The problem is that Windows does not have the drivers needed how to manage the sata chipsets. You will need to go to the manufacture of the computer or the manufacture of the motherboard. Download the sata/chipset drivers. put them on a floppy. During the booting of the CD, in the bottom, it will get to a section of hitting a F# key to load third party drivers. Hit the requested key and then it will go thru the steps of loading the drivers, then it will continue and you will see the harddrives. I went thru this exact same scenerio with a client.
