Installed Ubuntu 12.04 LSD alongside with windows 7. No boot menu

Question

I have installed Ubuntu 12.04 LTS 64-bit alongside with windows 7. During installation I choose Something Else and partitioned as followed:

And choose /dev/sda for boot loader installation

The installation was successful. I never get a boot menu from where I could choose the OS.

What is the problem?

You should install GRUB bootloader to /dev/sda not sda5.
I infact first installed it to /dev/sda but got the same problem.
You can try booting from a live CD, sudo mount --bind /boot <path to sda5>, sudo mount --bind / <path to sda3> then issue sudo grub-install /dev/sda, finally sudo update-grub2 and provide the output in your question.

Open the terminal and run this command:

root@penreturns:~$ sudo gedit /etc/default/grub

Comment line (add "#"):

GRUB_HIDDEN_TIMEOUT=0

It must look like this:

# GRUB_HIDDEN_TIMEOUT=0

Update your GRUB with this comand:

root@penreturns:~$ sudo update-grub

Reboot your system and you will see how the system will now stop at the GRUB2 boot screen.

Enjoy!
