I got confused with boot and root! Thanks for correction. Usually boot
disk is mounted at /boot. Your boot disk could be same as root disk (in
this case there would not be anything mounted at /boot but just a
directory).

I don't think there is a sure way to find out your boot-loader disk in
every situation as your boot-loader disk is not needed after boot.

Thanks, Malahal.
