Hi, I'm trying to install Windows 10 on my Mac book pro retina, which I purchased in September 2015. It is running OS X El Capitan 10.11.1. I have the ISO Windows file on my desktop as instructed. When following tutorials on YouTube and instructions on the internet my bootcamp doesn't open with the same options as what is suggested it should. Mine jumps straight to the part where you partition the hard drive and select the iso file you want to use. Once it has done this it then will not open windows it justs keeps opening the OS X system even though it says it has been successful. Hope this makes sense and somebody can help. Many thanks.
