    Hey guys
    I have a very big problem and I need your help
    so here's what happend:
    I was trying to install ubuntu on my mac
    so I did but the problem is that I accidentally deleted mac :(
    but that's not it
    when I was facing troubles in installations I putted my mac osx install dvd
    and then I made a big mistake
    I chose the network startup
    now my iMac only have Ubuntu
    and before it starts earth/globe flashing lasts for 20sec then it starts to boot up
    but the problem is that now I can't boot up from my mac cd :(
    I only can boot up the linux cd
    I tried pressing c but nothing happens
    it there anyway to fix this through the ubuntu or anything else ?
    thanks in advance

    Have you tried booting with the Option key held down? That should bring up a list of all available devices--optical drives, hard drives, network--and allow you to select one to boot from. Depending on what your Ubuntu installer did to the EFI setup it's possible that might not work, but try it first.

    Did you use rEFIt during the install? I didn't think it was supposed to do anything to the hold-C-key-at-startup feature, but it could be involved.

    Duff-Man says...try zapping the p-ram - hold command+option+p+rnat startup and let the "bong" go a couple times...then hold the option key and it should give you the available boot options, hopefully the osx disc should be one of them....oh yeah!

    Didn't work :(
    I guess I figure out what's the problem
    Maybe because mac is uninstalled and the only os there is ubuntu, the keyboard wont pair at startup
    So I may buy a USB keyboard to solve this problem
    I hope that it works
    I'll tell u if anything happened
    If u have other solutions please tell me
    Thanks

    My solution would be delete the entire drive and start from scratch.
    Or ask in the ubuntu forums they no more about what you can do from within Ubuntu to fix the problem than people here.

    Glad that worked out for you. Knowing that you were using a wireless keyboard would have been a helpful bit of information, since I've seen a number of cases, even without Ubuntu in the mix, where a wireless keyboard fails to initialize pre-boot to the point I can hold down a key to get EFI to boot from an alternate source.
