The procedure is not yet available for non-developers, as soon as the following guide is available it will be updated. To install Windows 11 on your device, you need to make sure Windows 11 is supported. To check compatibility, access the dedicated Microsoft page by clicking here . Furthermore, to complete the procedure you need a “separate” support (USB stick, Hard Disk or other) capable of “hosting” the files.Windows installation 11. The support device must be correctly connected to the PC. The procedure will completely format the memory on which Windows will be installed, clearing the memory itself before installation. Make sure you back up all important files on your PC before continuing with the installation from scratch. This procedure is not recommended if you are using multi-layered DVD or Bluray.

How to install Windows 11 from scratch

If you have a computer capable of supporting Windows 11, you must know that installing this operating system on your PC is child’s play and many times this operation solves many problems of incompatibility and slowness in a few minutes, bringing the device back to the “conditions” factory “. “Install an operating system from scratch” and “format a device” are synonymous.

For convenience we will divide the procedure into 2 phases: in the first phase we will explain how to create an installation media where to “insert” Windows 11 and it will be explained how to “start the PC by starting this installation”, in the second phase we will see the installation process step by step step to completion. And now let’s get started!

STEP 1: Create an installation media and select the correct BOOT

1) After checking the requirements of your PC, if you have a USB stick (or other media) containing the Windows 11 installation files, skip to step 4 . Otherwise, get a USB stick (or blank DVD).

2) Download the official application made available by Windows to prepare a USB stick for installing the operating system, or an installation DVD. The app is called “ MediaCreationTool “. I advise you to download the application only from the official Microsoft website, in order not to incur unpleasant surprises.

Click here to download MediaCreationTool for free from Microsoft’s official website (as soon as the tool is available, this page will be updated).

3) As soon as you open this application (it is not necessary to install it), you can decide whether to upgrade your PC to Windows 11, or whether to create a support to install Windows from scratch. Choose the item “Create installation media (USB flash drive, DVD or ISO file) for another PC” to perform a “clean” installation. The procedure will be completely guided , but make sure you have connected an empty USB stick of at least 32 or 64 GB to the PC . In this way you can create your USB stick containing Windows 11 (or alternatively a simple file in ISO format , for more experienced users) containing the installation of Windows 11, to use them as many times as you want .

Usually, for the preparation of the installation media, it is recommended to use a USB 3.0 or USB C stick, as they are faster in the installation process than a USB 2.0 stick.

4) Once your media has been created (you can create the installation USB stick from the same PC “to be formatted / reset” before starting “phase 2”) you can proceed with the installation of the Windows 11 operating system on the PC itself . To do this you will have to turn off the PC, then insert the media just prepared for installation (in case you have disconnected it), then restart the PC .

If you have done everything correctly, an “unusual” message will appear automatically, such as “Press a key to start Windows installation” (or something similar). All you have to do is press any key on the keyboard, wait for it to load and follow the installation wizard (described a few lines below, in the paragraph “PHASE 2”).

If your installation USB stick does not start automatically, you will have to “tell your motherboard” (your PC) to start first (compared to the other connected devices) the device you have prepared for installation (ie the USB stick itself). This is an unusual operation but don’t worry! To do this, simply access the UEFI or the BIOS (when the PC starts up, while the “written with logo” with the brand of your motherboard appears) and go to the BOOT section. Read on to better understand how to do it.

Each pc installed in its motherboard has a BIOS or UEFI (or similar) system which is used to manage, if necessary, the basic settings of the pc itself, including the BOOT settings. These settings are almost never needed (except when reinstalling an operating system from scratch and in a few other cases) and that is why this screen usually “appears” and then disappears quickly. To install Windows 11 from scratch you will need to access the settings on this screen and “tell the pc” that you intend to start the Windows 11 installation device first instead of starting a hard disk first (for example). If you don’t know how to access the BIOS or UEFI, click here or consult your motherboard manual.

A typical UEFI screen. In this case the system is UEFI BIOS Asus and from this system, through the main screen you can move and rearrange the BOOT devices directly in the “Boot Priority” window (right) with the help of the mouse pointer.

The typical “Boot” screen of a BIOS developed by American Megatrends.

