got a hand me down iMac with both osx 9 and 10.4.11 on it. tried to set up airport on it but it shows no airport at all in 10.4.11 so I went to start up disk to see if it was in on the 9 partion and everything I clicked on says missing something or other or not able to find so I thought well I would use disk utility and see what it could do for me it did it's thing and when done showed lots of problems so I clicked repair...when it was done it says everthing was repaired do you want to restart your computer? clicked yes. came back with a flashing finder folder with a ? mark!! Problem is the computer has no disks that came with it so what if anything can I do???? please help I also have a iPhone and now this is my only computer and I have no way to use iTunes for it.....
