Please answer my doubt..
Suppose your PC do not have any OS installed.(It has bootstrap loader).
1.  What will happen as an when you turn ON the system? Will it display
2.  How to print a hello on monitor without any OS?
3. How to use computer or operate anything without any OS? If no OS is
there, then what does it use for user interface?

What is the case for above questions when there is no bootstrap loader also.
