Installing Windows 7 on a 27 Inch 2012 iMac and getting Black Screen

OS X Yosemite

Version 10.10.5

iMac (27-inch, Late 2012)

Processor 2.9 GHz Intel Core i5

Memory 8 GB 1600 MHz DDR3

Graphics NVIDIA GeForce GTX 660M 512 MB

I am trying to install Windows 7 onto a partition on my iMac. I have the Windows software on my portable hard drive. I am using a USB thumb drive to install the boot software onto. Using Boot Camp Assistant, everything works fine, right up until the computer restarts to begin the Windows install. The computer does the restart chime, then goes black where it stays forever or until I restart the computer. I've tried the process as described in the page on this link -> Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support and I get the same result. I've read a half dozen options on various websites but nothing seems to work. Can anyone offer some help?

iMac, OS X Mavericks (10.9), Pages 5.0.1

You are using two USB devices. It will not work.

1. Download a W7 64-bit ISO from https://www.microsoft.com/en-us/software-download/home and put it in Documents folder. Disconnect your portable drive. Your USB Flash drive will be formatted and erased and configured with files as a USB Installer.

2. If you want to use the USB only for BC drivers, you will need an external Optical drive containing a physical Windows DVD.
