Install Ubuntu 12.04 LTS on VirtualBox
As I've recommended on the previous post, I prefer Ubuntu 12.04 LTS as there are some minor bugs in the latest Ubuntu. If you want to use Ubuntu as the primary desktop operating system, you should use Ubuntu 12.04 LTS. (By the way, LTS refers to Long Term Support). Listed below is the installation notes on installing Ubuntu 12.04 on a virtual machine.
On VirtualBox select "New".
Enter the name of virtual machine. Click "Continue".
Set your memory allocation for this vm. Click "Continue".
If you are creating a new virtual hard drive, select the hard drive file type. Select the default. Click "Continue".
Select "Dynamically allocated" and click "Continue".
Name the virtual hard drive and select the virtual hard drive size. Click "Create".
Click "Start" to start the virtual machine.
You need to select the start-up disk. Select the ISO image of Ubuntu 12.04. The system will launch Ubuntu.

Run the Ubuntu virtual machine and logged in. Under "Devices" Select "Install Guest Additions..". You can proceed from here.
If you encountered problem running the installation from the CD, click "Cancel" while trying to install the guest additions from the CD.
Open a terminal. Navigate to the CD folder under /media/VBOXADDITIONS.....
