Look when I restarted then I got a panic when I saw some text run on the leftside of the screeen and with black color behind it like in terminal. And I didn't understand a shit!

, and there was no way to get out that it my situation and same thing when tryiong to re-install the system, then I put the Cd in the drive and restarted, and then the ALT key and selected the Jaguar to boot from and then reinstall the system
Now some Hours after, with some sleep It was finnished, but when I trie to select instalation disk (my origin HD) it said that it was a never version so I made the alternative "Install The old system 10.2 and save the other system map and copy the settings etc". Now when it is finnished and wotking, can I delete the "Previous System" which it is called?, And how do I do it in terminal

, don't wanna screw anything now, hehe.
Anyway thanx for the support!.
