Dual Booting Windows 11 and Ubuntu: The Developer‘s Guide

Dual booting enables developers to unlock the potential of both Windows and Linux without having to switch machines. By installing Ubuntu alongside Windows 11, you gain an efficient and flexible coding environment.

In this comprehensive 2600+ word guide, I‘ll cover all the steps for developers to configure a dual boot workstation – allowing you to harness the capabilities of each OS.

Why Developers Should Dual Boot

There are 5 key reasons dual booting shines for developers compared to using one operating system:

1. Native Linux Development – Tools like LAMP, Python, Ruby, etc integrate directly with Ubuntu‘s Linux kernel delivering much faster performance.

2. Bash Command Line – Linux terminals offer more customization, automation and work faster for developers than Windows cmd/PowerShell.

3. Open Source Ecosystem – Ubuntu provides thousands of FOSS tools for coding, collaboration, terminals, automation, containers and infrastructure.

4. Enhanced Security – Ubuntu is less vulnerable to malware/viruses allowing developers to securely code, experiment and test software.

5. Retain Windows Access – Dual booting permits developers to still use Visual Studio, MS SQL Server, Photoshop, games and other Windows-only apps.

According to Stack Overflow‘s 2022 survey, Linux usage amongst professional developers continues rising:

Desktop OS	2020	2021	2022
Linux	25.6%	29.2%	36.7%
Windows	50.7%	45.7%	43.5%

As developers embrace open source tools, dual booting Windows and Linux unlocks the perfect environment.

You gain the software accessibility only Windows provides paired with Linux‘s speed, security and terminal flexibility. Dual booting represents the best of both operating systems.

Dual Booting Prerequisites

Before getting started, verify your PC meets the following prerequisites:

• 64-bit Windows 11 version 21H2 or higher
• High speed internet for downloading Ubuntu
• Solid state or HDD with at least 50GB free space
• 16GB minimum RAM (32GB+ recommended)
• Backup stored securely on external media
• Supported EFI-mode UEFI BIOS version with Secure Boot
• USB flash drive for Ubuntu media (8GB+)

We will take advantage of Ubuntu‘s UEFI boot architecture using GPT partitioning instead of MBR. This requires a UEFI motherboard which has become the modern standard on recent PCs.

With Windows 11 already installed, you‘ll first shrink its main C drive partition to allocate free space for Ubuntu. This prevents data loss or conflicts by keeping the operating systems separated.

I strongly advise fully backing up your data and files in case issues emerge. Dual booting introduces added complexity, so precaution is key!

Downloading the Ubuntu ISO

To begin, download the latest Ubuntu 22.04 LTS desktop image ISO file from the official Ubuntu website:

https://ubuntu.com/download/desktop

I recommend the Long Term Support (LTS) version to maximize stability and support longevity for developers. New LTS builds land every 2 years with 5 years of product updates.

The 64-bit PC installer x86 build is ideal for most dual boot configurations. Ubuntu now even supports Windows 11 acceleration in the Linux kernel for full GPU utilization.

Once downloaded, verify the SHA256 hash matches Ubuntu‘s published value to guarantee integrity.

With the Ubuntu image ready, we‘ll prepare the bootable installer USB drive next.

Creating the Ubuntu Bootable USB

To installation media, you‘ll require:

• A USB flash drive with at least 8GB of storage
• [Rufus] reliable media creation tool that‘s free

Download and launch the latest version of [Rufus]. Insert your prepared USB drive while leaving all settings at default.

Under "Boot Selection", hit SELECT to browse your downloads for the .iso file, then click START. Rufus will fully format the drive before making it bootable with Ubuntu‘s installer.

Once finished, safely eject the USB drive containing Ubuntu. We‘ll later configure the boot priority to launch this before Windows 11.

Allocating Partition Space

The next phase involves splitting your storage to assign a section of the hard disk specifically for Ubuntu using the below steps:

1. Open Windows Search and launch "Create and format hard disk partitions"
2. Right click on your primary system drive visible under "Volumes"
3. Choose "Shrink Volume" to reclaim unused space into free storage

I recommend a partition size of at least 50GB for Ubuntu space. The more room allotted, the more flexibility for adding tools, apps and files within Linux.

Shrinking this volume can take some time. With ample free space now available, we can shift focus to UEFI firmware customization.

Configuring UEFI Settings

Unified Extensible Firmware Interface (UEFI) replaced legacy BIOS to support modern 64-bit architecture. We need to adjust some key settings under UEFI to allow booting Ubuntu from the USB drive.

