How To Resize Your Root Partition in Ubuntu

Ubuntu 12

In this article, we will delve into the process of resizing the root partition in Ubuntu. This process can be useful if you’re running out of space on your Ubuntu partition or if you need to allocate more space to another partition. However, it’s important to note that resizing partitions carries a risk of data loss, so always back up your data before proceeding.

Quick Answer

To resize the root partition in Ubuntu, you will need a Ubuntu Live CD or USB and GParted. Boot from the Live CD/USB, launch GParted, identify the root partition, and resize it by right-clicking on it and selecting "Resize/Move". Apply the changes and reboot your system.

What You’ll Need

  1. A Ubuntu Live CD or USB: This will allow you to boot into a separate Ubuntu environment without using your installed Ubuntu system. You can download the Ubuntu ISO from the official Ubuntu website and create a bootable USB using a tool like Rufus.
  2. GParted: This is a free partition editor for graphically managing your disk partitions. It comes pre-installed on the Ubuntu Live CD.

Back Up Your Data

Before you start resizing your partitions, it’s crucial to back up all your data. This process carries a risk of data loss, and having a backup ensures that you can restore your data if something goes wrong.

Booting from the Ubuntu Live CD/USB

Once you have your Ubuntu Live CD or USB ready, restart your computer and boot from the CD/USB. You might need to change your BIOS settings to do this. Once booted, you should see the Ubuntu desktop.

Launching GParted

From the Ubuntu desktop, click on “Show Applications” at the bottom-left corner of the screen and search for “GParted”. Click on the GParted icon to launch the application.

Identifying the Root Partition

In GParted, you’ll see a graphical representation of your hard drive’s partitions. The root partition is typically the largest ext4 partition. It’s usually labeled as /dev/sda1, but this can vary.

Resizing the Partition

  1. Right-click on your root partition and select “Resize/Move”.
  2. In the “Resize/Move” window, you can adjust the size of your partition. You can either manually enter the new size or drag the slider to adjust the size.
  3. After setting the new size, click on “Resize/Move” to apply the changes.
  4. Click on the green checkmark at the top of the GParted window to apply the changes. This process might take some time, depending on the size of your partition.

Finalizing the Changes

After GParted finishes resizing your partition, you should reboot your system. Remove the Ubuntu Live CD/USB and boot into your installed Ubuntu system. Your root partition should now reflect the new size.

Conclusion

Resizing your root partition in Ubuntu is a straightforward process with the right tools. However, always remember to back up your data before resizing partitions to prevent data loss. With the Ubuntu Live CD/USB and GParted, you can easily adjust the size of your partitions to better suit your needs.
