Linux users create partitions to organize their data in an efficient manner. As easy as they are created, Linux partitions can be deleted to reformat a storage device and regain storage space.

In this step-by-step tutorial, you will learn how to delete a partition on a Linux system.

How to Delete Partition in Linux


  • A system running Linux
  • A user account with sudo or root privileges
  • Access to a terminal window / command line (Activities > Search > Terminal)
  • The fdisk command-line utility

Delete a Partition in Linux

Deleting a partition in Linux requires selecting the disk containing the partition and using the fdisk command-line utility to delete it.

Follow the steps outlined in the sections below to delete partitions in Linux.

Note: The fdisk command-line utility is a text-based partition table manipulator. It is used for partitioning and repartitioning storage devices.

Step 1: List Partition Scheme

Before deleting a partition, run the following command to list the partition scheme.

fdisk -l

In our case, the terminal prints out information about two disks: /dev/sda and /dev/sdb. Disk /dev/sda contains the operating system, therefore its partitions should not be deleted.

Listing the partition scheme

On the /dev/sdb disk, there is a /dev/sdb1 partition which we are about to delete.

Note: The number 1 in /dev/sdb1 indicates the partition number. Make a note of the number of the partition you intend to delete.

Step 2: Select the Disk

Select the disk that contains the partition you intend to delete.

Common disk names on Linux include:

Type of disk Disk names Commonly used disk names
IDE /dev/hd[a-h] /dev/hda, /dev/hdb
SCSI /dev/sd[a-p] /dev/sda, /dev/sdb
ESDI /dev/ed[a-d] /dev/eda
XT /dev/xd[ab] /dev/xda

To select a disk, run the following command:

sudo fdisk /dev/sdb

Selecting storage disk with fdisk command.

Step 3: Delete Partitions

Before deleting a partition, back up your data. All data is automatically deleted when a partition is deleted.

To delete partition, run the d command in the fdisk command-line utility.

The partition is automatically selected if there are no other partitions on the disk. If the disk contains multiple partitions, select a partition by typing its number.

The terminal prints out a message confirming that the partition is deleted.

Deleting partition.

Note: If you wish to delete multiple partitions, repeat this step as many times as necessary.

Step 4: Verify Partition Deletion

Reload the partition table to verify that the partition has been deleted. To do so, run the p command.

The terminal prints out the partition structure of the disk selected in Step 2.

Partition table reload.

Step 5: Save Changes and Quit

Run the w command to write and save changes made to the disk.

Quitting fdisk command-line utility and saving changes to the disk.
