I'm using a Powerbook running Mac OS X 10.5.6. I do not currently have access to the admin account. I have tried to reset the admin password using the original Install Disk that came withe computer. However, when I go to "Reset Password", and am prompted with "Select the Mac OS disk which contains a password to reset, my Macintosh HD is not listed as an option, only the Install Disk . Because of this, none of the user accounts on this computer are listed in the dropdown menu for me to select. How do I select the HD if it's not even there???? *cries*
