I have a 2012 13 MacBook Pro. I installed a SSD in the main bay and a 1TB HDD in the optical bay. OSX is installed on the SSD, and I created a 60gb partition to install windows on the secondary 1TB HDD. My first attempt failed as Windows would not install to a secondary hard drive. I did some googling, found this guide and used it. Windows seemed to install fine with the primary SSD unplugged. I plugged the SSD back in and rebooted into OSX and that is working fine also. But now, when I try to boot into Windows, I just get a black screen with a blinking cursor. Any idea why that is or how I can fix it? Is it possibly a driver issue? I was not able to install the apple support drivers near the end of the guide I linked to above since I can not get back into Windows now. Any help is appreciated. Thanks.
