Okay, I decided to do a complete fresh install. I booted from the DVD, went to disk utility, told it to erase the system drive, it said it did, but it didn't. I can't get to a place from which I can reinstall the OS. If I go to startup disk and choose the DVD, it doesn't boot to it and my entire system is still here, nothing has been erased. If I double click on the DVD in finder, it opens and if I choose Install OX S and applications (or whatever that says), the window tells me to click the restart button to begin installation, but if I do that, it just boots up normally again. What's going on?
