I have client who is about to fit in a new Dell drive into his Dell laptop. The old drive had Windows 8.1 on factory install, later upgraded to Windows 10 when it was still free.
Since then the HDD failed and so he had to order a new one. Of course there are no discs with the Dell to install the OS because it was on a recovery partition on the old HDD. How can i get the OS installed again and licensed with Windows 10 as it was before?
