boot - Ubuntu installer doesn't detect partition on Win7 (Warning: Can't have a partition outside the disk!)

I tried to look it up on the forum but I can't find a solution.
I just got a PC laptop (I come from Mac…) installed Win7 and partition my hd in 3 parts, one for Win7, one unformatted for Ubuntu, and one NTFS for data.

The Ubuntu installer doesn't recognize the partitions though. What can I do?
My goal is to have a dual boot. Thank you so much!
