One of the easiest ways to clean the hard disk on the operating system -connect it as a secondary hard drive.Locate a second computer and connect it to your hard drive.Start the operating system installed on the second PC or laptop.Open "My Computer", right click on your hard drive and select "Format".It is preferred to perform a full format of the disk partitions.To do this, before you click "start" uncheck the item "Fast (clearing t
he table of contents)."This operation can be carried out not only from the system partition.

If you are unable to connect your hard drive to another stationary PC or laptop, but you have a second hard drive, install it in the new OS.Run the newly installed operating system and then repeat the steps in the previous step.

If the first two options are not suitable for you, you act differently.Insert the disc with any operating system family of Windows.Start the installation process.Wait for the moment when you will be given the choice of the hard disk on which you want to install the OS.In the case of Windows XP, select the partition on which the operating system is already installed, which should be removed.In the next window, select "Format (full)".After formatting abort the installation of the OS.
