Edit bootable CD

[nlsn]

DAEMONToolsPro4350308 (advanced Trial) + Windows 7.

After ISO edit to add file, the dialog indicates image will not be bootable. Could you point me to the forum thread to discuss this? or perhaps I need a different product or add on procedure, Nero or such.

What does the image contain? An Operating System?
Maybe take a look at this program:
