I have a 2009 Mac with a new blank SSD. I have a Snow Leopard install disk but it doesn't work (it was a replacement installer disk and has never worked), so I don't have a working OS X install.
I do have a Windows 7 machine.
How should I go about installing Yosemite? All instructions I can find require OS X at some point in the process. I can't even download it from the store unless I'm on a mac.
