Yesterday I was using windows on my iMac using bootcamp and it was working fine. Today when i tried to boot up in Windows it didn't work so i went to System Preferences>Startup Disk, and I didn't see BOOTCAMP option there!! Just to check, I opened DiskUtility and the partition which was on was formatted!!. I can't figure out what is wrong because no one except me uses this machine. Is there any fix to this. I'm really pissed off right now. -.- (Hope it makes sense to you.
