CD/DVD ROM not showing in Device Manager

Hi,

I’m having problems installing a DVD-RW.

I uninstalled it from device manager, rebooted my computer then as i went back into device manager to reinstall the driver the option for CD/DVD isnt there!?

I have tried to install by going to add new hardware but again the option for CD / DVD is not in the list of devices?

Any help would be appreciated.

Thanks.
