Windows 7 is not show in Grub2 after Boot-Repair

Windows 7 is not show in Grub2 after Boot-Repair

I asked this question in AskUbuntu, but nobody answered. So I ask here. My
Windows 7 is not seen from GRUB2 after Ubuntu installed. I have used
Boot-Repair to fix it, but Grub2 can only see Ubuntu. If I restore the MBR
with Boot-Repair, windows 7 boot automatically without Ubuntu. Is there
any way to let Grub2 display both windows7 and Ubuntu? Here is my boot
information from Boot-Repair
The following may or may not help, but when I run
sudo fdisk -l
It says Partition 4 does not start on physical sector boundary.
