I managed to upgrade to Ubuntu 14.04, but then when I boot the system, it boots but with the version 12.04 kernel. I checked the /etc/default/grub and /boot/grub2/grub configuration and everything seem okay. But still I cannot boot the new kernel. I tried to get into boot menu to select the booting kernel but I was not able to get to it. I tried pressing SHIFT and ESC and still the boots with the old kernel. Any help with be very very appreciated.

First boot with the old kernel. Open a terminal.
Make sure your system is updated by running:
sudo su; apt-get update; apt-get upgrade
If you are sure you have the newer kernel, run
sudo update-initramfs -u
To create a new initramfs image. Now update GRUB with the command
sudo update-grub
GRUB should have recognized the newer kernel now. Reboot and you should automatically use it. Just to make sure, run uname -a to see information about the system and the kernel.
