During the upgrade process you can choose whether you want to keep all the files on your system or start fresh.
Windows may restart during the install process.
Install windows as usual but don t format your drive this time in the installer otherwise it will erase the windows 7 setup files too.
If you prefer a clean install you can select create installation media and then provide a valid windows 7 or 8 key while installing windows 10.

Next follow the normal windows 7 installation procedure to finish the installation.
