An .iso is a complete image of a disc, the same way .img files filled up a floppy drive. Whether dvd or cd must realize the following: DVD R + or - is Read-only as in burn complete image, write one time. DVD RW is Read/Write, needs to be formatted before write, can do multiple times. ISO is Read-only, use a DVD R disc. Read-only means Write Once! The drive could be: cd-r, cd-rw, dvd-r, dvd-rw, will read any of these types. Writing at slow speed a good idea. R e b
