Try running Dell Factory Recovery again: Dell Restoring Your Computer´s Software to the Factory Settings

If it fails again, try booting the Recovery Disks which you either have made or order from Dell.

If you have access to a Win7 retail installer, you can clean reinstall with the Product Key on the COA sticker on machine following these steps: Reinstalling Windows 7
