How to Partition Your Hard Drive

Petri IT Knowledgebase

Jan 6, 2009

A hard drive partition can allow you to easily test out new operating systems (like Windows 7 beta) or create a simple way to separate your user data from the operating system install. You can divide your hard drive into multiple partitions, some bootable, others not.

The main reasons for having separate partitions are:

to better organize your files
to separate system files, log files, cache and virtual memory from data files and programs
to create separate virtual drives for multiple operating systems • to protect or isolate groups of files to make data recovery easier

Step 1: Download and Install Partition Commander

To partition your hard drive, you’ll need a partitioning utility. We recommend Partition Commander from Avanquest (previously VCOM). You can find Partition Commander here. Once you’ve downloaded the program, run the install with the default options. You’ll need to reboot when the installation is complete.

Step 2: Start Partition Commander

Select Create Partition and click the Create Partition option in the main screen:

The Create New Partition Wizard will appear.

Choose the Next button.

Step 3: Select the hard drive where you would like to create the partition

Partition Commander will let you select a hard drive where you would like to create your partition.

In this example, there is only a single drive. Click the Next button once you’d selected your drive.

Step 4: Set the size for the new partition.

Drag the slider button to set the size for your new partition.

Once you’ve set the size, click the Next button to continue.

Step 5: Choose the OS for the partition you are creating

Partition Commander supports all common operating systems including Windows, Novell Netware, Linux, and different varieties of Unix as well as some less common operating systems such as BeOS, CP/M, and Pick.
