Alright, what you can try is using the windows 10 media creation tool: http://www.microsoft.com/en-gb/software-download/windows10
And instead of pressing Upgrade this PC, you create an install for a media device such as a usb (you don't actually need the usb).
You will want to save it as an ISO, this comes further into the process, you can't miss it.
Once its downloaded the ISO, you can just extract it, and run the setup that is in the new folder it created
