I just booted into Windows and saw that there were some Windows Updates available and it asked me to reboot the computer however it failed to boot into Windows. So I restarted and tried to boot into OS X instead, but that didn't work either. So I put in the OS X install DVD and checked out Disk Utility. Turned out that all my partitions where screwed up. There were 3 partitions listed as Windows_ldm, with incorrect sizes (I had 4 partitions before). Long story short: I'm now reinstalling OS X and I lost everything I had on the drive, I think. I'll try some restore software once I've gotten OS X installed. A little pissed right now... How the heck can Windows F up the entire drive?
