    I'm running an intel iMac and tiger, and I'm trying to upgrade directly to snow leopard. But, when I put the installation disc into my cd drive, the icon doesn't show up on the desktop. My iMac just beeps every 5 or so seconds, then after a minute ejects the cd out. It can read all other cds, but the snow leopard install disk happens to be an exception.

    Any suggestions on how I can install snow leopard?

    EDIT: also, the snow leopard install disk doesn't seem to be damaged; it runs fine on my sisters leopard macbook.

    On the fence
    Try booting from the disk - hold the option key when you power it on and then select the disk from there. It will take a little while to boot, but it should work fine. You may lose some data though, so be sure to have a backup

    I've tried that, along with the force booting key combination, and it doesn't work..
