Mint wont appear on GRUB

Sorry if it is duplicated, but i didnt quite find my problem.

I had (and still have) Windows 7 and Ubuntu 11.04 installed, then I attempted to install Mint 14 Cinnamon 64-bit. The instalation went fine, I created a new partition from free space of 100GB all dedicated to root, selested this new partition (sda7) to the `device for boot loader instalation` option, installed and reset the computer. Now, the partition I created still exists, but wont apper on GRUB, the GRUB is the same old Ubuntu GRUB I`ve always had, anyone knows the issue (questionmark)

You will need to boot from your usb/dvd and go into terminal.

Likely hood your windows boot will be in the first partition.

This is what I use when making changes.

sudo grub-install /dev/sda
sudo update-grub

As simple as that, thank you!
As I didnt care about which GRUB I'd use, I used the commands on my Ubuntu and it included Cinnamon.
