Can't startup to desktop with Jag CD???

Ok is it just me or is it the CD, is this the first time that Apple has released an OS that you can't do a complete startup on?
I put in the Jag 10.2 install disk that I bought from the Apple Store nearby, everything is normal UNTIL all I can get is the installer!?! No desktop. No other options other than to quit the installer and reboot. Which if you're trying to use this as a t/s option it's kind of useless.
Please tell me I'm not the only one...
