How To Allocate More Hard Disk Space to Ubuntu in Dual-Boot with Windows 10

Ubuntu 3

In this article, we will discuss how to allocate more hard disk space to Ubuntu in a dual-boot setup with Windows 10. This process involves resizing your Windows partition to create unallocated space and then extending your Ubuntu partition to utilize this space. Before proceeding, it’s highly recommended to backup your data to avoid any potential data loss.

Quick Answer

To allocate more hard disk space to Ubuntu in a dual-boot setup with Windows 10, you need to shrink your Windows partition to create unallocated space and then resize your Ubuntu partition to utilize this space. This can be done using tools like Disk Management in Windows and GParted in Ubuntu. Remember to backup your data before making any changes to your disk partitions.

Prerequisites

Before we begin, you need to have a live USB of Ubuntu. If you don’t have one, you can create it using tools like Rufus or UNetbootin. You’ll also need to ensure that GParted, a free partition editor for graphically managing your disk partitions, is installed on your live USB. If it’s not, you can install it using the Ubuntu Software Center, Synaptic Package Manager, or by running the following command in a terminal window:

sudo apt-get install gparted

Shrinking the Windows Partition

The first step is to shrink your Windows partition to create unallocated space. Follow these steps:

  1. Boot into your Windows 10 system.
  2. Press Win + X and choose Disk Management.
  3. Find the main Windows partition (usually C: drive) and right-click on it, then select Shrink Volume.
  4. Enter the amount of space to shrink in MB and click on the Shrink button.

The unallocated space will appear as a black bar in the Disk Management window.

Resizing the Ubuntu Partition

Now, we’ll boot into Ubuntu using the live USB and resize the Ubuntu partition.

  1. Restart your system and boot from the live USB.
  2. Open GParted. If you’re not sure how to do this, you can search for it in the Dash or run the following command in a terminal window:
sudo gparted
  1. In GParted, locate your Ubuntu partition. It should be labeled as “ext4” in the file system column.
  2. Right-click on the Ubuntu partition and select Resize/Move.
  3. In the resize dialog, adjust the partition size to include the unallocated space. You can either enter the desired size manually or drag the partition boundary.

The Resize/Move dialog shows the partition size in MiB. You can adjust the New size field to increase or decrease the partition size. The Free space following field shows the unallocated space. Ensure that this value is 0 after you’ve adjusted the partition size.

  1. Click on the Resize/Move button to apply the changes.
  2. Finally, click on the green checkmark button to start the resizing process.

Once the process is complete, reboot your system. Your Ubuntu partition should now have more disk space.
