I'm trying to follow instructions at https://github.com/nbanks/bluetooth-dualboot linked from the bluetooth section in the Arch Wiki.
When I get to the section for "sudo chntpw -e SYSTEM", I get a key not found error:
> cd ControlSet001\Services\BTHPORT\Parameters\Keys

Key a477583cf3aa not found!I'm not too sure what I'm doing wrong or how to proceed. Any help would be greatly appreciated!
EDIT:
For whatever reason, I couldn't connect properly with the link key obtained from Windows. However, I was able to successfully connect by pairing first on Linux and then entering the key manually into the Windows registry.

Ah I see it's because the instructions are assuming bluetooth 5.1 and my device is not. I was able to get the link key by hexing the MAC address DWORD. However, I still can't seem to connect. Trying to connect through bluetoothctl gives:
