I'm having a little problem. I have an iMac G5 without a CD-ROM and I need to reset the administrator password and to do that I have to boot from the OS X CD. What I've done to try to work around that is create an image of the OS X Install Disc 1 and put it on my external hard drive. When I try to boot from the external (option-command-shift-delete), nothing happens and when I let go of the keys I end up in Safe Mode. What I think my problem may be is that there is other data on the external hard drive, so when OS X goes to look for the Install Disc, it sees everything else on the external so it makes the ISO file invalid. Do I need to find an external hard drive with no information on it to act as the Install Disc or is there another way I could/should go about this? Thanks to anybody in advance, this problem has been bugging me for weeks now.
