Step 1: Insert a Windows installation disk into your computer. Start/restart it and set computer to boot from the disk. Google, "Boot Computer from USB or CD", replacing, "Computer" with your make and model of PC, - to learn how to boot a computer from USB drive or boot your computer from CD/DVD if you need to.
Step 2: Wait while booting until the Install Windows screen appears. Then select your language and then click on the Next button.
