Using bluetooth keyboard in grub bootloader

Question

I want to choose between several OS's during startup. How can i manage this by using my bluetooth keyboard/Cellphone or at least my IR remote?

Answer 1

One solution is to boot the linux system first, and then add the boot once command to grub for booting another system the next time. This will take time, but works without any hardware.

Using keys via IR remote did not work so far.
