I've already installed ubuntu 12.04 in Virtual Machine but whenever I shut down the machine and open the Virtual Machine again it keeps asking to install it again?
Any idea how to solve this problem?

You have to disable the CD/DVD option in virtual box settings or changing the boot-order to hard-disk as the first option will make you to boot into your installed Ubuntu OS.
On your virtualbox right-click on the Ubuntu virtual machine and select the Settings option.
Go to system tab and change the boot-order like in the below screenshot.And finally select OK option.
It sounds like your virtual machine is booting from the installation media.
In virtual box go to your virtual machines configuration and ensure that you remove the live usb / disk image from the available devices section.
