Richard, it may not be a matter of recovery media, we can test that, but it sounds like it could be a harddrive failure causing this.
If you need recovery Media, you are fine with buying a new version of Windows like this http://www.amazon.com/Microsoft-Windows-Home-System-Builder/dp/B00ZSI7Y3U/ref=sr_1_1?ie=UTF8&qid=1458692925&sr=8-1&keywords=windows+10
That would be considered recovery Media. But I'm not sure that is your problem.
