I've partitioned the hard drive about two weeks ago, but when I try to switch to windows, it always gave me a blue screen filled with some gibberish I don't really understand. One time, another screen followed the blue one stating "disk failure."

Should I re-partition it? I've already taken it to the apple store, but they didn't find anything wrong with the hard drive. Then they asked me to take it somewhere else, because they said they could only help me with mac problems, not windows.
