I have a Raspberry Pi 2 B+. I have a wireless mouse and a wireless internet stick. My keyboard is also Bluetooth but without an adapter. I can use it only when i type in a code that is needed to connect the first time. But I am already stuck in bios so how can I navigate with only the mouse? I bought this keyboard because it does not require a cable but I forgot that you cant use it at the beginning. So I am looking for a solution. I have a laptop. Can I use my laptop to configure everything so I can use my keyboard on the next boot? You guys know how this work? I am a beginner.