First, reboot your PC and access UEFI through your vendor‘s provided hotkey method:

• ASUS: F2 or Delete keys
• Gigabyte: F12 or Delete keys
• MSI: Delete key
• Dell: F2 or F12 keys

Under the Boot tab, verify your drive mode is UEFI rather than "Legacy CSM". Change boot priority to rank your USB drive first temporarily.

To avoid conflicts between Ubuntu and Windows Secure Boot implementations, this feature should be disabled.

Finally, enable drives other than primary storage to act as bootable devices under the Security tab. Save settings and exit UEFI to apply these firmware changes.

Booting from the Ubuntu Media

With boot order now favoring the installer USB drive, turning on your PC will automatically launch Ubuntu for initial testing or permanent installation.

If instead Windows loads, tap the function key opening Boot Menu during POST to manually force boot device selection. Choose your inserted USB drive as the boot source.

Ubuntu‘s GRUB bootloader will display a welcome screen with "Try Ubuntu" or "Install Ubuntu" options. From here we can evaluate the desktop experience before committing changes.

Now we‘re ready to dual boot Ubuntu using guided partitioning in the installer!

Installing Ubuntu Alongside Windows

I‘ll break down the installation process covering some key options:

1. Language – Pick your locale, keyboard layout and primary language
2. Updates – Enable downloading updates during install to save time
3. Installation type – Choose "Install Ubuntu alongside Windows Boot Manager"
4. Erase disk – Decline this unless you want to remove Windows entirely
5. Time zone – Confirm settings are correct for your region
6. User details – Create your main administrator account

Ubuntu will automatically configure suitable partitions on the free space reserved earlier. You likely won‘t need to manually change suggested sizes or boundaries.

The installer will copy all necessary files, kernels and bootloaders essential for launch. Plan for roughly 10-15 minutes depending on your drive plus internet speeds.

Once finished, reboot removing any attached USB media. Before logging into Ubuntu, you should land at the GRUB menu.

GRUB Bootloader

GRUB stands for Grand Unified Bootloader, used for selecting between operating systems present. The menu displays Windows 11 and all Linux kernel entries:

GNU GRUB version 2.04

Ubuntu 
Advanced options for Ubuntu  
Windows Boot Manager (on /dev/sda1)
System setup

Use the arrow keys to pick an OS before hitting enter. The default changes to whatever you picked last.

By default, GRUB auto selects the first option after a 10 second countdown. This is configurable by installing Grub Customizer once logged into Ubuntu.

With GRUB functioning properly, congratulations – you now have a fully working Windows 11 and Ubuntu dual boot machine!

Post Installation Tips

I recommend a few next steps now that everything is up and running:

• Share files between OSs via a storage partition both can access
• Create system restore points and backups periodically
• Dual boot best practices: Always shut down, don‘t just force power off!
• Customize Ubuntu‘s appearance by switching Window Managers
• Install essential developer tools like git, Docker, Visual Studio Code, etc.

For example, the tiling i3 window manager helps maximize screen space compared to the default GNOME interface:

Tweaking your workflow through Linux customization unlocks added productivity as a developer.

Troubleshooting Help

Despite best efforts, you may encounter issues down the road with the dual boot configuration:

GRUB menu disappeared

If Windows boots directly, GRUB might be misconfigured or Ubuntu damaged. Use boot repair tools like Boot-Repair to reinstate GRUB detecting all operating systems.

Can‘t launch Ubuntu option

An update could have corrupted files preventing Ubuntu from loading properly via GRUB. Use older kernels from Advanced GRUB options to boot, then update packages.

Slow boot times

Too many unnecessary kernels installed over time can slow down POST and GRUB. Remove old Linux kernels no longer needed.

There are also fantastic communities like Ask Ubuntu and Ubuntu Forums for troubleshooting help.

Conclusion

Dual booting empower developers with Linux capabilities augmented by Windows compatibility into a frictionless coding environment.

Now you can develop natively against Linux tools while retaining access to unique Windows software. No more dual machines or virtualization overhead.

With Windows 11 and Ubuntu on a single workstation unified via GRUB, you reduce context switching and hardware costs. Resources once split are now pooled under the same hood.

To recap, dual booting warrants consideration for these main advantages:

• Consolidates Windows/Linux benefits into one desktop
• Boosts developer workflow via added customization
• Allows focus on building, not just managing systems
• Simplifies testing software against both OS types
• Provides fallback options preventing work stoppages
