How to Create a Windows 11 Bootable USB with Rufus and Perform a Clean Install
Installing Windows 11 from a properly prepared USB drive can be useful when you want a clean operating system, need to reinstall Windows after a serious software problem, or want to start over with a fresh system.
The original script refers to the tool as “RFOS,” but the correct application is Rufus, a popular utility for creating bootable USB installation media. Rufus 4.15 is the latest release shown by the official project repository as of June 30, 2026.
This guide explains the complete workflow, including downloading the official Windows 11 ISO, creating the bootable USB with Rufus, understanding the available customization options, performing a clean installation, creating a local account where supported, and removing unnecessary Windows components after setup.
Windows 11 officially requires a compatible 64-bit processor, at least 4 GB RAM, 64 GB storage, UEFI firmware with Secure Boot capability, TPM 2.0, and compatible graphics hardware. Microsoft recommends installing Windows 11 on supported hardware, so bypass options should not be treated as equivalent to meeting the official requirements.
What You Need Before Starting
Before creating the installation media, prepare the following:
A working Windows PC.
A reliable USB flash drive with sufficient capacity for the Windows 11 installation media.
A stable internet connection for downloading the ISO and Rufus.
The official Windows 11 ISO from Microsoft.
Rufus downloaded from its official website or official project repository.
A backup of important personal files.
The USB drive will normally be erased while creating the bootable media, and the target drive can also be completely erased during a clean installation. Microsoft explicitly warns that content on the installation media can be deleted, so backing up important files first is essential.
Download the Official Windows 11 ISO
Open Microsoft's Windows 11 Download Page
Start by opening the official Microsoft Windows 11 download page.
Look for the section for downloading the Windows 11 Disk Image (ISO). Microsoft provides a multi-edition ISO for x64 devices, which can be used to create bootable installation media.
Avoid downloading Windows ISO files from unknown third-party websites. Using the official Microsoft source is a safer way to ensure that you are working with genuine installation media.
Select the Windows 11 Edition and Language
Choose the available Windows 11 ISO option and select the requested product language.
The downloaded ISO is a multi-edition image. The appropriate Windows edition is normally selected during installation based on the available license or product key.
Download the 64-bit ISO
For a normal modern Intel or AMD desktop or laptop, download the x64 ISO.
The download can be several gigabytes in size, so the exact time depends on your internet connection and Microsoft's current ISO package size.
After downloading, confirm that the ISO file is stored somewhere easy to locate, such as the Downloads folder.
Download Rufus for the Bootable USB
Get Rufus from the Official Project
Open the official Rufus website or the official Rufus GitHub repository and download the current release.
The official project identifies Rufus as a utility for creating bootable USB drives, and the project repository currently lists Rufus 4.15 as its latest release.
Rufus is also available as a portable application, so installation is not necessarily required.
Start Rufus
Connect the USB flash drive to the Windows PC and open Rufus.
If Windows shows more than one removable storage device, carefully identify the correct USB drive before continuing. Selecting the wrong drive can result in accidental data loss.
This is one of the most important practical checks in the entire process.
Create the Windows 11 Bootable USB
Select the Correct USB Device
In Rufus, look at the Device field and make sure the intended USB flash drive is selected.
If the expected USB device does not appear, reconnect it and verify that Windows itself can detect the drive.
Do not continue until you are certain that the correct device is selected.
Select the Windows 11 ISO
Under Boot selection, choose the option to use an ISO image and then browse to the Windows 11 ISO you downloaded from Microsoft.
Select the ISO and allow Rufus to analyze the image.
Depending on the ISO and Rufus version, additional configuration options may appear. Rufus has received multiple changes across recent releases, so the wording and exact appearance of some dialogs can differ between versions.
Configure the USB Name and Partition Settings
You can give the USB drive a recognizable volume label such as Windows 11.
For a modern computer using UEFI, GPT is generally the appropriate partition scheme. Older systems may use different firmware configurations, so choosing the correct mode for the target computer is important.
A mismatch between the boot mode and partition scheme can prevent the computer from booting from the USB.
