I recommend dual booting Windows and Linux until you’re comfortable switching entirely. Sometimes you need to go back for just one task.
Always back up your files before installing a new OS. Data loss is always possible during installation, and more likely if you don’t know what you’re doing.
The Grub boot manager (included and installed by default with Linux Mint and some other distros) makes it easy to pick which OS to boot each time when turning the computer on.
Check out Lutris for non-Steam Windows games. It uses Wine, but is a lot more user friendly to set up and use.
I second the Framework laptops. I’ve bought 4 Framework 13s so far, and no issues with any of them.
