There are full instructions on the Installing Windows 10 using the media creation tool page.

Specifically, you must first upgrade the PC instead of performing a clean install, to make sure your old Windows 7 or 8.1 license is recognized as a valid license for the free Windows 10 upgrade. See the Download Windows 10 page for details, but be very aware of the fact that your “genuine” license is dependent on running the upgrade sequence correctly. If you continue to have the same problem, Microsoft’s best advice is to use the Windows 10 media creation tool to create a USB drive (or DVD). If you’re working with any Enterprise version of Windows 7 or 8.1, the upgrade isn’t free-it’s dependent on your Software Assurance license terms. If you started with Win7 Pro or Ultimate, or Win8.1 Pro or Pro for Students, you should install Windows 10 Pro. If you started with Windows 7 Starter, Home Basic, or Home Premium, or Windows 8.1 (standard, usually called Home), you should install Windows 10 Home. Second, make sure you have the right upgrade: 32-bit for 32-bit machines, 64-bit for most. If possible, consider turning off Wi-Fi and plugging into a router with a LAN cable (that worked for me). Yank that external hard drive, disconnect peripherals that aren’t absolutely necessary, including extra monitors, smart card readers, weird keyboards, whatever. Installer hangs for hours or reboots continuouslyįirst, make sure you’ve disconnected any nonessential hardware: Unplug all hard drives other than the C: drive.
