I just bought an old wallstreet powerbook. It came with 32mb of ram and a 4gb harddrive running os 8.5. I installed 512mb of ram, and everything worked fine. Then I got a 60gb hard drive and put it in. When I turn it on I get a gray screen with a little disk in the middle with a question mark on it. I have a copy of os x 10.3 (panther, I think). What do I do? I thought I would just put the first disk in and it would read it and go from there. It just spins furiously for a few minutes and then shuts itself off. As I'm sure you can tell I've never done this before, I've only installed a newer version of os, not started from nothing. Help would be much appreciated.
