So this is only remotely related to Kali, but what happened was that I wanted to boot the wrong Kali once (amd and not intel) which obviously didn't work and the second time, when I noticed this while setting the boot options in BIOS, I went with "exit and discard changes" to reboot the system.

Well, that's when my laptop keyboard stopped working. I tried restoring Windows etc., but it doesn't even work in BIOS anymore. USB keyboards work just fine.

Help, anyone?