Understand Rufus Windows 11 Customization Options
TPM and Secure Boot Restrictions
Depending on the Windows ISO and Rufus version, Rufus may present Windows User Experience options that can modify how the Windows installer handles certain requirements.
These options can include bypassing specific Windows 11 hardware checks such as TPM or Secure Boot requirements.
This is important: bypassing an installation check does not make unsupported hardware officially supported by Microsoft. Microsoft's official requirements still include TPM 2.0 and UEFI/Secure Boot capability.
Rufus itself explains that its Windows installation bypass mechanisms rely on facilities provided by Microsoft rather than modifying or reverse-engineering Windows binaries.
Microsoft Account and Local Account Options
Some Rufus versions and Windows ISO combinations provide options intended to make local-account setup easier during Windows installation.
Rufus documents that its local-account behavior can depend on the Windows version and network state. In particular, the Windows installer may use the Microsoft online account flow when internet connectivity is available.
Because Microsoft continues changing the Windows setup experience, the exact account options should not be assumed to work identically on every Windows 11 release.
Disable Unnecessary Data Collection Options Carefully
Some Rufus configuration screens may provide additional Windows User Experience options related to privacy, automatic setup behavior, or account creation.
Only select options you fully understand.
A clean installation should remain predictable and maintainable. Removing or disabling something simply because it sounds unnecessary can occasionally affect features that you later expect to use.
Avoid Experimental or Specialised Options Unless Needed
Rufus may display additional Windows installation options that are designed for specific hardware, security, or compatibility scenarios.
For a normal clean Windows 11 installation, unnecessary experimental settings should be left at their defaults.
This reduces the chance of creating installation media that behaves differently from what you intended.
Start Creating the Bootable USB
After reviewing the options, start the Rufus process.
A warning will normally appear because the selected USB drive will be formatted. Confirm only after verifying the correct device.
Rufus will then write the Windows 11 installation files to the USB drive and make the device bootable.
The duration depends on the USB drive, computer, and ISO image. Do not remove the USB drive while the writing process is still running.
When Rufus reports that the process is complete, safely close the application.
Prepare the Computer for a Clean Windows 11 Installation
Back Up Important Data First
A clean installation is fundamentally different from an in-place upgrade.
A clean install can remove applications, settings, and personal data from the selected partitions. Make sure important documents, photos, browser data, license information, and other files are backed up to a separate drive or trusted cloud storage.
Check UEFI, TPM, and Secure Boot Status
Before relying on bypass options, check whether your computer actually supports Windows 11 requirements.
Modern systems often have TPM available through firmware. Secure Boot also depends on UEFI configuration. Microsoft explains that some systems may simply have Secure Boot disabled or configured through an incompatible Legacy/CSM mode.
Where possible, enabling the required security features is preferable to bypassing them.
Disconnect the Network When Necessary
If your goal is to use a Rufus-prepared installation with local-account setup options, temporarily disconnecting Ethernet and Wi-Fi during the relevant Windows setup stage may be necessary.
Rufus specifically documents that the local-account behavior can depend on the installer being unable to access the internet during account creation.
This does not mean Windows should remain permanently offline. Reconnect to the internet after installation when appropriate so that Windows Update, security updates, drivers, activation, and other required services can function normally.
Boot the PC from the Windows 11 USB
Open the Boot Menu
Insert the bootable USB into the computer where Windows 11 will be installed.
Restart the computer and open its temporary boot menu. The required key varies by manufacturer and model, so common keys include F12, F11, F9, Esc, or a manufacturer-specific key.
Select the UEFI entry corresponding to the Windows installation USB when multiple boot choices are displayed.
Start Windows Setup
Once the computer successfully boots from the USB, the Windows Setup environment should appear.
If the system immediately boots into the existing operating system, the boot order or temporary boot selection may need to be adjusted.
Choose Windows 11 Setup Preferences
Select Language and Regional Settings
Windows Setup will ask for language, time and currency format, and keyboard layout.
Choose the settings appropriate for your location and keyboard.
