I was transferring files to my Powerbook 3400c with the CD drive, before I accidentally bumped the power switch on my power strip and the computer shut off. Now, when I turn it back on, it boots to a happy Mac, and nothing else. I don't have the original installation media for this computer, but I have images I made of some of my old discs (Mac OS 8.5, and Mac OS 8.0). They are in a .toast format. I've tried burning these with ImgBurn by simply renaming them to .iso, and holding down C while turning on the Mac, but it hangs once again at the happy Mac screen. I have a PowerMac G4 running OS 9, but it doesn't have a CD burner in it. I have my main PC running Windows 7, and I have a Mac Mini G4 running 10.4.11. On a scale of 1/10, with 1 being flathead and 10 being torx, how screwed am I?
