then after installing daemon toolls, a virtual drive will appear in the my computer other than the dvd burner,,, in this virtual drive u can mount any image of the cd's...just as if the actual cd is inserted ...
so u can mount the image using the daemon tools after burning all the images on the dvd and ur job will be done..
