I have been trying for a while to install OS X Panther on my iMac G3, but when I open the install window and click restart, I get the following message: "An error occurred. 'Startup disk was unable to select the install CD as the startup disk. (-2).'" I have tried starting up in different modes (startup disk, etc.), but it always results in booting off the hard drive. I have an iMac G3 DV slot loading 400MHz and the install discs are retail versions. It is running OS 9.2.2 The firmware updates are done, and the CD/DVD drive works as I have tested it. I am also using all the original hardware (keyboard and mouse).
