How to connect Macbook pro's Retina screen with my Mac mini? I want to use my Macbook Pro as a screen of my Mac mini(with both OS X and Bootcamp Windows).
I've following cables:
 1. Thunderbolt to Ethernet
 2. Thunderbolt to VGA

Any possible solution?
As far as I'm aware, it's not possible to run a Macbook Pro in Target Display Mode, only iMacs.

BTW, VGA or Ethernet to Thunderbolt is a physical impossibility.
Your cables must be  Thunderbolt to VGA / Ethernet.
