I installed Boot Camp on my MP today, and partitioned 32GB on a separate harddrive. It all went just fine, until I rebooted into OS X again, only to discover all my settings were gone, my account was fresh, my home directory - gone (well, replaced with a "standard" home directory, or something). So I'm wondering, could Boot Camp have messed something up, or could it be that I was using FileVault on my account? I tried turning FileVault off now to see if my home directory would reappear, but it didn't. Anyone with similar experiences?
