[ubuntu] Can I use the Extendex/Swap Space partitions?

view story

http://ubuntuforums.org – Hi: The HD is a 320GB size. Ext4 (/dev/sda1) is 307 GB, Extended (/dev/sda2) is 13GB and Swap Space (/dev/sda5) is 13GB. By that I understand that the Extended and Swap Space seem to be the same partitions, am I wrong? Now, if I boot with a Win boot CD, can I install it in that partition? I have a W7 running as virtual machine but some devices are not recognized, like the video capture, that's the reason why I need a "true" Windows running. Thanks (Hardware)
