Hello and I hope you can offer some assistance! I have a ruby red G3 iMac, and yes- i know it's ancient. So ancient in fact that it lacks the dvd drive neccessary to use the tiger dvds. A worker at an Apple store told me if I had access to a Mac *with* a dvd drive, I could install Tiger onto my Imac using the other Mac's dvd drive if I linked them with a firewire cable. I got the cable, got the two computers in the same room, plugged them in, restarted the ibook that had the dvd drive and held down the "t" key, and sure enough, my imac understood, and allowed me to begin upgrading. It had me pick a language, and then told me that Tiger could not be installed. Now the computer blinks the mac face and the questionmark file repeatedly and won't start up anymore. :-( HELP! please!! Is there anything I can do to get Tiger installed on this iMac? Is the hard drive dead? Is there anything I can do to make it start up again, since Tiger didn't even start to install? Can you offer me any advice? Thank you all so very very much!
