"Hi I'm Robert and today we'll show you how to erase everything from your PC. The best way to erase everything in your system is to reformat your drive and reinstall the operating system. In order to do that you would need your, either a recovery disk or your original operating system. I have Windows XP on my system right now so I'm going to use the Windows XP software to reformat my drive and reinstall the operating system. Once the system boots up from the cd rom drive, you get to a screen well you'll have a selection if you want to install or repair the operating system. Pick the selection that allows you to reinstall a fresh copy of the operating system. The next selection would be a licensing agreement page, what we need to do is invoke f8, to agree. Alright after you acknowledge the licensing agreement you are going to get to another screen which is, it asks you whether you want to repair the selected Windows XP installation or continue installing a fresh copy . And what you want to do is continue installing a fresh copy of XP. So at this point you hit escape. When you hit escape it will start formatting the drive and once formatting is completed it will reinstall and copy all the operating system software into your C drive. When it's done the computer will reboot. Follow the prompt, take all the defaults and you are good to go."
