Cannot install new OS on internal DVD drive
I tried to upgrade my operating systemm from Tiger to Leopard. The computer or DVD drive did not allow the installation to complete. It had to be aborted, and now the computer will not boot up properly at all. It starts up, The apple symbol and a turning wheel appears, then the screen goes black and it starts up again, and the same thing happens. I end up having to just shut down the computer.
I was able to get back to the installation window, by holding down the "C" button while it rebooted. It then asked me to reinstall Leopard. After a short time, I got a message on the screen accompanied by a yellow triangle with an exclamation mark inside it. The accompanying comments said that the instalation had failed, and the disc may have been damaged, yet when I took the disc to a local computer store, they were able to successfully install it on one of their machines.
