So I tried to get rid of my Linux partition first by restoring the MBR, but ended up with this. I installed Partition Magic to fix this, fired it up and sure enough, it detected some errors in the partition table, but ended up crashing for some unknown reason. I then loaded Windows' Disk Management and the last thing I saw was that I had a single unknown 120GB partition. Long story short, I ended up losing 40GB+ of music which I had been collecting since 1999, not to mention semi-valuable information. Oh well.
