Formatting a computer is not easy but it is necessary. There are few people who haven't suffered from a slow system caused by spyware, viruses or certain configuration settings. To begin the process, you should be aware that formatting the computer means wiping all the files you have on your hard drive, including all your photos, software programs and documents, in order to start afresh with a problem-free computer. If you're ready to undertake a deep clean to format and install Windows 7, you will first need to make a copy of Windows 7.

You'll need:

  • Make a backup of anything you want keep (programs, photographs, documents etc.). This step is crucial to prevent data loss during the formatting process.
  • Remember that programs used regularly, such as the Microsoft Office pack, for example, cannot usually be copied directly. Instead, it must be reinstalled from the original CD. Having your installation media ready will save time and prevent disruptions.

Steps to follow:

1

The first step to format your Windows 7 system is to turn on the computer and as soon as you see text on the screen, press the 'DEL' key to enter the BIOS. Sometimes, the BIOS can also be accessed by pressing F1, F2 or F10, and often text appears on-screen to tell you what key to press to enter the BIOS. It should be noted that accessing the BIOS might vary slightly depending on the manufacturer.

2

In the BIOS menu, select 'Boot Order' or another similar option, such as 'Advanced BIOS Features', which can be found in 'Advanced Options'. Note that the BIOS setup on each computer varies. Refer to your machine's user manual if in doubt. It's crucial to set the boot order correctly to ensure the installation proceeds smoothly.

Select 'First Boot Device' tab and choose the CD/DVD option so that your computer will boot from the Windows 7 CD. Make sure the following options are set: 'Second Boot Device: Floppy' and 'Third Boot Device: Hard disk'. Keeping these settings ensures your system checks for the installation media first.

Press 'F10' to retain the new settings you've just entered. Press 'Esc' to exit the menu. Remember to press 'Y' (yes) when the computer asks if you really want to save the changes. This step is critical as it locks in your changes, preventing any boot errors during installation.

5

After restarting the computer, insert the Windows 7 Installation CD and wait for the computer to recognize it. This will begin the process of installing windows 7 again after being formatted. Ensure the CD is clean and without scratches to avoid read errors.
