I'm trying to follow these instructions to get my computer to dual-boot Windows and Ubuntu. I followed these instructions , but when I tried to go through with it, I got an warning saying my home was too small and that it should be size '0TB0'. What gives?

Here's an image of what I got, for reference:

enter image description here

I'm using the latest version, which I think is 16.04.1. How do I boot in UEFI boot mode? I've been just doing pressing Enter on startup and then pressing F12 (which is something like boot up from temporary device), and selecting the USB from there.

You might want to look into this ubuntu post. Has plenty of details on UEFI and dualbooting. It has instructions for both ways, but advises you to install GRUB (and Ubuntu) before installing windows. Because of the way windows "works" ;-).

Hope this helps a bit!

Based on all the information that I can gather from the image and your comments, there is a problem with your /home and root / allocation. You can remedy this by deleting both and making one big partition between the two. Don't split root and home. Specify the one big partition as root /. You'll automatically have a /home folder with the install. Just as with your Windows install... it creates a /users/yourname home directory.

As far as installing, make sure that you boot into the UEFI mode. The windows installer will recognize this and give you support for the way your previous OS was already installed. If you try to install it in a different mode you might not have the multiple choice when booting your computer. You might have to spend time fixing it. Running Ubuntu install under UEFI and it'll be installed properly initially.

This answer is assuming that your Windows is already install in UEFI. If Windows isn't install UEFI, then Ubuntu shouldn't be.
