Try it! You can always go back.

If you can find another HDD or SSD then you can keep your windows drive full of games intact.

I dual booted for years (for gaming) and as of now haven’t used a non-linux PC for more than a decade at home or professionally.

I recommend starting with either Fedora or Ubuntu as they’re among the most popular and have a large community for support.

Set yourself a goal on Linux, even if it’s just “check my email” or whatever. Rinse, repeat.
