May I make a suggestion?

For this kind of purpose, I use hexl-mode in GNU Emacs.

This mode lets you edit a binary file by modifying hexadecimal values in
the left part of the buffer and seeing the result on the right part of
the buffer: quite neat in my humble opinion :o)

Guess it would work with a MBR, with the precious help of dd, of course...

Have a nice day,
