The switch or dual boot is up to you. I can lay out some general steps in case you want to have an overview. Please do not be scared off by it. Depending on the distro, most things work out of the box or with very little effort.

1. familiarize
   • look up some distros, I personally like to go Arch-based, but feel free to use whatever seems good and popular enough (please no Ubuntu)
   • try virtual machine and then live ISO
2. verify compatibility
   • this one is a bit more work, basically try all functionality in the live ISO, or at least things like display, mouse, keyboard, touchpad, Wi-Fi, storage
3. install
   • you probably won't need to look into this super deep, default installers handle this pretty well
   • formatting and partitioning (look into ArchWiki guide, you probably don't need swap partition)
   • if you are going to be reinstalling look into using efibootmgr to possibly clear up old and fix existing boot entries (i had to enable boot flag after setting up dualboot, because macOS installer overwrote the previous settings, thanks Apple :-) )
4. configure missing/not working OS stuff
   • look for missing drivers and system management software for either your specific hardware or some more general ones
   • best sources are wikis like ArchWiki (even if you don't use Arch), forums and some software search sites like AlternativeTo
   • in some cases the software does not meet the requirements for a wiki page to be up (Xlibre being notable example - feel free to look up the whole story)
   • you may have to put some time into getting GPU fully working, since nvidia has several driver options depending on the GPU
   • I personally had to fix USB autosuspend config, only look into it if devices plugged in after boot are not being detected
5. use
   • installs and updates are done using package manager (windows has winget, btw)
   • for windows games use Wine or rather some of its forks
   • most people here already shared their recommendations for this part
