Lots of tutorials available. I find it has gotten much easier over the years. The new installer is very good, but I just upgraded. So many benefits, I never looked back from windows. Much faster and more secure. Never worry about malware. All the apps are also opensource and update automatically. No worry about licenses. Just create another partition, and leave the old one in case you want to boot back to windows for any reason. Even Microsoft is supporting Ubuntu/linux now.
