More likely you will not be able to use the Dell Windows restore, it is an OEM install that verifys that the motherboard has a Dell bios. Many computer mfg. use this kind of install. Gateway, Sony, Dell and HP/Compaq. The only way to reuse the installation cd is to purchase another Dell OEM motherboard. I had the same problem with gateway and I found a great number of sites that carry gateway replacement motherboards. Or I haven't tried it yet: But someone told me you can change the OEM info in the preinstallation to not look for a certain bios.
