 This is a guide written on how to share the same Bluetooth device(s) across Windows and Linux without having to uniquely pair each.
 <!--more-->
-## Steps
+
+## Method 1: Extract Keys from Linux (Recommended)
+
+This method uses `hivexsh` to read the Windows registry directly from Linux without needing to boot into Windows.
+
+### Prerequisites
+
+Install hivex:
+
+```bash
+# Arch Linux
+sudo pacman -S hivex
+
+# Debian/Ubuntu
+sudo apt install libhivex-bin
+
+# Fedora
+sudo dnf install hivex
+```
+
+### Steps
+
+1. Pair your Bluetooth device(s) with Linux **first**
+2. Reboot into Windows, then re-pair the devices with Windows
+3. Reboot back to Linux
+4. Mount your Windows partition (if not already mounted):
+
+   ```bash
+   sudo mount /dev/sdXN /mnt/windows
+   ```
+
+5. Find your Bluetooth adapter MAC address and paired devices:
+
+   ```bash
+   ls /var/lib/bluetooth/
+   # Example output: 24:EB:16:23:5B:94
+
+   ls /var/lib/bluetooth/24:EB:16:23:5B:94/
+   # Example output: EC:66:D1:B1:9A:33 (your device)
+   ```
+
+6. Use `hivexsh` to extract the pairing key from the Windows registry:
+
+   ```bash
+   hivexsh /mnt/windows/Windows/System32/config/SYSTEM
+   ```
+
+7. Navigate to the Bluetooth keys (MAC addresses are lowercase, no colons):
+
+   ```text
+   cd ControlSet001\Services\BTHPORT\Parameters\Keys
+   ls
+   cd 24eb16235b94
+   lsval
+   ```
+
+   Example output:
+   ```text
+   "ec66d1b19a33"=hex(3):1d,68,ef,88,a8,fa,60,2e,a3,1c,69,2e,61,a4,36,4f
+   ```
+
+8. Convert the key to Linux format (remove commas, uppercase):
+
+   ```text
+   1d,68,ef,88,a8,fa,60,2e,a3,1c,69,2e,61,a4,36,4f
+   → 1D68EF88A8FA602EA31C692E61A4364F
+   ```
+
+9. Update the Linux Bluetooth info file:
+
+   ```bash
+   sudo nano /var/lib/bluetooth/24:EB:16:23:5B:94/EC:66:D1:B1:9A:33/info
+   ```
+
+   Replace the `Key=` value under `[LinkKey]` with the converted key.
+
+10. Restart the Bluetooth service:
+
+    ```bash
+    sudo systemctl restart bluetooth
+    ```
+

+
+## Method 2: Export Keys from Windows
+
+This method requires exporting the registry keys while booted into Windows.
+
+### Steps
 
 1. Pair your Bluetooth device(s) with Linux **first**
 2. Reboot into Windows, then re-pair the devices with Windows

 12. Paste the key from the previous step into the `Key=` portion of the **Linux** Bluetooth `info` file. Make sure to **remove all spaces, hyphens, and change all characters to upper-case (all-caps)**.
 13. Save the `info` file with the changes to complete device sharing. Repeat for any other Bluetooth devices to share.
