Adjusting Ubuntu Partition Size in Dual-Boot Setup

Ubuntu 13

In a dual-boot setup, you may find yourself needing to adjust the partition size of your Ubuntu system. This could be due to a variety of reasons, such as needing more space for your Windows system, or wanting to allocate more space to Ubuntu. In this article, we will guide you through the process of adjusting the partition size for Ubuntu in a dual-boot setup using a utility called GParted.

Quick Answer

To adjust the partition size of Ubuntu in a dual-boot setup, you can use a utility called GParted. This involves booting from an Ubuntu Live CD or USB, installing GParted, and using it to resize and move the partitions as needed. Be sure to back up your data before making any changes, as it can potentially lead to data loss.

Preparing for the Process

Before we start, it’s important to note that adjusting partition sizes can potentially lead to data loss. Therefore, it’s crucial to back up any important data before proceeding.

In addition, you’ll need an Ubuntu Live CD or USB to perform the process. This is because you cannot resize a partition that is currently in use, so you’ll need to boot from a different source.

Installing GParted

GParted is a free partition editor that allows you to resize, move, and manage your disk partitions. It is not installed by default on Ubuntu, but you can easily install it once you boot up from the Ubuntu Live CD or USB.

To boot from the Ubuntu Live CD or USB, restart your computer and select the appropriate boot option. Once you’re in the live environment, choose “Try Ubuntu”.

Next, open a terminal by pressing Ctrl+Alt+T. In the terminal, run the following command to install GParted:

sudo apt-get install gparted

The sudo command allows you to run commands with administrative privileges, while apt-get install is the command to install new software on Ubuntu.

Using GParted to Resize Partitions

Once GParted is installed, you can launch it by running the following command in the terminal:

sudo -i gparted

The -i option stands for “interactive”, which means that GParted will run in a mode where it waits for user input.

In GParted, select your internal hard disk from the drop-down menu at the top right. Be sure to choose the correct disk to avoid any data loss.

Next, identify your Ubuntu and Windows partitions. The Ubuntu partition will typically be of type ext4 and may have a mount point of /, while the Windows partition will be of type ntfs.

Right-click on the Ubuntu partition and select “Resize/Move”. Adjust the size to the desired value, making sure to leave enough space for your applications and data.

After resizing the Ubuntu partition, you’ll see some unallocated space. Move this space so that it is after the Windows partition.

Next, right-click on the Windows partition and select “Resize/Move”. Expand it to take over the unallocated space.

Once you’re satisfied with the new partition layout, apply the changes by clicking the check mark in GParted.

Final Steps

After you’ve finished resizing the partitions, reboot your system and remove the Live CD or USB. Your system should boot up normally, and you should see the new partition sizes reflected in your system.

Remember, resizing and moving partitions can take a long time, depending on the size of the partitions and the amount of data being moved. Be patient and let the process complete.

If you encounter any issues during the process, consult the GParted documentation for troubleshooting steps.

In conclusion, adjusting the partition size of Ubuntu in a dual-boot setup is a straightforward process with the right tools. By following the steps in this guide, you can easily allocate more or less space to your Ubuntu system as needed. Always remember to back up your data before making any changes to your partitions, and don’t hesitate to seek help if you encounter any issues.
