I installed a new SSD in my PC laptop which came with an OEM version of Windows 8. After trying unsuccesfully to get the OEM version of Windows onto the SSD drive I gave up and purchased and downloaded a NEW copy of Windows 8. After that I created an ISO image on my desktop machine and followed the instructions here to create a bootable USB flash drive.
However, after going through the boot install process with the USB flash drive on my laptop I get the following message
'The product key entered does not match any of the Windows images available for installation. Enter a different product key.'
But I wasn't asked to enter any key!
Is this because the ISO image was created on a different machine? I really don't get why this should be so difficult.
