Thank you for your reply HotCakeX
I've decided to renew the hard drive.
I left it on, went shopping to come back home to find it with a green screen saying a problem with the "Insiders Build and it will restart".
I tried, but it would not restart.
I don't remember having an saving a ISO Image when I made the changes from Win7 to the Insiders Win10.
So sorry I took so long to get back to you.
