Windows- bootcamp won't start after installing OSX Yosemite - Ameriguayo

Like so many others, I installed OSX Yosemite this morning and now Boot Camp no longer works.

After I updated to Yosemite I restarted my computer, held down alt, and was presented nothing but a Macintosh HD. I followed “Loner T’s” instructions. Here's my info...
