I recently re-set the administrator password on My G4 running Mac OS 10.4 Tiger. In order to do so I had to select the installation CD as my startup disk because it wasn't recognizing the original Tiger Disk 1 I have. I tried re-starting without the CD, holding down the 'C' to boot from the version of Tiger(installed on my computer) but all I get now is a screen with a Padlock on one side, a text field and an arrow button. Anyone who has seen this before will know what I'm taking about. I tired entering my new system administrator password and clicking the button but nothing happened. Does anyone know how I can get past this and re-boot using the version of OSX I already have installed on my computer! Thanks for your help!
