Enshittification

Just download Linux Mint and don't look back. I knew I was done with Windows completely so I quit cold turkey. It forced me to learn how to use Linux instead of running back to a Windows partition. The only reason to dual boot in my opinion is if you need the popular CAD software, or the popular Digital Audio Workstation software, or software like photoshop. If you just browse and game, then you should be fine.

I believe Linux Mint is the oldest beginner distro so it has a wealth of forum posts if you ever have a problem. It also has a bunch of GUI progams included for getting stuff done without terminal, but make no mistake you will have to use the terminal to do stuff on occasion, it all depends how you use you're computer and how much you want to customize. Don't be afraid of terminal though, just start with basic YouTube tutorials.

The last piece of advice I feel I should give is when switching to Linux you'll have to get used to installing software in mutiple ways. Linux Mint is great because you have access to all the major ways software is direstributed on Linux. I use the apt package manager, sometimes by adding new software repos to it, AppImages, Flatpack, and .deb packages. I usually just use whatever method is recommended on a softwares website. For Appimages definitely use the AppImageLauncher manager software.

Last thing. I see a fair number of bad opinions of Cinnamon, the Desktop Environment that ships with Linux Mint, but I've never understood why. It's very familiar to a Windows user, has a simle UI, and has any feature I've needed.

That's my two cents from a relatively recent Windows refugee. I know distro wars can get heated, so remember this is just one opinion on what a good entry point is for the world of Linux.
