Hello!

I want to know how can I develop a code in C or Assembly which will show a "Hello" message before OS?

When you have OS installed on your PC, Linux, Windows or ... (if OS makes difference for now I just need Hard disk which have Windows installed)

I want to show a message! Hello message there...

How can I do that?

Thanks from now!
Please provide some example codes and useful links for it!
