It’s also a good idea to download drivers for your computer’s various components before you begin the installation process.
However, be aware that new computers, particularly tablets, may contain components that weren’t manufactured when older Windows versions like Windows 7 and Windows Vista were being sold.
Ethernet, Wi-Fi, and graphics drivers in particular can make the setup process much easier.
Store these drivers on a USB thumb drive for easy access once Windows is finished installing. For Windows 8.1, Microsoft provides a download service that allows you to send the installation files to a new DVD, or even use a flash drive.
Click “I accept the license terms,” then “Next” on the license screen.
The next screen has two options, “Upgrade” and “Custom.” Click on “Custom” — the Windows 8.1 installation system cannot upgrade from a newer version of Windows to an older one.
