I was having issues with my PowerBook G4 Titanium (667 MHz) running OS 10.3 (Panther), see
http://discussions.apple.com/message.jspa?messageID=5846471#5846471, so I zeroed and erased the harddrive before installing the original operating system, OS 10.1 (Puma). Using the Software Update feature, I updated to OS 10.1.5, verified/repaired permissions and the harddrive, and then updated firmware before proceeding to install OS 10.2 (Jaguar) using a full retail upgrade disk. The installation produced a kernel panic in the final stages, so I repeated the process from the beginning (zeroed and erased the harddrive, etc.). The second go-around, the installation hung up in the final stages (with 8 minutes to go, which went on for a good hour), until I received an Unexpected Error. (Exit Code 0). I restarted the computer while holding down the Option key to select the original OS 10.1 startup disk, and now my laptop starts up with the smiling mac icon and a crude black-and-white spinning sun. I used the Disk Utility feature to verify/repair permissions and the harddrive, but ejecting the Installation CD and attempting to start up still displays the smiling mac and crude sun.
I suspect the harddrive itself may be defective (at least that's what started this whole chain of events), but the Disk Utility verifies the harddrive. If it's not the harddrive (how else can I tell?), is there something else that may be impeding installation of OS 10.2?
My OS 10.3 is an upgrade CD, not a full retail installation DVD, so I am reluctant to try and jump from the original OS (10.1) to 10.3 without first installing 10.2. Or, is that possible?
Would I be able to install OS 10.2 using the full retail CD, or do I have to install the original, base OS (10.1) first?
I appreciate any advice the forum is willing to offer.
