Windows 10: Bluetooth is missing on device manager section

I am using a Sony Vaio Laptop Model Number SVE15127CNB which came with windows 8 preinstalled, later I upgraded to windows 8.1 and 10 respectively, as it became so slow using windows 10 as my laptop having 4gb of RAM and HDD, I decided to move to using Linux, after spending couple of months using Linux I reinstalled windows 10 again, and now everything is working fine except the bluetooth, the bluetooth is totally missing on my system, it didn't even show up in the device manager section, I tried troubleshooting and it said my device doesn't have bluetooth, I used bluetooth a lot when I was us
