Linux doesn't recognize windows on installation

I want to install Linux besides my Windows 7. But when I get into the installation menu, it tells me that this "pc doesn't have an OS installed". Although I already have a Win7 installed. I have 5 partitions from the same disk on my PC, but even testdisk shows only one partition.

I googled for it 3 days, and no solution is right to me. That is why I ask here. I tried when installing ubuntu and centos, and both of them don't show me the Win7.

this is what sudo fdisk -l gives
