Dual booting Windows 10 and Ubuntu allows you to have two operating systems on one computer. This means you can switch between Windows and Ubuntu whenever you want, giving you the best of both worlds. To do this, you’ll need to create a separate partition on your hard drive for Ubuntu, install Ubuntu on that partition, and then set up a boot manager to choose between the two systems when you start your computer. It’s a straightforward process, and with some patience, you can achieve a dual boot setup in just a few steps.
How to Dual Boot Windows 10 and Ubuntu
In this section, we’ll walk through the process of setting up a dual boot system with Windows 10 and Ubuntu. By the end of these steps, you’ll be able to switch between the two operating systems on one device.
Step 1: Back Up Important Files
Before you start, back up all your important files on an external drive or cloud storage.
This ensures that in case anything goes wrong during the installation, your data will remain safe and sound. It’s always better to be safe than sorry.
Step 2: Create a Partition for Ubuntu
Use the Disk Management tool in Windows to create a new partition for Ubuntu.
You’ll need to shrink your current Windows partition to make space for Ubuntu. Make sure to allocate at least 20GB for Ubuntu to ensure it runs smoothly.
Step 3: Download Ubuntu
Head to the official Ubuntu website and download the latest version of Ubuntu.
Choose the right version for your system architecture (32-bit or 64-bit). You’ll need a USB drive to create a bootable Ubuntu installer.
Step 4: Create a Bootable USB Drive
Use software like Rufus to create a bootable USB drive with the Ubuntu ISO file.
Insert the USB drive into your computer and use Rufus to write the Ubuntu ISO onto it. This will allow you to install Ubuntu from the USB drive.
Step 5: Boot from USB Drive
Restart your computer and boot from the USB drive to start the Ubuntu installation process.
You may need to change the boot order in the BIOS settings to prioritize USB booting. Once set, your computer will boot from the USB drive.
Step 6: Install Ubuntu
Follow the on-screen instructions to install Ubuntu on the new partition you created.
During the installation, choose the “Install Ubuntu alongside Windows 10” option. This will set up Ubuntu without affecting your Windows installation.
Step 7: Configure the Boot Manager
Once the installation is complete, configure the boot manager to choose between Windows and Ubuntu.
GRUB (GRand Unified Bootloader) will be automatically installed and will allow you to select which operating system to boot into each time your computer starts.
After completing these steps, your computer will be set up to dual boot Windows 10 and Ubuntu. Whenever you restart your computer, you’ll be greeted by the GRUB menu, allowing you to choose which operating system to use. This means you can enjoy the versatility of running both systems on a single machine.
