If your BIOS doesn't detect the optical drive, then Windows can't either. This indicates a possible hardware failure with either the optical drive (most likely) or the physical interface (SATA or IDE) or cable connecting to the motherboard.
If your optical drive is removable, try removing and reseating it (put it back in).
Otherwise, it might be time for a new optical drive. What make/model of HP are you using?
