I personally wouldn't want to use Dell install disks. I would download a Windows 7 iso (official Microsoft ones available from digitalriver if you can find the right link which is not hard with a Google search), use the ei.cfg removal utility to make it so that I could install any version of Windows 7 that I had a license for (just because you might as well while you're at it) and then install a clean version of Windows 7 rather than butchering the install using Dell supplied stuff. Yes, you need to download the appropriate updated drivers first, but I would not want to use a Dell restore CD. Just my preference.
