    hey there,

    so i go to use onyx and verify the startup volume or whatever terminology it uses (i'm more proficient w/ mobile stuff then computer software, fyi.)

    this points me to disk utility to fix the startup disk, but when i do, i get this. (look at the screenshot.)

    what, if anything, will fixing it do for me? and how would i go about fixing it?

    thanks,

    ron.

    You must start up from the DVD Install disk, as you can't repair the disk you are starting up from. After choosing a language, do not continue with the installation, but rather pull down the Utilities Menu, Disk Utility and try repairing the disk.

    Absolutely! Your internal disc can't repair itself!

    In other words, do exactly as the drop-down tells you. :)

    There are ways to get around the necessity to startup from another volume (such as the install DVD) to repair the system disk. An easy one is "Applejack" ( http://sourceforge.net/projects/applejack/ ). You run Applejack in "single user" startup mode.

    The app comes with excellent instructions and is much quicker for disk repair than going through the install DVD procedure.
