This brief tutorial is going to show you how to resize your primary local disk or partition in both Windows 7 and Ubuntu 12.04 (Precise Pangolin). Even though these methods are different, the goal is the same – resizing your primary partition in order to create new ones. Most computers today have only one hard drive and one primary partition that is being used by the operating systems – both Windows and Ubuntu.

So, in order to create additional partitions from the existing primary partition, you’ll need to shrink or resize the primary partition. This is true for both systems.

And although these systems are different (Windows 7 and Ubuntu 12.04), they’re almost similar in many functions. Almost everything you do in Windows 7 and be done in Ubuntu 12.04. Without wasting anymore of your time, let’s get going.
