This comment is for any skeptics that are inclined to over-complicate things and do all the crap (i.e. mounting an ISO image, running SD4hide, etc) listed on this particuar thread. Just do as Joosekey advises. If you have the multi language cd, just name it: ROS_1.7.9. I did, and I did it w the cd writer that comes w XP. All the complicated steps not required.
