Seriously, I once started out like you, no computer knowledge, nothing.
Then I heard about linux. I installed linux mint on extra room on my
SSD, and once got comfortable with the CLI, moved on to better distros
that don't suck or babysit you, like arch (i use arch btw). So if your
drive has some extra room, even only 50 GB, you should install a linux
distro. But not ubuntu. Never ubuntu. Ubuntu server sucks too.
