Bluescreen on MacBook Pro 13"

[mi_pa]

Hi I hava a MacBook Pro 13" Retina, Mid 2014 and I wanted to use WinToUSB with this.
I created both, a clone version of my Windows system and a fresh Win7 Pro system but both resulted in a bluescreen.

The Windows is starting but at one point there appears to be a problem.

I do not know what all the numbers and codes mean but maybe one of you can help me.

Thanks!
