Hello!
I'm interested in moving my personal computer to running Linux but I'm not sure where to even begin. As background, I am a casual user and have a desktop with hardware from around 2014 running Windows. I am hoping to setup a NAS drive as a media server in the next year or so, offloading all of the files currently on the Windows desktop and have been interested in open source software such as Jellyfin. I also mostly game on an Xbox and Nintendo Switch, but have used the desktop in the past for gaming such as with an Oculus Rift Headset and some Steam games so not huge on getting games working on the computer. But, I do sometimes torrent using the computer so don't want to lose that capability (especially with upkeep for the media server).
With all of that said, I didn't know how to get started with choosing what Linux OS to use, setting it up, backing up my files to make sure I can use them with the new OS, etc. Making the switch seems to have great options for customization and "choosing a distro that works for you", but I don't know what would work for me or what will be user friendly for a beginner.
Any tips or pointing me in the right direction would be greatly appreciated! Thank you!
It doesn't really take long to get the basic stuff figured out though, but there is definitely that initial feeling of being lost. As others have suggested, start out running something in a VM on your Windows desktop, then you can quickly go back and forth to practice doing things in linux as you have time (plus it's a huge benefit to have a working browser in Windows so you can do a search if something breaks).
Linux has a number of different desktop environments to choose from, and what's cool is you can load up multiple types and select one at the login screen. If you want to start with something that is reasonably comfortable, try loading the 'Mate' desktop. Maybe I'm just used to old-school Windows (Win2K was the last one I used), but I've always thought Mate did a good job of putting all everything in logical places. As for the OS itself, there's also been a lot of suggestions so I'll throw mine in as well... I'm a die-hard Debian fan, both on my desktop and on my servers. It does NOT push bleeding-edge releases on you, so this means you won't have the very latest updates but to me it's more important to have a rock-solid system that I can always rely on. I've been using it for about 15 years now and it has never failed me.
Do others auto-update or are users prompted as updates become available?
On the desktop you will likely be notified when updates are available. On my servers I do automatic security updates, but leave the rest for manual updates so I can do one machine at a time and know right away if an update breaks something.
