How to Dual Boot Ubuntu on Windows 10

Dual booting Ubuntu on Windows 10 means running two operating systems on the same computer. First, you’ll need to create space on your hard drive to install Ubuntu.

This setup will allow you to choose which OS to use every time you start your computer.

Dual Boot Ubuntu on Windows 10

Ready to explore the world of Linux? Here’s a step-by-step guide to get you dual booting Ubuntu on Windows 10. You’ll create a harmonious tech blend right at home!

Step 1: Back Up Your Data

Before starting, ensure you back up all important files.

Having a backup will protect your data in case anything goes sideways during the installation process. Use an external drive or cloud storage.

Step 2: Create Space on Your Hard Drive

Shrink your Windows partition to make space for Ubuntu.

Head to Disk Management in Windows, right-click the partition you want to shrink, and choose how much space to free up. Be sure you have at least 20GB available for Ubuntu.

Step 3: Download Ubuntu

Go to the Ubuntu website and download the latest ISO file.

Choose a version of Ubuntu that suits your needs, whether it’s the latest release or a long-term support version.

Step 4: Create a Bootable USB Drive

Use software like Rufus to create a bootable USB from the Ubuntu ISO.

Insert a USB drive with at least 4GB capacity. Rufus will format it, so ensure nothing important is stored there.

Step 5: Restart and Boot from USB

Restart your computer and boot from the USB drive.

Access your computer’s boot menu (usually by pressing F12 or ESC) and select the USB drive to start the Ubuntu installation process.

Step 6: Install Ubuntu Alongside Windows

Select “Install Ubuntu alongside Windows Boot Manager.”

Follow the on-screen instructions to partition the available space for Ubuntu, set your time zone, and create a user account.

After completing these steps, Ubuntu will be installed on your system. On startup, you’ll see a menu allowing you to choose between Windows 10 and Ubuntu.
