I am attempting to reformat my iMac from the installation disk and so I restarted to computer, but now when it tries to reboot it brings up a screen that says:

You need to restart your computer. Hold down the power button for several seconds or press the Restart button.

I've done this several times but the screen keeps coming up and I cannot take the CD out of the drive now.

Does anyone know what to do?

I'm on 10.3.9 but going back to the original OS disk.

    Hi:

    If you can't boot form the install disk that came with the iMac, you may have a hardware problem.

    But first, which iMac model is this?

    Also, when you boot the iMac, are you holding down the C key?

    Make sure you have all peripherals and network cables disconnected (except the keyboard and mouse
    If you have more than one memory chip, try swapping them out to see if it will boot with one or the other rather than both.

    But do post back with more details/questions.

    Well, did you try swapping out memory chips yet?

    Can you clarify for us, please, whether the installation disk to which you refer is the original disk that shipped with the iMac G4, or whether it is the Full Retail Version or some other disk.

    Hi kpcvarner,

    I just wanted to let you know a couple of things as I see you are already receiving help from cornelius, et al.

    Try restarting the computer while holding down the mouse. This, hopefully, will eject the disk if it is still stuck in the tray.

    What you have experienced, in case you are not aware, is referred to as a Kernel Panic.

    See: "What is a Kernel Panic? (Mac OS X)"

    Also, there are some excellent troubleshooting steps you can take that are found in Dr. Smoke's, of the X-Lab, FAQ Resolving Kernel Panics.

    hope that helps some,

    Sorry about the delay.

    OK to reset PMU.

    Try booting from the Apple Hardware Test disk that came with your computer and run all tests in a loop by holding down Command + L during the tests.

    If you are not able to boot from the optical drive, try booting into Safe Mode by holding down the Shift key immediately after the chime.

    Let us know how it goes.

    Glad you got it resolved. That is why I asked about the disk you were using. Only the last of those iMacs shipped with 10.3.1. The earlier ones shipped with 10.2
