I have two PCs and would like to remove the OS,W10, on one and replace it with W7. It would then be removed from the net and not used online and I would be able to use programmes that ran happily on everything since 98se up to W7. However, I am unable to shift W10, do a W7 installation over the top or anything else. I have even tried DBAN using Rufus on a USB stick to no avail. 

I have tried so many ideas gained from Google that I can't remember the various happenings other than during attempted W7 installs I am informed that a file has not been signed off. I suspect that before advice of cyberpunk fashion can be given I will need to repeat here the various attempts, optimistically, if only for my sanity, this won't be required but if so I shall have to start again and make notes.

Any help appreciated.

I purchased a W7 disc when it came out to escape its predecessor so that isn't a problem, but thanks.

Is there something missing on the previous post?

Unfortunately, since you can't boot from the DVD drive and you can't see it in Windows, I wouldn't be able to help you get W7 on there.

Wiping the hard drive would not help.

If by some chance you ever get W7 installed, at least you have the drivers you need to get it running right.

W7, at least in part, is installed. Clicked on all programmes and got this picture. Programmes can be opened.

It was installed following your post re Legacy and Secure Boot.
