I keep getting the error when trying to install Windows 10 as a clean install or via an upgrade route from W7. I have tried using a DVD media and I have tried the upgrade route via an installed W7 Ultimate edition. I can't seem to find what this error points to. It seems to be very basic and happens after the set up has gone through downloading and is booting for the first time after all the files have been downloaded. I have tried the upgrade route twice now. I have gone to the Microsoft website to see what this error pertains to but get no where. When using the DVD media I get the error when I load the DVD in an external USB drive. So I don't even get to the point where the language options appear. Can any one in the forum shed any light on the matter? The upgrade was done via clicking on the windows logo in the tray at the bottom of the desktop.
