Trying to use some of Drive Genius 3 LE's features but they require that you boot from a startup dvd. I followed the instructions to burn a dvd from install Lion app. I thought that I would choose it as my startup... boot up and then be able to choose my Drive Genius app and go to work. Since I've never done this before I obviously am missing a step somewhere. Everytime I reboot using the DVD it brings me to a screen that only gives me Lion utility functions... Install Lion, Install Time Machine Backup, etc. What is the magic trick to reboot and be able to use my apps? What am I missing? Any help is appreciated.
