Grub does not pick up Xubuntu after installing Windows 7, what is the reason?

Question

Windows

I have Xubuntu.
Wanted to put the Seven.
Put.
Useful to restore Grub.
At first, I did not want to.
Restored the download of xsubunty via usb live.
Through it already updated the hornbeam.
But, in the hornbeam there are only seven, restoring the seven, memory tests and "additional features" =( booted again through live, and through chroot started restoring, but at the end when I entered sudo update-grub, he issued everything except xubunt.
How can to load Xubuntu into a hornbeam if he himself does not want to?
