Stop Choosing! Run Windows 11 and Ubuntu Together with This Easy Guide

For many tech enthusiasts, the debate between Windows and Linux is never ending. Windows 11 offers a polished interface and unparalleled gaming support, while Ubuntu Linux provides a robust environment for programming, privacy, and customization. Why settle for just one when you can have the best of both worlds on a single machine?

Setting up a dual boot system might seem intimidating if you have never touched a BIOS screen before. However, modern installers have made the process much smoother. This guide to dual boot Windows 11 and Linux Ubuntu will walk you through the entire journey, from preparing your hardware to navigating the final boot menu.

Why Consider a Dual Boot Setup?

According to a report by The Verge, while Windows remains the dominant desktop operating system, Linux distributions like Ubuntu are seeing increased adoption among software engineers and data scientists. Having both operating systems allows you to switch contexts instantly. You can use Windows for Adobe Creative Cloud or AAA gaming, then reboot into Ubuntu to manage servers or write code in a distraction free environment.

Before we dive into the technicalities, it is important to understand that Windows 11 has specific hardware requirements, such as TPM 2.0 and Secure Boot. Fortunately, modern versions of Ubuntu are fully compatible with these security features, making the coexistence of these two giants easier than ever.

Essential Prerequisites and Tools

Before you start clicking through installation menus, you need to gather a few items. Preparation is the key to avoiding a “blue screen of death” or a lost partition.

• A High Speed USB Drive: You need a flash drive with at least 8 GB of space. This will serve as your installation media.

• The Ubuntu ISO Image: Always download the latest Long Term Support (LTS) version from the official Ubuntu website. LTS versions offer five years of guaranteed updates.

• Rufus: This is a small, free utility used to create bootable USB drives.

• Sufficient Disk Space: You should have at least 50 GB of free space on your hard drive or SSD, though 100 GB is recommended for a better experience.

Based on a guide by TechCrunch, backing up your data is the most critical step before performing any system level modification. While dual booting is generally safe, a power outage or a wrong click during partitioning could result in data loss. Always back up your important documents to the cloud or an external drive first.

Preparing Windows 11 for Ubuntu

Windows 11 likes to “own” the entire hard drive. To make room for Ubuntu, you must manually shrink your existing C: drive. This creates unallocated space where the Linux filesystem can live.

1. Open Disk Management: Right click the Start button and select Disk Management.

2. Shrink Volume: Locate your primary partition (usually C:). Right click it and choose “Shrink Volume.”

3. Define Space: Enter the amount of space you want to give to Ubuntu in megabytes. For example, 51200 MB equals 50 GB.

4. Leave it Unallocated: After the process, you will see a black bar representing “Unallocated” space. Do not format this space yet; Ubuntu will handle that.

Additionally, you must disable “Fast Startup” in Windows. This feature puts the filesystem in a semi-hibernated state, which prevents Linux from accessing it. You can find this setting under Control Panel > Power Options > Choose what the power buttons do.

Creating the Bootable USB Drive

Now that your drive is ready, you need to turn your USB flash drive into an installer.

1. Plug in your USB drive and launch Rufus.

2. Select your USB drive under the “Device” section.

3. Click “Select” and find the Ubuntu ISO file you downloaded earlier.

4. Ensure the Partition Scheme is set to GPT and the Target System is UEFI (non CSM). This is crucial because Windows 11 only runs on UEFI.

5. Click “Start” and wait for the process to finish.

Navigating the BIOS and Secure Boot

To boot from your USB, you need to interrupt the standard Windows startup. This is often done by tapping a specific key like F2, F12, Del, or Esc right after pressing the power button.

According to PCWorld, hardware manufacturers have different keys for BIOS access. For example, Dell usually uses F12, while HP often uses F10. Once inside the BIOS:

• Disable Fast Boot: This is different from the Windows setting and is found within the BIOS menus.

• Secure Boot: In the past, users had to disable Secure Boot to install Linux. However, Ubuntu now supports it. If you encounter issues, you might need to disable it temporarily, but try keeping it enabled first.

• Boot Order: Move your USB drive to the top of the boot priority list.

The Ubuntu Installation Process

Save your BIOS settings and restart. Your PC should now load the Ubuntu “Grub” menu. Select “Try or Install Ubuntu.”

Once the desktop loads, click the “Install Ubuntu” icon. Follow the prompts for language and keyboard layout. When you reach the “Installation Type” screen, you have two main options:

Option A: Install Alongside Windows Boot Manager

This is the safest and easiest method for beginners. The installer detects Windows 11 and offers to use the unallocated space automatically.

Option B: Something Else (Manual Partitioning)

This is for advanced users who want to create separate partitions for “Root,” “Home,” and “Swap.” If you chose the “Something Else” option, ensure you select the unallocated space you created earlier and format it as an Ext4 journaling file system.

Comparison of Windows 11 and Ubuntu Linux

Post Installation and the Boot Menu

Once the installation is complete, the system will ask you to remove the USB drive and restart. Upon rebooting, you should be greeted by the GRUB bootloader. This is a simple black screen that lets you choose between booting into Ubuntu or the Windows Boot Manager.

If your computer boots straight into Windows, do not panic. This usually means Windows set itself as the primary boot manager again. You can fix this by going back into your BIOS settings and ensuring “ubuntu” is ranked higher than “Windows Boot Manager” in the boot priority list.

Frequently Asked Questions

Will dual booting slow down my computer?

No. Only one operating system runs at a time. The only thing you lose is disk space because it is divided between the two systems.

Can I access my Windows files from Ubuntu?

Yes, Ubuntu can natively read and write to Windows NTFS partitions. However, Windows cannot read Linux Ext4 partitions without special third party software.

Is it easy to remove Ubuntu later?

Yes, you can delete the Linux partitions from Windows Disk Management and then use a tool like “EasyBCD” or Windows recovery to fix the bootloader.

Does dual booting void my warranty?

In most cases, no. Software modifications do not usually affect hardware warranties, but it is always wise to check with your manufacturer if you have a high end laptop.

Final Thoughts
