You'll need to download the windows media creator utility from Microsoft (google it). This will download a clean install of Win 10. It will ask if you want to update this PC now or create installation media for another pc. Choose the latter, Inserra USB w at least 8GB and install to it. Next, go to settings-- update-- recovery-- advanced startup. Choose restart. When prompted, choose troubleshoot. Then choose change UEFI BIOS settings. This will bring you into your BIOS. Change boot device to the USB, then restart. Windows installation will begin. Choose the disc currently in the laptop by deleting all partitions and agreeing to format the drive.
That's it.
