Usually, you'd want your boot partition (part 3, and maybe part 4, in your case) to be primary partition. From your list, it seems part. 2-6 will live inside part. 1 extended? (But maybe you've configured it differently?) Also, Windows cannot live inside a Linux extend partition, I think.
Typically, I see this kind of setup when I partition:
5: /home (inside extended)
6: [swap] (inside extended)
