    Boot Issues

    When I hold option or if I boot through refit I am given two options: Mac OSX and Legacy OS. When I choose Legacy OS I am taken to a black screen that says: Missing Operating System.

    I have played around with dual and triple booting and would like to return to single booting with Mac OSX.

    How do I get rid of this Legacy OS Option? Please be detailed in the explanation?
    Thanks in advance

    Below I've posted a partition report.

    can't you just remove refit ? Your mac should be able to boot by itself then I guess.

    Re: Boot Issues

    booting into mac is not an issue.
    The issue is the Legacy OS that refit thinks is there.
    If I remove refit and hold option while booting, an option to boot into windows exists, however this goes to the same screen that says: missing operating system.
    Im hoping to remove the cause of the bootloader thinking an operating system is there when it isn't

    Re: Boot Issues

    The second thread worked.
    I had to boot from the ubuntu cd.
    In the terminal I typed
    sudo dd if=/dev/zero of=/dev/sda bs=440 count=1
    I restarted and legacy was gone
    thanks for the help!