These choices can be changed later, but selecting them correctly now makes the installation process smoother.
Start a Fresh Windows 11 Installation
Choose the option to install Windows 11.
If setup asks for a product key and you are reinstalling a properly licensed device, use the appropriate option for your licensing situation. Do not use unofficial activation methods.
Windows edition selection should match the license available for the computer. Choosing Windows 11 Pro on a device licensed only for Home does not automatically provide a valid Pro license.
Select the Windows Installation Drive Carefully
Identify the Correct Disk and Partitions
This is the stage where extreme care is required.
A clean installation can remove existing partitions and data. If you see multiple drives, identify the correct one by capacity and other known characteristics before deleting anything.
Do not assume that Disk 0 is always the drive you intend to erase.
Delete Existing Partitions Only When You Have a Backup
For a true clean installation, the target drive can be cleared so Windows Setup can create a new partition structure automatically.
Deleting partitions is destructive.
Only do this after confirming that the drive contains no data you need.
Once the intended target disk shows unallocated space, select the appropriate unallocated space and continue with the installation.
Let Windows 11 Complete the Installation
Windows will copy files, expand the installation image, configure the system, and restart several times.
Do not remove the USB during the early boot stages unless the installer has already completed the required USB-based phase.
If the computer repeatedly boots back into Windows Setup, remove the USB after the installation has successfully transferred to the internal drive, or select the internal Windows Boot Manager from the boot menu.
Complete Windows 11 First-Time Setup
Choose Country and Keyboard
After installation, Windows will return to the initial setup process.
Confirm your country or region and select the correct keyboard layout.
If Windows asks about adding another keyboard layout and you do not need one, you can normally skip it.
Create the Appropriate User Account
On supported installation paths, the setup may allow you to create a local user account rather than immediately requiring an online Microsoft account.
However, Microsoft has changed the Windows 11 setup experience over time, and Rufus has also documented compatibility differences between Windows versions. Therefore, account-creation behaviour should be treated as version-dependent rather than guaranteed.
Do not use unofficial scripts or suspicious activation tools just to create an account.
Check the Fresh Windows 11 Desktop
Once setup is complete, Windows 11 should load into the desktop.
A clean installation can provide a much fresher starting point than a heavily customised old installation, but it does not automatically guarantee better performance.
Actual performance depends on the CPU, RAM, storage device, graphics hardware, drivers, background applications, and Windows configuration.
Remove Unwanted Built-In Applications Safely
Review the Start Menu
Open the Start menu and review the applications that are present.
Some users may want to remove applications they do not use, such as certain consumer apps or optional services.
Use normal Windows settings or supported uninstall methods instead of deleting system files manually.
Uninstall Apps from Windows Settings
Open Settings > Apps > Installed apps and review the application list.
Where Windows provides an Uninstall option, use it.
This approach is safer than using aggressive debloat scripts that can remove shared components or create future update problems.
Clean Up the Start Menu
Windows 11 also allows you to manage the Start menu and remove unwanted pinned items.
Right-click an item and choose the appropriate action, such as unpinning it.
This changes the user interface without unnecessarily removing Windows components.
Review Microsoft Edge, OneDrive, Outlook, Teams, and Other Apps
Applications such as OneDrive, Outlook, Teams, Edge, and other Microsoft components may be present depending on the Windows edition, release, region, and installation state.
Not every component can or should be removed.
For example, some Windows components are deeply integrated with the operating system, while others are ordinary applications that can be uninstalled or disabled through supported settings.
The practical approach is to remove only what you genuinely do not need.
Check Fast Startup After Installation
Fast Startup is a Windows power-management feature intended to reduce boot time by using a hybrid shutdown mechanism.
The original script suggests disabling Fast Startup because it can contribute to certain troubleshooting situations.
However, disabling Fast Startup is not universally required. If your system is stable and boots normally, there is no general rule that every Windows 11 installation must have Fast Startup disabled.
For troubleshooting, dual-boot compatibility, or certain shutdown-related problems, disabling it can be a useful test.
