partitioning

I got my brand new Dell Inspiron 14z yesterday, but failed to install Ubuntu. I can boot from a USB stick, and it works well. When trying to install, I confirm that the laptop is connected to the internet etc (as in the 2nd picture in the installation guide: How do I install Ubuntu?). When pressing "Continue" I do not get the question on installation type (alongside/replace/something else). Instead I get a window where I can select partitions:

// Picture removed due to low reputation...

The problem is that I can only select sdb in the drop drop down box, and I can do do nothing with sdb (like adding partitions etc).

The main disk (sda) is partitioned using Gparted the following way:

// Picture removed due to low reputation

As far as I understand from other threads on askubuntu, this should work...

What can I do to install Ubuntu alongside with Windows 7?

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
