If you’re really not sure and don’t want to break anything, I’d suggest installing some different OSes in virtual machines and try on that first. That might be a learning curve by itself, but you won’t take your computer as hostage for your beginner’s errors.
There are more user friendly OSes than others. I’d go with a Ubuntu or *buntu flavor just for the fact that there’s a lot of beginner friendly websites, tutorials and forums.
