Hi there, you need to enter the BIOS and select the optical drive (your cd/dvd drive) to boot before the hard drive. Look for a menu or option about "Boot Order Priority". Save and exit.
Then reboot your computer with your OS disc in the drive.
p.s. Your hard drive connects via SATA, the new way of connecting. It's much better in that a) the cables are much smaller, allowing better airflow through your case, and b) SATA allows for much faster data communication, meaning it's going to be quicker
You don't need Master/Slave with SATA, you just need to set it up right within the BIOS.
Because you have two optical drives, maybe you should disconnect one for now (the one you want as slave), leaving only the master. Then once everything is sweet, plug it back in again.
