Holy crap that's a nice laptop.
Anyway, I have a dual-booted windows 10/ubuntu laptop I use as my personal laptop right now (but I've used Windows maybe once ever for like 5 minutes). If you haven't had much experience using ubuntu, I would consider dual-booting unless you're sure you want to wipe windows completely.
In any case, you'll first want to create a recovery drive of your Windows OS (which you can do within Windows, just google it).
The other main thing you should do is try to find a recent tutorial about installing ubuntu on a windows 10 machine.
Another thing to know about is the bootloader- I'd recommend at least looking into it a bit, it's basically what launches your OS when you start your machine. Usually when you turn your computer on, the bootloader starts Windows up automatically, but when you install linux, you have to trick your computer into not starting windows and instead starting up into the bootloader's menu, which can be a pain with newer boxes.
The general gameplan for dual-booting linux is:
1) burn a ubuntu installation usb (https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-windows#0)
2) Clear some disk space using the disk management tool in Windows
3) get your computer to startup in the bootloader menu instead of Windows
4) from the bootloader menu, tell it "hey quit booting into Windows by default. Instead, when you startup, boot from my Ubuntu installation USB (or CD)"
5) reboot the computer (which you can do from the bootloader menu, you don't have to power off necessarily), at which point it will boot into your installation USB or CD and then the rest is downhill from there
If you're wiping your whole system clean and starting fresh, then the gameplan is going to be similar once you get into the bootloader.
The only other thing I'd mention is that just be forewarned- linux doesn't always play nice and sometimes you have to spend an hour here or there figuring out what you think would be a simple problem. For example, on my first ubuntu laptop, the wifi didn't work so I had to link up with cable to the internet and then download a special driver. The first time I ever installed ubuntu, it took me about a day (I was also pretty careful). Last time I did it (yesterday as a matter of fact), it took me 30 minutes while watching a soccer match because I knew exactly what to do. Stuff doesn't always work 100% out of the box, so just be aware of that.
That said, I think everyone should be on ubuntu. Since I switched form Windows to ubuntu about 1.5 years ago, I haven't looked back. Ubuntu is so much better and if you get a working system, you're going to love it much more than Windows or OSX, at least I did.
Sorry if this is too much too fast, I have no idea how much you already know about the topic
