How to get the GRUB using virtualbox?

Question

I have ubuntu-12.04 on my virtualbox and I have two kernels in /boot (old and new). When I restart the vbox no grub appears to choose! and the result of cat /proc/cmdline still shows the old kernel is running.

I tried pressing shift but it also does not work!

You have to know that VirtualBox is just Virtual, so many things can be different.

Reboot your virtual machine and when you see Oracle's logo , click the screen (focus there) and then hold down Shift until Grub menu appears.

Edit /etc/default/grub:

gksudo gedit /etc/default/grub

And add a # in front of GRUB_HIDDEN_TIMEOUT=0

Finally, apply with:

sudo update-grub

Note: If you plan to change GRUB2 shell keyboard layout, forget immediately about using the Shift method. It may be normal that terminal_input at_keyboard make this key not work anymore.
