Windows not able to recognize Bluetooth Device after Dual Booting Linux.

Question

I had installed Fedora because while using Windows my Wifi Card kept getting disconnected and I thought this was Drivers' issue. This issue still persisted even after dual booting, but with this the Bluetooth issue rose up. I had connected my Bluetooth earbuds with Linux, but when the wifi problem had still persisted, I got so furious that I deleted Linux from my system and reverted back to Windows and this time Windows was unable to detect my previously connected bluetooth devices. I ran troubleshooter for this, I tried different Bluetooth drivers in order to make it work but it all went down the drain. Hell I even did a clean install of Windows and yet this issue still persists.

I figured out the Wifi problem was actually because of overheating in the region where Wifi card is located so it was disconnecting every time and I cleaned it so it worked fine. I also did some research regarding the bluetooth problem and it seems that connecting my Bluetooth in Linux changed its MAC Address or something and Windows is not recognizing it, I'm not sure if this is even the case here. Please help me with this bluetooth problem.

Hello

Thank you for posting in Microsoft Community forum.

You might need to manually edit the registry to fix the Bluetooth pairing issue. This involves copying the Bluetooth pairing keys from Linux to Windows.

Here's a simplified version of the process:

• Pair the device in Linux and note the MAC address.
• Install chntpw in Linux to access Windows registry keys: sudo apt-get install chntpw
• Access Windows System Drive in Linux and navigate to the Bluetooth registry keys: cd /[MountedDrive]/Windows/System32/config sudo chntpw -e SYSTEM cd \ControlSet001\Services\BTHPORT\Parameters\Keys ****
• Copy the pairing key from Windows and paste it into the corresponding file in Linux: sudo nano /var/lib/bluetooth/[Unique ID]/[MAC Address]/info ****
• Restart Bluetooth service in Linux: sudo service bluetooth restart

Additional Tips:

• BIOS Update: Sometimes, updating the BIOS can resolve hardware compatibility issues.
• Check for Interference: Ensure there are no other devices causing interference with your Bluetooth signal.
