I've been attempting to install Mac OS X v10.2 onto my iMac G3 that I just bought off eBay. I purchased some installation discs and I get an error when I insert the "install disc 2" I believe I have bought upgrade discs and not a full installation disc but I am not able to find exactly what I need on eBay. Could someone provide a picture of the disc I need so I don't buy the wrong ones again? I've attached pictures of the installation disc I have and the error message. Thank you!
