YouTube!

I would 100% start by dual booting Linux Mint or KDE Neon alongside your windows install. Mint is more like windows, Neon is similar but has tons of configuration options so can be a bit much. Either will do you well though.

You can see reviews of both on YouTube to see how they look, and also watch some instructional on how to install a dual boot system. You’ll end up with Linux and windows both on your PC and you can pick which to boot at each start. That way you can go back to with does to get stuff done or checknon things while you’re learning.

Lastly, just be aware that things do work differently. That’s the good bit though! If you’ve used a Mac before you’ll be familiar with Linux already. The big differences are in how the file system works and how programs are installed. Again, YouTube will help you to figure those out.

Taken it slow, learn what does what and why, and you’ll be up and running in no time :)
