If you are planning on reselling your old computer, it may be a good idea to remove all partitions from your hard drive to return it to its original state, the one it had when it came out of the store. Deleting partitions means that you will merge the existing partitions so that only one remains corresponding to the original hard drive. By deleting the partitions, you will restore its space to the original hard drive that was partitioned. Be aware that this guide only works with a Windows 7 or newer operating system. If you have an older operating system, you will need to purchase external software to manage your hard drive. On the other hand, all Mac operating systems should be able to do this.

Steps

Method 1 of 2: Windows

Unpartition a Hard Drive Step 1

Step 1. Back up any data that you want to keep still present on the partition

In order to be able to erase hard drive partitions, you will need to delete all data on the hard drive. See our article: How to Back Up Data for more specific instructions on the subject.

Step 2. Open the Windows Disk Management tool

On Windows, you will find this tool already installed. This utility will show you a list of all the drives and show you the partitions present on each of them. You can launch this utility by following either of these two methods.

  • Press the key To start up, type "compmgmt.msc" in the search field and press Entrance. In the options on the left of the "Computer Management" window, click Disk management.
  • Open the utility Disk management directly by pressing the key To start up, writing "Disk Management" and pressing Entrance. The “Disk Management” window should appear.

Step 3. Delete all data present on the partition

In the “Disk Management” window, you should see a list of Disks that start with Disk 0. The drives that are associated with each disk will be shown horizontally.

  • Right click on the partition you want to delete, then choose Remove volume in the menu. Find the original name of the hard drive, the one it had when you partitioned it. This operation will delete all data from that partition, which is the only way to delete partitions from a hard drive.

    • For Windows 7 and Windows Vista users:

      right click on the same partition and choose from the menu Delete the partition.

  • You should now see the partition as unallocated space. The score should have a black bar above its name, while other scores should have a purple bar.

Step 4. Allocate space to make it to the partitioned hard drive

Allocating space to return it to the original hard drive will remove space in the partition and give it back to the original hard drive. The original hard drive will, in a way, absorb the partition. If the hard drive that has been partitioned is called C, right click on C and click Extend the volume in the menu.

  • On a Mac, if your partition is managed by bootcamp, you should have trouble with this. Try to recover partition manager software for Mac.
