dual boot - Ubuntu 12.04 LTS installer does not recognize Windows 7

I have been struggling with this for about 10 days with no luck. So after numerous installs of both OSs I now feel I need some help. I know there are many versions of this question posted already but none has worked for me so far.

My system has 3 HDDs (2*TGB, 1*250GB)and 1SSD and I want to install windows on the SSD and Ubuntu on the 250GB HDD. I also want the windows 7 swap file on a partition on the 1st 1TB HDD (correct me if I'm wrong but I think having the swap file on the SSD is not a good idea) and 3 partitions on the 250GB HDD: Root, Home and Swap. The second 1TB HDD is contains loads of files I really must not lose.

Currently, I have installed windows 7 on SSD but when I try to install Ubuntu 12.04 alongside it, windows is not recognized so I don't get that option. In the past couple of days I did have both working but I couldn't get grub to see windows and had to switch using UEFI.

EDIT-
Using GParted, I can see the screen bellow:

I am not sure what the unknown file system on sdd2 is.

Thanks a lot in advance.

you might just have to save your data to a backup disc and reformat the drive windows was on. The Ubuntu installer cant read some windows and mac filesystems.
