I have a Power mac that I forgot my master password. I am trying to boot the computer from the disc by hitting the "C" key after the bell and nothing. Does anyone have any idea's on booting from the 10.4 original disc so I can reset my passwords and move on with using my computer again?

Thanks

What are the specs of the Mac you are trying to boot from the 10.4 CD/DVD? Is this 10.4 Disc the one you used to install OSX on the machine?

Take it you are popping disc one in, rebooting, and holding down 'C' after the chime?

Note your PowerMac will not boot from the silver/grey system install discs from another Mac model.

The mac OSX 10.4 tiger is the latest updated software I put on the mac. I bought it at the apple store. Leget software. I'm use to bios. So this is new. I can only start the mac. Cannot get past login due to no memory of the master password nor keychain.

Back to my old 2.2GHz C2D MB after selling my MBP and wondering what my next Mac will be :)
Hold option as soon as you hear the chime until you see the spinning gear. Then select the install disc to boot from.

Try Option (alt). Or D. If it's a non-apple keyboard, these might not work.
