If you want to format the partition on which Windows 7 is installed, you have to reinstall the operating system completely. Think carefully about this step, because all settings, programs and data will be lost!

Step 1:
Before you start reinstalling Windows 7, you should first back up your most important files. Don’t forget documents, pictures, emails or possibly saves. Save everything on an external hard drive or a USB stick. For security reasons, rerun an anti-virus program so that your new Windows is virus-free right from the start.

Now insert the Windows 7 DVD in your PC drive and restart the computer. Now you have to change the boot order so that your PC boots from the DVD. To do this, press the “Del” or “F2” key in the BIOS during the boot process – the key depends on the BIOS used. In the “Boot Priority” menu that opens, select your drive or DVD and confirm. Make sure that you first save the changes in the BIOS and later reset them to the hard disk.

Step 3:
Now the Windows installation starts. First, the “Install Windows” window opens. Here you select your preferred language, the time and currency format as well as the keyboard layout. Unless otherwise requested, set everything to “English” and click on “Next” and then on “Install now”. After starting the setup, read the license terms, accept them by clicking the small box below the license and confirm with “Next”.


Step 4:
Now select the type of installation. Since you want to reinstall Windows 7 completely, click on “Custom (extended)”. Now select the respective partitions or hard disks and format them first by clicking on “Drive options (extended)” and then on “Format”. Once you have formatted all hard drives, select the hard drive or partition on which you want to install Windows. Then click “Next” again.


Step 5:
What follows is the actual installation and update of Windows 7. This process can take some time. If there are no problems, Windows will restart the computer twice during the installation. After the second restart, Windows will ask you for some input.

Step 6:
First, you need to provide a username and a computer name. Confirm your entries with “Next”. This is followed by entering the user password, which can optionally be set up for your Windows user account. Now define the update settings for Windows 7. For optimal protection of your system, the “recommended settings” should be used.

Step 7:
The date and time settings follow. As soon as these have been made, click “Next” again. Finally, if your computer is already connected to a network, Windows will ask you to confirm the network settings. As soon as you have completed this last step, you have successfully installed Windows.

    I had an old laptop that was unused for 3 odd years. I followed similar stepsand formatted it. The result was exceptional. The formatted laptop was pretty similar to a new one and helped in increasing the performance as well as speed. I can very well use it for my kids online classes.
