Introductory

In this dual boot description, we first install a Windows 11 operating system and then an instance of Ubuntu 21.10 (Impish Indri) Linux. The installation is a 64-bit UEFI based machine, where a GUID with partition table (GPT) 64-bit systems will also be mounted on two partitions of a built-in hard disk.

This combination includes the latest releases for both Windows and Ubuntu, so creating this dual boot assembly is a lifeline, which can be used for everyday use in addition to studying and getting to know each other.

Prerequisites

Before starting the installation, you should consider examining the influencing factors and conditions to make sure this is the right setup for us. Because this applies to all parts of the dual-boot / multi-boot description series, this is the subject of the Multi-boot systems category page I collected the most important theoretical parts.

hardware environment

This installation VirtualBoxI finish in which I set up like this (4 CPU cores, 8GB RAM, 80GB hard drive). This configuration is sufficient for both operating systems, but let's review the manufacturers' recommendations to make sure your computer meets the following system requirements:

Windows 11

• CPU: 1 GHz or faster, at least 2-core, 64-bit processor
• RAM: At least 4GB
• HDD: At least 64 GB of storage
• Motherboard system: UEFI+secure boot +TPM
• Video:  DirectX 12-compatible or later with WDDM 2.0 driver.

More details can be found here.

Ubuntu 21.10 (Impish Indri) Linux

• CPU: 2 GHz or faster, at least 2-core, 64-bit processor
• RAM: At least 4GB
• HDD: At least 25 GB of storage
• Video: At least 256MB of video memory, card with 3D acceleration capabilities

Get Windwos 11 and build a bootable device

Windows 11 was released on October 2021, 4, and is currently (March 2022) the latest release of Windows from Microsoft. The Operating System Home, Pro, For Education and the Pro for Workstations versions will receive software support until October 2023, 10, while Enterprise, Educations, IoT Enterprise versions will receive updates by October 2024, 8. Source.

If you already have Windows 11 on which you want to install Ubuntu 21.10 (Impish Indri) as a secondary, you can skip this section of Windows 11 and configure the partitions during Ubuntu installation. If, on the other hand, you don't have anything on your computer yet, of course, let's start by installing Windows 11.

After the ISO file has finished downloading, make it a bootable device. Keep in mind that the ISO installation image must be written to your flash drive in UEFI mode.

When you are done, start your computer with the installation tool you have created.

Installing Windows 11

Once the installer has started, you can start setting up.

Regional settings

In the first window you can make regional settings:

Here you can set the language, time and currency format that is right for you, as well as the keyboard language. Then click on More button.

Start installation

You can start a fresh installation here, or you can repair a previous damaged copy of Windows by clicking the link at the bottom left. Click the middle Installation button.

Activating Windows

The next step is to activate Windows:

If you have a product key, enter it here. For the sake of demonstrating a dual-boot installation, it doesn't matter if Windows is activated now, so I'll move on with the "I don't have a product key" option below.

Select system type

Next, we need to select the type of system we want to install:

Select the version of the product that corresponds to our license here. I am now installing the Education version here.

If you are installing in VirtualBox, clicking Next will launch an error window stating "This computer is not compatible with Windows 11"

So here we will continue with the installation after resolving the issue. If you do not receive this error message, it means that your computer is running Windows 11 or has already been fixed for VirtualBox.

Accept License Terms

Next, we need to accept the license terms:

Check the checkbox below and then click next.

Select the installation method

In this step, you need to choose whether you want to perform a simpler update or customize the installation yourself with more detailed configuration options:

Select the bottom detailed installation method here.

Hard Disk Partitioning

For dual-boot installations, this is an important step that we need to perform judiciously. So here we need to allocate the storage in the machine so that there is enough space for both operating systems. If no partition has been created on the hard disk, this status will be accepted in the first place:

There is a good chance that everyone will have a different scenario, so here we have to consider how to partition our existing hard drive (s). It is also possible that someone wants to install the two operating systems on two hard disks separately. Here we are now going through the current lineup, so there is a piece of 80GB hard drive that will be split into multiple partitions with a GPT partitioning scheme. So here you need to create enough space for both systems to fit. 11GB of storage is recommended for Windows 64 and 25GB for Ubuntu. It doesn't fit the 80GB size, so we're going to farm a little less space in this example.

Once you have decided on the size of the first partition to be created for Windows 11, click on the "new" option. An input field will appear below the list of partitions where you can specify the size of the partition to be created in MB. By default, it offers us the full size setting, which is 80 "MB" for the 81920GB HDD. So here I set up 61440 MB (60 * 1024) to come out to exactly 60 GB:

Then click "Apply".

Here's how the installer can create additional partitions:

Click OK here.

This will create a new partition on my back:

So here the system created a 100MB system partition, a 16MB MSR partition and a 59,9GB primary partition. The first two of these system partitions are required to boot UEFI, while the third large partition is the Windows installation partition. In addition, there is 20GB of free space left, which we will not touch on now, but will use it when installing Ubuntu.

If you are still there and the selection is on the correct partition (the third large partition), click More button.

Installing Windows

Then the installer starts, which we have to wait for:

After you go through it, restart your computer:

It still spins here, works for a while, of course depending on the performance of the machine, and then comes the settings ...

Region setting

First we need to set up our region:

If you set the right one by default, click Yes button.

Select a keyboard layout

Then select the keyboard layout:

Here you can choose from a long list, where the "Hungarian" allocation is the first. That will be good. Click on Yes button.

You can even add a second keyboard layout here:

If you do not want a secondary keyboard layout, click Omission button.

Check for updates

In this step, Windows will check for updates:

We have nothing to do here, we just wait for it to finish.

Then restart your computer again:

Login

In this step, you need to enter your login information:

By default, you are offered a Microsoft account. If you have a Microsoft account, give it access here. Because I'm getting a stroke from this Microsoft account and the whole cloud, I'm creating a local user. Previously, Windows 10 required this to be installed without an Internet connection, and fortunately there is a workaround to use your computer with a local user. To do so, click on the "Login Settings" link below the email address input field:

Here you have two options: Log in with a security key and Join Domain. Choose the second of these:

You can now enter a local username. Enter it and move on.

You will then be prompted for the password:

Enter a password here, or leave it blank. Then let's move on.

Requests for permission

After logging in, there are already known permission request windows from Windows 10, let's decide according to our discretion and needs.

In the meantime, the activation watermark has already appeared in the lower right corner, but this does not interfere with the installation. I paused here for a few hours during the installation, so this message has now appeared.

Use of location

Device tracking

Send diagnostic information to Microsoft

Improving freehand operations and typing

Use of diagnostic data

Enable the use of an ad ID

Check for updates

After the permission request panels, the system checks for updates again:

Preparation

The installer will then prepare the system for booting:

Windows 11 is ready to use

Finally, Windows starts, the desktop loads, and the Start menu window appears by default:

Closing the window, the table is empty:

And finally, another engine room window:

and the classic control panel, where you can configure everything in more detail:

After installation, and after shutting down the machine, the physical size of the virtual disk image file is fattened to 10,61GB, so it is still well below 60GB.

So we've installed Windows 11, next page and we will continue our dual boot installation by installing the second operating system, Ubuntu 21.10 (Impish Indri) Linux on another partition.
