With one hard drive there is no raid....
It should be as follows(unless there are more then 2 ide channels...if there are still try to get the hard drive on Primary or IDE1)
HDD(Master, black on cable far end) on primary IDE
nothing(Gray, middle connector)
Primary IDE. Motherboard (Blue)
DVD1(Master on black connector)
DVD2(Slave on gray cable)
Secondary IDE. Motherboard (sometimes black on the board....blue on the cable)
Since you are in a state of not being able to boot, maybe you should reset the bios with the clear jumper(normally near the battery)
