As I understand it, for you to get the free Windows 10 upgrade, you have to first do the upgrade of your current O/S (Win7 or Win8/8.1). After you have successfully done that and registered with Microsoft (so they can capture a digital signature of your system to support future installs), you can then download the ISO for Windows 10 and burn it to DVD, then do a clean upgrade. Since you are registered with Microsoft, you won't have to enter a license code - you're login does that.

I did the upgrade (which worked fine), and I subsequently did a clean install to a blank hard drive, which didn't cause any hiccups with Microsoft. The upgrade was a 7200 RPM hard drive; the clean install was on an SSD, and Microsoft didn't seem to care, so obviously the disk isn't part of the digital signature. I think it actually reads something off your motherboard.
