Hi, A week ago I lost half of my harddrive. First I installed win7 with daz. Then I upgraded to win 7. After that, I tried clean windows 10 installation. However, for some reason I lost my half of my harddrive which was full. It became RAW. Now I want to install win 7 again. I want to do these steps: 1- install win 7 with daz 2- upgrade to 10 3- Take the produduct key with a keyfinder program 4- Format pc 5- Install the windows 10 with the product key I got 6- Activate it. Do you think it will work?
