Boot Camp after Yosemite, Can't boot

Question

Like others, I can't boot to Windows 7 after Yosemite install. I've followed a couple of Loner T's posts, but I haven't gotten it working yet.
What's a good starting point to

Answer 1

I believe I've done it correctly, but it still doesn't work. I can see the partition in Disk Utility but not Finder.
I would be fine reinstalling Windows. But I'm not sure how to get Windows to install on the partition if I erase the current disk5. Yosemite seems to be a bit different then getting it set up on Mavericks.
