Trying to upgrade form 10.5.8 and upon the first reboot, the DVD ejects and the upgrade will not continue. Prior to the reboot, the only message is that the installation will continue after it reboots but it never does. There are a bunch of pkg files in the MacOSX Install Data folder. Has anyone seen this before of do you know how to manually continue the installation? It's acting like the media may be bad but I have no other MAC to test it on and no access to other install media to test. I was able to copy the contents of the dvd drive to an external drive but unfortunately it won't let you install from that volume. Any thoughts?