Once in the UEFI BIOS general settings screen of your PC, from the “BOOT settings section” just look for the “Boot Priority” item also called “ Boot ” (or “ Boot Devices ” or similar names). Then , just set as “Primary driver” or ” Primary boot ” (or ” Primary drive ” or ” Primary device for boot ” or similar names) the device from which you intend to install the operating system (for example “UEFI USB KEY X” if you are installing from a USB key, or “DVD Player Brand X” if you intend to install from DVD). To do this, in modern configurations it will be enough for you(in many cases) drag the device (usually the USB stick or DVD you have prepared) as first in the list , that is, change the order from the menu and enter the USB or the installation device of the operating system you have prepared.

By setting your installation device as the “primary driver for booting” (for example, the USB stick you just prepared), you will “tell” the computer that that device must start up first when the PC is turned on compared to all other peripherals that may be connected . Only in this way, in fact, can the installation be started from scratch. As soon as you have perfectly installed your operating system (after point 12) of this guide), therefore, I recommend that you change the “primary driver” again, this time setting the memory unit in which you will have installed the operating system (SSD, Hard Disk, M.2 NVMe SSD etc.).

Save, restart your pc and proceed with the installation (STEP 2).

STEP 2: Install Windows 11 from scratch

5) Restarted the PC, to complete the installation procedure (if you have “pressed a button” to start the installation) you will have to wait for the “loading of the necessary screens” (usually takes a few seconds) to start the procedure. At this point, the Windows 11 installation program will start. Enter “Italian” , if not recognized automatically, in the fields present and click on “Next” .

6) Click on “Install” .

7) If you don’t have the Product Key, don’t worry. Select “I don’t have a product key” ; you will still be able to successfully install and use Windows 11, and then activate it later. Otherwise, enter the key to activate the Windows version and click on the “Next” button .

If you already have a genuine Windows license , clicking on “I don’t have a product key” will be the fastest option. In fact, starting with Windows 10 Insider Preview Build 14371 (a 2016 update of Windows 10) every Windows user license binds to the Microsoft account that uses it. So, to have a license you already own recognized, just log in with your Microsoft account at the first start (ie after completing all the operations in this guide) in order to “activate” Windows 11 with the Windows 10 license already purchased. You will find more details in the account area of ​​the normal Windows settings.

8) Choose the version of Windows 11 to install . You can choose between various versions such as Windows 11 Home or Windows 11 Pro, depending on the operating system license you have purchased. In case you entered the Product Key in the previous step, be careful to install the version you are licensed for. Click on “Next” .

9) Accept the license conditions by checking the relevant box and click on the “Next” button .

10) Now you will have to choose the type of installation to perform. Choose “Custom: Install Windows only (advanced option)” .

11) In this step you will select the partition on which to install Windows 11. Usually there will be only one partition but in case of doubt I suggest you delete them all by clicking on “Delete” until there is only one “Unallocated drive” to select. Select the partition where you are going to install Windows and click on “Next” .

By eliminating all the “additional” scores, your memory (SSD, Hard Disk etc.), usually called “C:”, will be “formatted” without being “fragmented into blocks” and you can then use all the space available in it. Also, be sure to select the correct drive to actually install the operating system. If you have too many hard drives connected to the PC and in this screen you get confused, I suggest you turn off the PC and disconnect them all, and then reconnect only the memory unit where you want to install Windows and turn the PC back on in order to relaunch the procedure. installation from scratch.

12) Very well, the process is coming to an end. At this point, the automatic installation of Windows 11 will begin. Wait for it to complete. Once the installation process is finished, you will only have to start Windows for the first time by following the guided wizard.

In the last phase you can then configure various options for privacy and geolocation and even connect to the internet and log in with your Microsoft account. I advise you, in these phases, to carefully evaluate the permissions that you will “grant” to the new operating system, but you will still have full freedom of choice.

Once you have followed the wizard step by step (the procedure is guided and even if it is very intuitive, it varies depending on the version of Windows 11) for the first start of Windows 11 (these configurations will be carried out only at the first start!), The procedure will be finished. Now you can finally enjoy the new Windows 11 on your pc! Simple, isn’t it?
