I'm trying to figure out if there's a way to use my Bluetooth keyboard when I'm in the BIOS or boot loader. I have a Bluetooth keyboard that connects directly to my computer without needing a dongle. Is there a specific Bluetooth dongle or device out there that can connect with my keyboard before booting up, so I can use it in those early system stages? I came across a USB Bluetooth adapter that supports HID Proxy which might work, and I also found a Raspberry Pi Zero project for building your own solution. I'd love to hear any insights from you all!

Have you thought about physically connecting the keyboard to your motherboard? That would ensure it works during boot.
A cheap Bluetooth dongle from Amazon should do the trick! It can connect your keyboard to the dongle first, and from there, you can use it with your PC, even at boot up.
You might want to consider getting a keyboard that comes with a traditional wireless dongle. Although it won't be Bluetooth, it typically connects better in BIOS situations. But this would mean you'd need to switch keyboards. Which model do you currently have?
Bluetooth operates on similar frequencies as WiFi, so it's a bit tricky. It relies on chips and firmware that usually only come into play with an OS. The best bet here is to go with a keyboard that uses a dongle, like others have mentioned, for full functionality during boot.
Unfortunately, Bluetooth keyboards don't function in BIOS because they rely on a connection that's only available at the OS level. In theory, you could build something using an Arduino that connects your keyboard and then acts as a USB keyboard. But if you're looking for simplicity, just grab a keyboard with a non-Bluetooth 2.4GHz dongle instead.
