Ubuntu 6

In the world of system administration, one of the most common tasks is managing disk partitions. Whether you’re setting up a new system, optimizing an existing one, or troubleshooting, knowing how to properly resize and move partitions is crucial. One of the most popular tools for this job is GParted, a free and open-source partition editor. In this article, we’ll guide you through the process of resizing and moving partitions in GParted.

What is GParted?

GParted, short for GNOME Partition Editor, is a graphical front-end for GNU Parted. It’s a powerful tool that allows you to create, resize, move, and manage disk partitions on your system. The user-friendly interface makes it accessible for beginners, while its robust features cater to experienced users.

Preparing to Use GParted

Before you start resizing or moving partitions, there are a few things you need to do.

  1. Backup your data: Resizing or moving partitions can potentially result in data loss. Always ensure you have a backup of your important data before you start.
  2. Unmount the partitions: GParted cannot work on partitions that are in use. If the partition is mounted, you need to unmount it.
  3. Boot from a liveCD or liveUSB: If you’re working on the partition that contains your operating system, you’ll need to boot from a liveCD or liveUSB. This will allow you to work on the partitions without them being in use.

Resizing/ Moving Partitions in GParted

Once you’ve taken the necessary precautions, you can proceed to resize or move your partitions.

  1. Launch GParted: Once you’ve booted from the liveCD or liveUSB, launch GParted.
  2. Select the partition: In the GParted window, select the partition you want to resize or move.
  3. Choose the action: Right-click on the partition and choose ‘Resize/Move’ from the context menu.
  4. Resize or move the partition: In the next window, you can either enter the new size for the partition or drag the partition to the desired size. To move the partition, simply drag it to the desired location.
  5. Apply the changes: Once you’re satisfied with the changes, click on the ‘Apply’ button to execute the operation.

Understanding the Terminal Commands

During the process, you may need to use terminal commands. Let’s understand what they do:

  • sudo add-apt-repository ppa:yannubuntu/boot-repair: This command adds the boot-repair repository to your system. ‘sudo’ is used to run the command as an administrator.
  • sudo apt-get update: This command updates your system’s package list.
  • sudo apt-get install -y boot-repair: This command installs the boot-repair package on your system.
  • boot-repair: This command launches the boot-repair tool.

Recreating the Grub Bootloader

After resizing or moving partitions, you may need to recreate the Grub bootloader. The easiest way to do this is by booting again from the live USB and installing boot-repair. You can do this by running the above commands in the terminal.
