I am using Dell Inspiron 3541 laptop. Bluetooth option is not there

At first when i was using Windows 8.1 bluetooth option is present and I connected it too. Recently i have searched for bluetooth and option is not showing. I tried to install all the drivers but of no use. Bluetooth option is not available. Now after that i installed windows 10 but even then bluetooth option is not there. What to do? Any one please help.