You can review the setting under:
Control Panel > Hardware and Sound > Power Options > Choose what the power buttons do
The exact interface can vary between Windows builds.
Install Drivers and Windows Updates
A newly installed Windows system should not be considered finished until the hardware is checked.
Run Windows Update
Open Windows Update and install the available security updates, cumulative updates, and supported driver updates.
Microsoft recommends using supported installation methods and keeping the operating system updated.
Install Manufacturer Drivers When Necessary
For important components such as graphics, chipset, Wi-Fi, Bluetooth, storage controllers, and specialized hardware, the computer manufacturer's official support page or the hardware manufacturer's official website is usually the best source for compatible drivers.
Avoid random “driver updater” websites and suspicious installer packages.
Verify Device Manager
Open Device Manager and check for devices with warning icons.
A clean Windows installation can leave some hardware without the final manufacturer-specific driver.
Pay particular attention to:
Graphics adapter
Network adapter
Wi-Fi
Bluetooth
Audio device
Chipset-related devices
Touchpad or touchscreen
Storage controller
Resolving these driver issues can make a much larger practical difference than removing a few optional applications.
Important Tips for a Reliable Windows 11 Clean Install
Use Genuine Installation Media
The Windows ISO should come from Microsoft's official download page whenever possible. Microsoft specifically provides the ISO for users who want to create bootable installation media.
Verify the USB Drive Before Formatting
A surprisingly common mistake is selecting the wrong USB or external disk in Rufus.
Always check the device name and capacity before confirming the format.
Prefer Official Hardware Support Over Bypasses
If TPM 2.0 or Secure Boot is available but disabled, enabling the feature through the system firmware is generally preferable to bypassing the requirement.
Microsoft states that TPM 2.0 and UEFI/Secure Boot are part of the official Windows 11 requirements.
Do Not Treat a Bypass as an Official Compatibility Approval
A Rufus-created installation can alter how setup handles certain checks, but that should not be confused with Microsoft certifying the hardware as compatible.
Microsoft recommends installing Windows 11 on devices that meet its minimum requirements.
Avoid Aggressive Debloat Tools
Removing every Microsoft application is not automatically the same as optimizing Windows.
Some components are related to updates, system functionality, security, or other Windows services. A stable installation is more valuable than an extremely stripped-down installation that later develops update or driver problems.
Keep a Recovery Plan
After a successful installation, create a sensible backup or recovery strategy.
A clean Windows installation can be much easier to maintain when important files are stored separately and a known-good backup is available.
When a Clean Install Is Better Than an Upgrade
A clean installation is especially useful when:
Windows has accumulated serious software problems.
The existing installation is unstable.
Malware or unwanted software has compromised the system.
You are replacing a heavily customised setup.
You want to completely rebuild the operating system.
You are comfortable reinstalling applications and restoring personal files.
An in-place upgrade is usually more convenient when preserving applications and user settings is more important than starting from scratch.
Microsoft supports multiple Windows 11 installation methods and recommends the appropriate supported method for compatible systems.
What You Should Expect After the Installation
A properly completed clean Windows 11 installation should give you a fresh operating system environment with a newly configured user profile and a clean application state.
If Rufus customisation options were used, some setup restrictions or optional components may behave differently from a completely standard Microsoft installation.
The most important thing is not how many applications disappeared from the Start menu. The real goal is a stable, secure, updatable Windows installation that works correctly with the computer's hardware.
Official Sources
For the Windows 11 ISO and installation information, use Microsoft's official Windows download and support resources. Microsoft documents the current Windows 11 requirements, installation methods, TPM requirements, and Secure Boot guidance.
For Rufus, use the official Rufus project website or its official GitHub repository. The project repository lists current releases and technical documentation about Windows installation options.
Note Point: Rufus can simplify Windows 11 installation media creation, but hardware requirements, licensing, backups, and system compatibility should always be considered before installation.
Disclaimer: This guide is for legitimate Windows installation and troubleshooting purposes; always use genuine Microsoft software and verify important files and hardware before making destructive changes.
