  • Scroll down the page and select the option titled Recovery.
  • Click the link ‘Advanced recovery methods’.

Windows 7 Clean Install Using an Upgrade Disc

Using an upgrade disc requires an extra step, before you can get Windows 7 activated. After you have removed Windows 7 and reinstalled, you should have Windows ready to go. However, you will not be able to activate Windows 7 with an upgrade key, because using a Windows 7 upgrade key and disc requires you to upgrade from a previous version of Windows. Because you have clean installed using an upgrade disc, you need to trick Windows into believing that you have upgraded from a past version of Windows.The following steps will allow you to activate Windows 7.

  • After removal of old Windows and clean install, make sure that your computer is powered on and you are logged into Windows.
  • Insert your Windows 7 Upgrade DVD into your computer’s CD/DVD drive.
  • Once the install disc loads, choose the option to Install now.
  • The next screen will present you with two options. Choose the upgrade option.
  • Follow the on-screen wizard to initiate the upgrade process.

Once Windows finished upgrading, your key will be functional and you can activate Windows 7. Because you have just upgraded Windows 7 on top of Windows 7, Windows detects this as an upgrade. The Windows 7 clean install using an upgrade disc should be complete.

Installing Windows 7 Drivers

After installation is complete, you may need to install drivers so that your display, sound, video, etc… works with Windows 7. Finding drivers is not a general process, as each PC manufacturer is a bit different. If you bought your computer from a manufacturer such as Dell, Gateway, or HP, you should have gotten a drivers CD/DVD with your PC. Simply insert this disc into your computer’s CD/DVD drive and follow the on-screen instructions for installing drivers.

If for any reason you don’t have a drivers disc, you can always download the drivers from manufacturer websites.

That’s all there is to it. Now all you have to do is copy your files from backup back to your new clean Windows 7 install.
