on the machine. If there is anything else that would be useful to add to the instructions, please do so.
