long story short I installed windows 10 on a 2013 macbook pro using bootcamp
After installation it was booting to windows but I wanted it to boot into os x instead. When I went into boot camp, and tried to boot into os X, it would always return the error:
Could Not Locate the OS X Boot Volume

Update boot camp through Apple Software Update. That's it.
