RE: System recovery options
Did you buy this new direct from Dell or is it 2nd hand?
You can clean install Windows 7 using Dell OEM System Locked Preinstallation. First press [Windows] and [ r ] and type in msinfo32 and press [Enter].
Let us know the system model, the BIOS version and the SMBIOS version.
