Dual drive bootcamp windows problem

I've a Macbook pro (mid 2012) with bootcamp 5.1.2 installed on a 0S X Mavericks (10.9.5).

After trying for a couple of months to find a solution to this "booting" problem i was able to install the windows 7 on my other drive (SSD), following some advise to unplug the main drive (OS X) to be able to install windows in the other drive. I turned the computer and verify that the installation was complete and windows was running normally. In the moment that i plugged the main drive, i chose to enter using the windows drive and the result was a black screen.

How do i pass trough this black screen?
