    Hi. I'm working with a white intel iMac and want to install a new OS. However, i've run into some nasty hurdles.

    1. I can't manage to get the mac to receive keyboard input during startup. I've tested a brand new keyboard on other systems and it works fine, but none of the boot key combinations have any effect (can't even boot as target). The caps lock light won't even come on.

    2. This is the reason i need to control the boot with the keyboard: I'm getting a "no bootable device found" message. This is even when a new Snow Leopard disc is in. I've also tried other bootable discs. The internal drive was working two days ago, but seems dead now. I want to run disk utility from a disc and repair the internal disk, but i can't. I wouldn't even be able to with it as a target.

    3. The optical drives makes ugly noises, yet it does seem to be spinning the discs and i have had success reading from discs (prior to my unbootable situation).

    Any thoughts, anyone? Thanks!

    I would imagine that the problem is that you are using a Bluetooth keyboard. If you have access to a hardwires USB one that should solve your problems.

    How to fix it

    all you need to do is hold down the cmd button on the keyboard if its not an apple keyboard do the same but hold alt key
    make sure its a usb keyboard because the bluetooth ones don't work until a later sage in the boot up
    first boot up holding the cmd or alt then it will come up saying what do you want to boot of click macintosh HD and it will boot up

    to fix this from happening every time go into system preferences and start up disk and click macintosh HD

    Good Luck

    Totally forgot about this thread, sorry. It turns out the logic board was bad, replacing that fixed the issue.
