My Powerbook G3 is not working at all. First I had Panther up and running beautifully and then I was searching some files and realized oh maybe I deleted them so I stuck the installer in and clicked to install and then restarted the computer. Well, I did that and everything was going fine but then I couldn't reinstall I had a later version of Panther on it. Then I chose start up disk and chose my exsisting one and when I did that it failed to load. So I went to the installer disk again and partioned my hard drive and then went to repeat the process but it said unable to load OSX because a previous OSX has not been installed or something, but the weird thing is when I first got the thing like 3 weeks ago the first thing I did was stick the Panther disk in and it worked fine. Please help me!!!!!!!!!
