Linux is the best operating system around, since, actually, it has been around.

Nowadays, it oscillates between straightforward to tricky (especially if you pick up hardware with one piece of setup that is not supported).
I like kubuntu (mainly because I like KDE).
This page details the process. This is most easily achieved from the command line:
sudo dd if=Downloads/kubuntu-21.10-desktop-amd64.iso of=/dev/sdd conv=fdatasync
