No, that disc is drivers and, well, utilities. It's not the OS restore disc. That is a separate disc, usually sort of a maroon color while the driver disc is a bright blue. So don't go wiping the drive until you find that second disc. Then it is basically putting the OS disc in the drive, booting from it, and following instructions. Later you use the driver disc to install the drivers for the system, or alternately you can go to the Dell website, put in the system's service tag, and grab the latest versions of the drivers.
