I have a Dell Inspiron 3647, that came from the factory with Windows 7 Home Premium SP1 64 bit. I upgraded for the free Windows 10, and after several months of using it I continued to have compatibility problems with my software programs I was using. I now want to downgrade and go back to my Windows 7 operating system. Because of the time period, I can not go back to Window 7. It is no longer on my computer. I have the installation disc and drivers disc. Can someone tell me where there is a good tutorial that I can use to do a clean installation and put back my Windows 7? I want to format my hard drive and start over.
Thanks,
