Hi & Welcome to LQ.
I only used Deepin for about 2 weeks.
Deepin is based on Debian Unstable and it ran well on my desktop but it wasn't for me.
Everything ran well and the wifi worked right out of the box.
Basically you would download Deepin and burn the .iso image to a CD/DVD. (see the second link)

OR> If you'd prefer not to use up all of your CD's and DVD's......
You could try Deepin without installing it install Virtual Box or one of the other VM on your Windows 10 machine.
-::-Before you go to install Linux Deepin (if you want to keep Windows) you will have to shrink your Windows partition to make room for your Linux installation.-::-
Since your HP is new I suspect that it is a UEFI machine. That means you will have to go into the BIOS and disable the 'secure boot' and 'quick boot' and the like before installing Linux.
