When I try to update to mac os x 10.2 or 10.3 on my slot loading Imac G3 I keep getting the alert "An error occurred. 'Startup disk was unable to select the install CD as the startup disk. (-2).'"
I have tried booting the computer holding down option, and the cd doesn't come up, and I have tried booting holding down c and it just ejects the disk after a few seconds.
please help!
