A different take. Trying to get fancy here with dual booting, virtual machines, etc. is risking trouble. It can get really bad, read the whole thread referenced at the end of this.
I built a PI processing machine with a Threadripper. The system was clean and new. I loaded Ubuntu 18.04LTS, as mainstream as it gets. Then PI. And I was immediately processing. My PI benchmark was near the top of the charts. Simple has considerable virtue. _Especially_ if this is your first Linux experience.
I have another machine I use for Windows 10, and general work. The only other thing I do on the PI machine is PI, Internet browsing/downloading PI updates and other things relevant to PI processing.
You _really_ don't want to go here. This guy has spent many frustrating hours on this, and still isn't processing. As I said there, he might more profitably have just used Windows. There's no real advantage to using one Linux distro over another, once you're running PI, it _really_ doesn't matter.
