Good evening. I'm here with a unusual question if I'm not wrong. I have had downloaded 'Hiren's boot cd' which is a cd of freewares, now the downloaded format is an iso, I know onething just burn that iso file into a cd and that just works. In this context my question is how I can retain that iso's bootable nature and add some file/s to that iso at the same time? Is there any software to make it possible.
