    Hey Guys,

    I'm trying to reformat my imac, but each time I begin rebooting the computer and holding down onto C, the computer doesn't recognize the CD. I currently have a MAC OS 10.4. Are there any other ways of reformatting?

    Thanks,

    R89

    If you have another Mac with Firewire at hand: Target Disk Mode


    Is the gray restore CD/DVD the one belonging to that Mac? Or what kind of CD/DVD are you using?

    Have you tried holding down the OPTION/ALT key during startup and get to the boot selector screen and seen, if the CD/DVD shows up there? If it shows up, just select it and press ENTER and see if that works.

    It should look like this, but only with one HDD icon and with one optical medium icon.

    Hold down the OPTION key at startup and select Mac OS X Install DVD.

    What happens if you insert the CD/DVD into the iMac while Mac OS X is running? Can you start the installation from there? Can you see the CD/DVD in System Preferences > Startup Disk?

    Can you try the same DVD in another computer.

    I click on the logo to get the installation started but nothing happens and I don't see the CD/DVD in the startup disk. I see "Network Start Up" and "Mac OS X 10.4.11 on Macintosh HD"

    Seems like it might be an issue with the DVD itself.

    Is there any way of replacing the CD or should I buy a newer OS?

    You're better of buying a new OS

    If it is an x86 (Intel) iMac, you can get Snow Leopard for 29USD.

    If it is a PPC iMac, you may be able to get replacement restore DVDs from Apple for about 15/30/50 USD.
