Clean Install Windows 11

This tutorial will show you step by step on how to clean install Windows 11 at boot on your PC with or without an Internet connection and setup with a local account or Microsoft account.

Windows 11 has all the power and security of Windows 10 with a redesigned and refreshed look. It also comes with new tools, sounds, and apps. Every detail has been considered. All of it comes together to bring you a refreshing experience on your PC.

A clean install of Windows 11 will wipe out everything on the drive you select to install Windows 11 on giving you a completely new default installation of Windows 11.

Starting with Windows 11 build 25905, Microsoft have adjusted the prerequisites (removal of Modern Standby/HSTI validation and untrusted DMA ports check) for enabling device encryption so that it is automatically enabled when doing clean installs of Windows 11.

It is required to be connected to the Internet if you want to set up a Microsoft account during Windows Setup.

It is not required to be connected to the Internet if you want to set up a local account during Windows Setup.

If you set up a Microsoft account during Windows Setup, it will get linked to OneDrive to backup and sync your files by default. You can either set up a local account instead to avoid this, or stop the backup and sync your files to OneDrive when the installation is complete.

If you set up a Microsoft account during Windows Setup, your user profile folder in the "C:\Users" folder will be named with the first 5 characters of the email address used for your Microsoft account. If you want to specify the name of your user profile folder in the "C:\Users" folder, then you will need to set up a local account during Windows Setup instead of a Microsoft account so your user profile folder will have the same name you enter as the local account name. When Windows 11 has finished installing, you can switch to a Microsoft account from the local account (if wanted) without the user profile folder name getting changed.

Here's How:

1 If you have not already, you will need to create a bootable Windows 11 installation USB with UEFI support.

2 It is recommended to temporarily disconnect or disable all non OS hard drives until Windows installation has finished for the following reasons:

To avoid you mistakenly deleting or formatting the wrong disk or drive.
To prevent Windows Setup from installing the boot configuration files (bootloader) to a different connected hard drive instead of on the disk Windows will be installed on.

3 Boot to the UEFI firmware settings for your motherboard, and enable UEFI or disable Legacy BIOS (CSM) mode.

Usually it will already be set to UEFI mode by default unless you have an old system. You may need to read your PC's or motherboard's manual for its specific instructions on how to change this setting.

4 Boot from the Windows 11 installation USB flash drive on your computer.

5 Perform the following steps to select your language and keyboard settings: (see screenshots below)

Select your Language to install.
Select your Time and currency format.
Click/tap on Next.
Select your Keyboard or input method.
Click/tap on Next.

6 Select (dot) Install Windows 11, check I agree everything will be deleted including files, apps, an settings, and click/tap on Next.

7 Enter your Windows 11 product key, and click/tap on Next. (see screenshot below)

The product key you enter will determine which edition of Windows 11 gets installed, and is required to activate Windows 11 unless you activate with a digital license instead. If you don't enter a product key and click/tap on I don't have a product key, you will be able to select the Windows 11 edition you want to install at step 8 below, but Windows 11 will not be activated.

You can enter an official ~~Windows 7~~, ~~Windows 8.1~~, or Windows 10 retail product key (OEM keys will not work) not currently used to activate Windows on another PC, and click/tap on Next to activate Windows 11.

Free Activation from Windows 7/8 key or upgrade to Windows 10/11 Ends

If you do not have a product key available right now, click/tap on the I don't have a product key link, select the Windows 11 edition you want to install at step 8. You will be able to manually activate Windows 11 with your product key when you want later after the Windows 11 installation has finished.

If you want to activate with a digital license linked to your Microsoft account, click/tap on the I don't have a product key link, select the Windows 11 edition you want to install at step 8, and add your linked Microsoft account at step 20 .

You will not be asked to enter a product key if installing Windows 11 Enterprise. You will need to manually activate later after installation has finished.

If this is an OEM PC that has a valid product key embedded in its UEFI firmware chip, then you will not be prompted to enter a product key. Windows 11 will automatically use the embedded product key if its valid for the edition being installed. If needed, you can change the product key after installation has finished.

8 If you clicked on I don't have a product key in step 7 above, then select the Windows 11 edition you want to install, and click/tap on Next. (see screenshot below)

9 Click/tap on Accept for applicable notices and license terms. (see screenshot below)

10 Perform one of the following actions to select a drive or disk to install Windows 11 on: (see screenshots below)

Default UEFI/GPT Hard Drive Partition Layout Description for Windows 10 and 11

This tutorial will explain each partition of the default partition layout created when you clean install Windows 10 or Windows 11 on a blank hard disk drive (HDD) or solid-state drives (SSD). When you clean install Windows 10/11 to a blank unallocated disk with UEFI, the disk is formatted using...

If RAID is enabled in UEFI/BIOS, Windows Setup may not see any drive(s) available to select to install on.

In this situation, you could either disable RAID in BIOS/UEFI or select to "Add driver" to install the RAID driver from your OEM/motherboard manufacturer's chipset.

Starting with Windows 11 build 26200.5516 (Dev) and build 26120.3653 (Beta), Microsoft is removing the bypassnro.cmd script from the build to enhance security and user experience of Windows 11. This change ensures that all users exit setup with internet connectivity and a Microsoft Account.
