Don't get it. How is fresh install without loader possible? Can u use the recovered (uncovered) product key?
Could you not be able to express more clearly what you do not understand and what recovery keys you are talking about? And the strange thing is that you comment a post that was made on Jul 28, 2015, that is, about 5 years ago. Why? If you have a problem, write about your problem, and don't make these weird comments about such old things.
