Most Linux distros come packaged so that they can be booted as a "Live CD". What that means is that, if you burn the ISO you have to a CD or DVD, you will be able to boot from it and run that OS from the CD without actually installing it on your machine. That way you can test things like whether or not you like the OS and whether it supports things like your mouse/trackpad, sound card, wifi/network card, etc... before actually installing it.
I recommend that you try Xubuntu that way first, before trying to setup a dual boot system.
Personally, I haven't used dual booting in many years. I have multiple versions of Windows and Linux on my machine running in what are called VMs - Virtual Machines. It may require a little effort on your part to learn how to create and use VMs but it would pay off in the long run since you state that you "have a huge interest in trying things new." VMs allow you to run multiple OSes from your machine.
The software to create and run VMs is often free, if you're interested, try this website: https://www.virtualbox.org/
