Just recently bought a toshiba satellite laptop, vista equipped. Didn't like Vista from the start, want to get XP on it. Tech guy at the store said it might not support XP but we tried anyway and recieved the followinkg error message: Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powererd on and properly connected to your computer, and that any disk related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program. None of this makes any sense to me....any help at all would be greatly appreciated.
