Do you mean reinstall? Your Windows install disk that you originally used to set up your computer should work. If you bought the computer with Windows preinstalled, it should have come with a Windows CD, or at least a system restore CD, or at very minimum with a special file you should have used to make your own restore CD. If you lost that CD or never made one, then you'll probably need to go to a computer store and buy a new one though you may be able to order one from your computer manufacturer for a small fee.

Reformatting a hard disc will wipe the contents from the hard disc. You will need to backup the contents of the hard disc onto an external disc before reformatting and then copy the contents back to return it to the newly reformatted disc.
