How to Dual Boot Windows and Mac OS

My friend is trying to Dual boot his PC to be able to choose Mac (yosemite) or windows 7 on boots, I was wondering if anyone would help me with that information. Also he wants to keep his current info and make just a different partition on the same hard drive as the Windows 7 OS. My thoughts are that you cant have two different formats on one hard drive, I believe mac is a completely different file format, but he wanted to know from people that actually knew, I told him that he would probably have to do it on a completely different hard drive if it could be dual booted at all.

Is he doing it via Boot Camp, or on a PC?

on a PC that already has windows 7 installed

Is he doing it with a Hackintosh distro, like Yosemite Zone?

Be aware that running any Apple OS on non Apple hardware is a violation of Apple's EULA. For me that is the end of discussion. Yosemite is a pirated version of OS X and cannot be discussed on this forum.

Exactly why I asked that question.
