Windows 7 - How to Create a New Partition Using Disk Management

Windows 7 provides a fully-featured disk management tool which allows you to easily create and modify partitions and customize your hard disk in ways which were not possible in some older versions of Windows without the use of third-party software. Creating a new partition is a great way to better organize your computer. A separate hard disk partition acts as a separate hard drive in virtually every respect. You can, for example, have a partition entirely dedicated to backup or storing your movie or music collections. Having separate partitions is also better for maintaining your computer with programs such as Disk Defragmenter and Disk Cleanup. Instead of having to scan the entire hard disk, you can just scan the system drive instead.

Open your start menu and click on the Control Panel. Beside "View by" in the top-right of the window, choose small or large icons. Click "Administrative Tools" to open a new window and choose "Computer Management." In the left-hand side of the Computer Management window, you'll see a section called "Storage." Click on "Disk Management" in this section.

Before you can create a new partition, you'll need to free up some space for it by shrinking an existing partition. This does not delete any data. It only scans for free space and allows you to use it for creating another volume. Right-click on your system drive (normally "C:") and click "Shrink volume." Wait for Disk Management to scan the disk for available shrinking space. Enter the amount of space to shrink the volume by in megabytes and click "Shrink." If you find that the available shrink space is much lower than the amount of free space on the disk, you may want to run Disk Defragmenter to reorganize the physical location of the disk contents.

Wait for the shrink operation to complete. Once it's done, you'll see an unallocated space on your disk with a black band across the top of it. Right-click on the unallocated space and click "Create volume." By default, it will use the maximum available space for creating the new partition, unless you specify something different. Click "Create" and your new partition will be made. It will now appear in Windows Explorer.

Open your start menu and click "Computer." You should see the new partition. You can label it by highlighting the shortcut and pressing F2 on your keyboard. Type the name and press Enter.
