Ubuntu 12.04 cannot detect Win 7 during installation

[serious7]

In the installation type section, I press "something else". It will show the device "/dev/sda" with no other information. Under device for boot loader installation drop down menu, it shows : "/dev/sdb and /dev/sda ATA Hitachi (1 TB)."

I have a 1 TB hard disk with 2 partitions. The other partition has Windows 7. I'm on AHCI mode right now. When I go to the home folder on Ubuntu, I can see a 189 GB Filesystem and a 811 GB file system (my 2 partitions). What's going on?

My ultimate goal is to dual boot both operating systems.

This is my fdisk output:
