Gateway, and no. The two machines use different chipsets IIRC. I believe the 7500 series started using the ATI/AMD chipset, whereas the m6811 uses the VIA chipset. The restore CD/DVD is an installation image, meaning it is preconfigured with the appropriate drivers. It's not actually installing Windows, but just copying an image to the HDD.An attempt to do that would likely result in a blue screen while booting.
