In preparation of installing ubuntu 12.10 for dualboot along with pre-installed win7, I encountered a problem: that the intaller, upon reaching the point where I have to choose a partition for intallation does not see any thing at all, and freezes. After some google-fu, I figured out that I can learn something by the following command.

Trouble is, I cannot really tell what I need to do to make the installer see the partitions that I created for it.
Thanks.
Ps. I use a HP laptop with an hdd and a small ssd.
