I just put a cd drive in a computer, it plays cd's but when i try to download an os on the computer it dosen't recognize the drive. do i need to download drivers or do something in bios.--very novice just trying to figure this out

No, you simply need to tell your BIOS to boot try booting to a CD before the hard drive.
