    I tried to install windows 7 on it and the screen went black and now it comes up with
    No bootable device -- insert boot disk and press any key
    I can't get past this screen I can't eject my windows 7 disk to put the Mac OS X disk in and if I press any key nothing happens

    I think it's broken and I can't afford to buy a new computer
    Please help

    IT IS NOT BROKEN.
    When powering up the iMac hold down the OPTION/ALT key to get to the boot selection screen and choose Mac OS X ("Macintosh HD") to boot from and press ENTER.
    Then when logged in go to System Preferences > Startup Disk and select the volume with Mac OS X on it.

    Then use Boot Camp Assistant to remove the Windows partition and use it again to create a new one and try to reinstall WIndows again. Don 't use Disk Utility to erase the Windows partition.

    It is not really complicated as shown below.

    I had the same problem, a bit of googling always helps though.

    If you want to try again, follow the instructions here, carefully and to the letter! http://support.apple.com/kb/TS3173 and you'll have win 7 running in no time.

    Also if the drivers don't burn for you when starting bootcamp you can find them on the snow leopard disk, you must have those drivers. Also make sure you have a USB mouse handy.

    The first time I used bootcamp I almost cried when the same thing happened to me lol. I'm not the type to read directions going into something like that and I like to learn from trying different things. It was a while until I found out you had to insert the OS X disk for windows drivers lol. I remember when BC burnt a CD for you before install.

    No, it's not like you screwed it up. Don't feel bad ;).

    Black screen during Windows 7's install likely means W7's DVD doesn't have some generic display drivers.

    You just need to faff about with a USB drive. Once you plug that guy in with the files on it, normal service resumes.


    If you even have a kernel of curiosity, I'd urge you to try once more. Macs are resilient.

    I had the same isue with my i5 iMac after my Windows 7 install went pear-shaped.

    Not all the time, but occasionally it would happen on boot up and just sit there showing that "No bootable device -- insert boot disk and press any key" screen, instead of booting into Mac OS - even though I'd selected the correct boot disk in the Startup Disk manager.

    Simply enough though, I stopped it doing this by resetting the PRAM - as according to the Apple website, this resets startup disk preferences.

    :)
