Dual Boot - Windows and MacOsX

Hey guys, I'm new to this subreddit and have been coding python 3 for the last 4 months in my Windows laptop, I want to switch to MacOS, just in case if I could find my interest in coding apps and stuff for iOS. I don't have any idea about how to dual boot 2 OS on one hardware, saw some videos on YouTube, but those guys had iOS already installed and then they installed Windows. Can anyone drop a link to an article or a video by which I can dual boot iOS (Windows already installed) without losing my data in C , D and E drive. Looking forward to use Yosemite, since I only want to use it for xCode.

My specs - 6th Gen i3 6GB Ram 1TB SSD and 2TB HDD
