Triple boot Windows 8.1, Linux Mint 17.1 and CentOS 7

I know that it might sound like a dumb question but I am unsure what the right way to do this is. I want to triple boot Windows 8.1, Linux Mint 17.1 Cinnamon and CentOS 7. I have installed Windows 8.1 on my laptop and I would like to install two more operating systems - Linux Mint 17.1 Cinnamon and CentOs 7. The problem is that I don't know how to properly partition the hard drive. Are there any rules that I have to follow? Is CentOS going to recognize the other operating systems installed - namely Linux Mint and Windows? In other words which one should I install first?
