If you have a USB stick you’re not using you can install Mint on it and boot directly from the USB drive without modifying your actual OS, and see how you like it! The same is true of many other linux distributions if you’d like to explore, but Mint was my own first foray into linux and I think it’s a comfy distro to start off with. I think you’ll be shocked by how snappy it can be on a lower spec machine like that, even running from a USB stick.
