Sorry for the simplicity of this one, guys. I have UltraISO and I know how to open Hiren's Boot CD ISO and look at the files. But I still don't know exactly where to insert my own programs and data files. What I want to do is to take the Hiren's ISO, which is quite small, and to still use it as a bootable CD. But I don't want to waste all that extra space on the CD, so I'm hoping to add my own programs as well, plus I'd like to add some of my data files. You know, to fill up the CD and make it extra handy. So, once I'm looking at the opened Hiren's ISO file (using Ultra ISO), and I have all my own stuff ready, exactly where do I go from there? Is there a category or a special location? Thanks lots.
