set your cd/dvd drive as the first boot device, then set the sata drive as the second boot drive...take the master ide off the list. Then install windows on your sata drive, then format the master ide drive. You could format the master ide before but just incase you need to boot into windows before you install on the sata, you still have it (just make sure to set if back to the first boot device if you do).
Also you will lose your data on the master ide drive when you format it, so put everything you want to keep on the slave ide or burn some dvds if you don't have enough room on the slave ide.
