    Hey everyone

    It appears that I can't boot my OS X 10.5.8 CD, despite holding C. Option key. nothing happens, it just takes me to the log-in screen!
    note that I have windows installed on the same machine using Boot camp assistant.

    Here is how I did it, so if there is any thing wrong you can tell me.
    As soon as I press the power button, this screen appears:


    Then I choose which OS to load (using the keyboard).
    right after choosing the Mac and pressing return (enter), I press and hold C.

    I hope I can find the solution here. Because I already posted the same topic in 3 other forums, but I didn't recieve any help.

    You have to hold the C key right after pressing the power button, not after choosing the OS.

    I've never seen that screen before; looks like you did some mod to make the icons look like that? If that's the case then who knows what's wrong with your machine.

    What about Mac OS X > System Preferences > Startup Disk?
    Can your Mac boot via the DVD then?

    You have rEFIt installed, haven't you?

    Is the DVD the one that came with your Mac?

    Have you tried OPTION/ALT instead of the C key or OPTION/ALT or C right after the startup sound?

    As someone said earlier, you press startup command keys AS SOON AS YOU HIT THE POWER BUTTON, rather than after.

    How..and indeed Why did you install rEFIt?

    Thereby lies the key to the situation.

    I'm assuming it's screwed it all up, so remove it and you SHOULD be back to normal, however let this be a warning, that you shouldn't tinker if your not completely competant!

    But it's necessary to know how you installed it, before we can tell you how to remove it.

    As has mentioned the other possibility is your trying to boot from an OS that is PRE your machine. i.e if your laptop came with Snow Leopard, you aren't going to be able to boot from 10.5.8 !

    It's not me who installed it. The laptop was given to me by my Institute, and after I graduated they haven't removed it.
