dual boot - Grub 2 detects incorrect partition for windows

Windows 7 is present on /dev/sda3, but grub 2 detects Windows 7 on /dev/sda1. How can I configure Grub 2 so that it will always point to /dev/sda3 for Windows 7, even if later on I do a sudo update-grub?



Windows 7 is present on sda3, but during installation it created a small 100mb partition as sda1, which Grub 2 is pointing to. But Windows 7 on my machine can boot from /dev/sda3, not /dev/sda1.
