Comment 6 for bug 619579

1.) I would highly recommend keeping your computer up to date. I'm guessing maybe you shut down or something while it was running? I've helped a few people who powered off during an update of drivers or other core things, with nasty results. To be on the cautious side, open a terminal in Applications -> Accessories, run "sudo apt-get update", then run "sudo apt-get upgrade > ~/apt_log". The first command will check for updates, and the second one will apply them and log itself. If there IS a specific package that's causing issues, we'll know about it.

2.) You can open GParted (I'm pretty sure it's installed by default) under System -> Administration to take a look at and edit partitions. However, you do have only one Linux partition.

3.) I'm not sure why your Windows partitions are showing twice. Perhaps take a look in GParted in case they have boot partitions or something.
