You must backup all your data before beginning with the hard drive wipeout procedure. Grab all your original disks including installation and manual also if you really feel the need. Scribble down the product key of your operating system (OS) and other applications such as MS-Office before wiping out anything.

If you don't have the product key printed anywhere on the disk or manual, check your email (if you purchased your OS online, then you might have received the product key in your email). If you are unable to retrieve product key from you email also, then download and run a product key finder from the internet. The automatic program will help bring out the OS product key just in minutes. There are many free and paid tools available on the internet for various Windows OS versions. Choose one that best fits into your requirements and is designed for your OS. Download from a trusted website to avoid carrying virus, malware infections to your computer.

When done, insert the Windows installation CD or DVD etc. into the drive and restart your computer. If you have the installationsetup image (of OS) burnt to a USB flash drive, then insert it and choose to boot from that.

When prompted, hit any key on the keyboard to bring up the Windows setup screen. Hit the Enter key and subsequently the F8 key on the keyboard on the setup screen. Click to choose the existing Windows installation and then hit the D key on keyboard. Hit the Enter key and then the L key to wipe out the hard drive. It might take some time, so be patient.

When done, hit the C key (on keyboard) to create a fresh partition on the hard drive. Subsequently, press the Enter key to choose the newly created partition. Choose FAT32 or NTFS file system as per your OS' requirements. Older Windows versions support FAT32 while newer ones support only NTFS. Check your manual for precise information on what file system your Windows supports. Follow the instructions and complete reformatting.

When finished, re-install Windows OS. Follow instructions carefully as the installation is a very sensitive part. Fill in all the information accurately like product key, accept the license and terms and conditions and complete the procedure. When prompted, reboot your computer. Install and configure all the applications like drivers, software, programs etc. individually. It must be noted that your computer may reboot several times during this procedure. It is quite normal and nothing to be worried about.

Additional Tips:

You must have admin privileges to perform such changes. Be sure to backup your data before performing such steps. Failing to do so will result into data loss.
