I've sort of asked before, but am nervous about how to do this... I have a 10.4.1 bundled dvd that came with my ibook. I am wanting to burn a back up of it, as I loose and scratch the crap out of everything! Well, the dvd is over 5gb, and I have called apple several times asking them to send me a new disk, unbundled. The last guy that I spoke with said to simply download the combo version (10.4.3 combo) and burn it to a dvd as a bootable disk... Does that make sense? How do I do that in Disk Utilities? Which setting makes it bootable? Do I simply load the Disk Image and burn it, or open the Disk Image on my desktop and burn that onto the dvd?!? I'm totally confused. Please send help! Everything is crashing and going all kookie!
