How to Reinstall Windows Operating Systems

1. Insert the Windows installation disc into the disc drive, then restart the computer.
2. Boot from the disc. Many computers are set to boot from the inserted disc automatically. You may have to press a hotkey to boot from the disc. Common hotkeys are 'Esc,' 'F8,' 'F10' and 'F12.'
3. Click 'Install Now.'
4. Click the check box, then click 'Next.'
5. Click 'Custom,' then click the desired partition on the hard drive. If no partitions exist, one is created automatically. Click 'Next.' Windows begins the installation process and restarts the computer automatically.
6. Follow the onscreen prompts to customize the Windows installation, including the initial user account name and the time zone.
