    DU tells me 'the volume macintoshHD needs to be repaired'
    error: the underlying task reported failure on exit
    volume needs repair

    so i need to startup from my install disc
    ok i've had to do that before

    but some resources say to restart while holding down the 'C' key, others the 'Option' key.

    i think i've done it before using the 'option' key. not sure now.

    my question:
    -what's the definitive one to use for this?
    -and what's the difference? (i've read what they do differently but don't really understand the difference)

    my AppleCare just ran out and i understand it can't be renewed. is there another option available? or is apple's 'pay per incident' the only way from now on?

    thank you all!
    this is an invaluable forum

    'C' boot from optical drive.

    "Option" show the boot loader which includes the optical drive. ;)

    so it doesn't really matter then
    the 'option' just adds another step in this instance
    thank you

    You need to boot while holding down the c key ( insert disk ), the option (alt key) like Eidorian stated brings up the bootloader ( ie if you have two OS's installed say OS X & XP )
