about why the startup page has only one system startup item after installing dual systems __system

A few days to help students under the Win7 installation Liunx dual system, the installation process is smooth, but the installation completed on the startup page did not appear win7 startup items. After consulting a lot of information, we finally solved the problem. In this small remember, hope can help others. (This is my first blog).

An explanation on the Web, as follows:

However, the real operation is not easy, had to use the scalp to find their own way. The overall reason for this is the grub boot issue, to update it. But finding the newer places is one of the biggest headaches.
