If you are trying to install Windows on the SATA drive you will probably need to load the drivers for the controller during the installation. You should have a floppy disk with the SATA controller drivers on it. Put this disk in and do everything as usual. As soon as the CDROM boots and starts the setup watch at the bottom and it will say press F6 to load additional drivers. When it says that press F6 and then S I believe and it should find the drivers. From there you should be able to continue on with the installation like normal.
