STEP BY STEP HOW TO NSTALL WINDOWS 10 FROM SCRATCH

If you haven’t installed Windows 10 on your PC before, you’ll have to perform an upgrade first before you can clean install. If this doesn’t make any sense, that’s because Microsoft never makes licensing easy, even when there’s a free version. Once you’ve performed the upgrade and activated your Windows 10 upgrade on a PC, Microsoft will associate your unique hardware ID with an activated Windows 10 license, and you can reinstall as you see fit. But not until you’ve upgraded Windows 7 or 8 to Windows 10 and then activated.
Just keep in mind that Windows 10 is only provided for free as an upgrade. You can’t clean install it, there are no keys at this point. Unless you use our clean install workaround.
