I wouldn't recommend dual booting anything with Windows, especially if you're not familiar with installing multiple operating systems. Windows will pretty frequently fuck up your boot settings when it updates because it doesn't respect not being the only OS on your system and will cause way more problems than it solves.

My recommendation if you really want to stay on Linux is to run Linux as your only OS and then run Windows from a VM for the apps you absolutely need to use. VirtualBox or GNOME Boxes are good options if you want a regular Windows VM with little to no integration with the host Linux instance. There are also software that will create an experience like Parallels on Mac with Windows apps that appear as regular windows in your Linux desktop (I've heard about WinBoat but don't personally use it so can't say if I recommend it or not). For most games, Proton should have you covered.

If you want distro recommendations, I'd say Fedora or Linux Mint are good options for general users getting into Linux. If you do a lot of gaming, I've heard good things about Bazzite.
