Here's the rundown of what I'm using. Macbook pro I bought a couple years ago, 2.2 intel core 2 duo, 120GB HD, 2GB ram, OS X leopard. I'm dual booting with Windows XP. If more hardware specifics are needed, I can post those. Recently while I was using my comp, the battery died while I was in the windows partition, and upon next trying to boot into OS X, the following happened. The Apple logo comes up, then the icon starts spinning underneath it. And that's it. That's as far as it gets. It just sits there until I force shutdown the comp. Windows XP stills boots perfectly fine. OS X is the default boot. Now, upon further investigation I learned that one of my friends pranked me by installing a fork bomb on OS X. He told me to boot into safemode, since it would stop any log on processes from occurring, and just delete the file. UNfortunately, this didn't work. I tried booting into safemode, and the result was that the spinning icon took longer to show up, and when it did, it stayed there for a while before the computer then automatically shutdown. This leads me to the conclusion that the fork bomb is not the cause of my problem. I don't have the OS X.5 CD here on campus with me to boot from, so until I get that, do you guys have any suggestions for me? I mean, there doesn't seem to be much I can do, since I can't access any files, other than the idea that I need my harddrive reformatted or something. I've tried just leaving it alone for a day, electronics like to work if you just don't use them sometimes, but not in this case.
