A couple of years ago I got help here installing Linux onto an old laptop. Sadly, my wife (who is the main user) hates it and is keen to go back to windows. So I'd like to have a shot at putting a clean installation of windows on it to see if it's usable - it might be that the specs are just too old, but I think it'll be able to manage to run MS office and a browser, which is all that she really needs. Planning to put Win7 on and then immediately upgrade to 10, as Win7 support is all but over now.
I have the original Win7 disk with the product key, supplied with the laptop. It doesn't have a DVD drive so I'm trying to create a bootable USB drive. Rather than mess around with the disk I've just tried to download the Win7 ISO file from Microsoft, but when I put my product key in it says 'The product key you've entered appears to be for software which was pre-installed by the device manufacturer. Please contact the device manufacturer for software recovery options.'
Do I really have to go back to Dell to ask them for a new copy of Windows for a laptop they sold me in 2009?? As far as I'm concerned, this is my copy of Windows, purchased for this exact machine, and I ought to have the right to re-install it! I can still create the USB from the disk, but I imagine that when I try to register it I'll get the same problem.
Ideas? I know I can buy dodgy keys from eBay - is that actually the simplest way forward? Will the upgrade to Win10 work with those keys?
