Hello, i downloaded windows 10 today on my HDD, still works on my HDD. but i cloned it to my SSD and want that to be my boot drive, but when i boot from it, it wants me to reinstall windows, well just add a product key really, but i dont have one. I have entered my windows 8 key from my old laptop, but its still in use? what can i do because when i really want to use my SSD as a boot drive for windows 10?
