Extracting CD boot loaders

[T o n g <mlist4suntong@yahoo.com>]

Hi,

Anyone know ways to extract the CD boot loaders under Linux?

The reason that I'm asking is that, many .iso files come with size much 
less than 700M. So it would be a waste of CD spaces to burn them as-is -- 
I want to add more files to them (then pack them up again as iso) before 
burning them. So the most important step is to extract the CD boot 
loaders (mainly for Windows based bootable .iso images), so as to make it 
bootable again.

Thanks
