Hmmmmm.. isn't the system reserved partition suppose to be at the beginning of you hard disk? I mean, before the actual partition on which windows is installed. I think ubuntu concludes from that, that there isn't any other operating system installed on your hard disk rather than you or someone else (maybe the manufacture) created thise unusual partition table.
You have two choices here: If you bought you PC this way then you should keep the current table because that way you have the option of restoring and repairing the windows without using any installation disks. Which is more than just handy. But once you change anything it gets really difficult for you to restore back to that state.
But if you or the previous owner messed around here than there is not way around of manually creating an ext4 partition under the 'something else' option. But on the other hand: if ubuntu wasn't able to detect your windows partition before the installation it probably won't detect it while installing and updating the grub2 boot loader. Which means you won't be able to boot you windows at all.
I would suggest getting yourself some other (newer) version of ubuntu (13.10) and see if this one is able to detect the operating system.
If you have another (external) hard drive than also consider installing ubuntu on that one rather then messing around with your preconfigured OEM system.
