Ready to get started? Let’s dive in!

How to Dual Boot Ubuntu and Windows 11

In this section, we’ll walk through setting up a dual boot system with Ubuntu and Windows 11. This means you’ll install Ubuntu on the same computer that already has Windows 11, and you can choose which one to use each time you turn on your computer.

Step 1: Back Up Your Data

Make sure you have backups of your important files before starting.

Before making any changes, always play it safe by copying important documents, photos, and other files to an external hard drive or cloud storage. This way, you won’t lose anything important if something goes wrong.

Step 2: Create Space on Your Hard Drive

Shrink your Windows partition to create unallocated space for Ubuntu.

Open Disk Management in Windows 11 by typing “Disk Management” in the search bar. Right-click on the Windows partition (usually C:), select “Shrink Volume,” and allocate enough space for Ubuntu (at least 20 GB).

Step 3: Create a Bootable USB Drive

Download Ubuntu and create a bootable USB drive using a tool like Rufus.

Head to the Ubuntu website and download the latest version. Then, use Rufus (or a similar program) to make a bootable USB drive by following the on-screen instructions.

Step 4: Boot From the USB Drive

Restart your computer and boot from the USB drive to start the Ubuntu installation.

Insert the USB drive and restart your PC. Enter the BIOS/UEFI settings (usually by pressing F2, F12, Delete, or Esc) and set your computer to boot from the USB drive.

Step 5: Install Ubuntu

Choose “Install Ubuntu” and follow the prompts to install it alongside Windows 11.

Once in the Ubuntu installation menu, select “Install Ubuntu.” When prompted, choose the option to install Ubuntu alongside Windows Boot Manager. Follow the installation prompts to complete the process.

After completing these steps, your computer will restart, and you’ll see a menu (GRUB) that lets you choose between Ubuntu and Windows 11 every time you turn on your computer.

Tips for Dual Booting Ubuntu and Windows 11

  • Keep Your System Updated: Regularly update both Ubuntu and Windows 11 to ensure they run smoothly.

  • Use EasyBCD for Boot Issues: If you encounter boot issues, tools like EasyBCD can help manage boot configurations.
