You can get a Windows 11 ISO and create a bootable install disk.
Whether you're building a new Windows PC or just want to make a completely fresh start on your existing computer you will need to perform a clean install of Windows 11, booting off of an install disk and writing the new OS to your storage drive. In order to create a bootable install disk, you will need to get a Windows 11 ISO file that you can write to a USB Flash drive or use as a standalone file if you are installing Windows in a virtual machine.
First, you can download a Windows 11 ISO directly from Microsoft or use the company's Media Creation Tool to download the software and write it directly to a USB Flash Drive.
Second, you could use tools from a site called UUP dump to download the files from Microsoft's update servers and build a custom ISO that's fully up-to-date with an insider build that's even newer than release build. Finally, you can use Aveyo's open-source Universal MediaCreationTool to create an ISO that bypasses WIndows 11's TPM requirement.
Below, we'll show you all the ways you can get a Windows 11 ISO and write it to an installation disk.
How to Get a Windows 11 ISO
Before you can begin your install, you need to get a Windows 11 ISO file. If you've installed Windows 10 or even a build of Linux before, you'll know that ISO files are disk images you can use to create a bootable USB Flash drive, write to an optical disc or boot a virtual machine off of.
Downloading a Windows 11 ISO From Microsoft
The easiest way to get a Windows 11 ISO is by downloading one directly from Microsoft.
1. Navigate to the Windows 11 ISO page(opens in new tab).
2. Select Windows 11 from the menu under "Download Windows 11 Disk Image (ISO)." If you want to go straight to creating a USB Flash drive, you can download the Windows 11 Installation Media tool from here. See the section below for step-by-step details on how to do that.
3. Click Download.
4. Select your language and click confirm.
5. Click the download button that appears.
The ISO file will now download to your computer.
If you don't want to keep a copy of the latest Windows 11 ISO on your storage drive and just want to have a bootable USB Windows 11 install disk, the easiest way is to use Microsoft's media creation tool. Here's how.
1. Connect a USB Flash drive to your PC. It must be at least 8GB and have no data on it you want to keep. This process will overwrite the whole disk.
2. Navigate to Microsoft's Windows 11 Download page(opens in new tab).
3. Click Download Now under Create Windows 11 Installation Media to download the Media Creation Tool.
4. Launch the Media Creation Tool.
5. Click Accept when shown the license agreement.
6. Select your language and Edition and click Next. The default choices will probably be correct.
7. Select USB flash drive and click Next. You can also select ISO file here and create an ISO file instead if you don't have a drive ready.
8. Select your USB Flash drive (if there's more than one choice) and click Next.
You will now have to wait several minutes while your computer downloads Windows 11.
9. Click Finish when it says your USB Flash drive is ready.
Creating a Windows 11 ISO with UUP Dump
If you download a Windows 11 ISO from Microsoft, you'll always get the latest release version, but what if you want to do a clean install from a Windows 11 Insider Release Preview, Beta or Dev channel build? A very helpful site called UUP Dump allows you to download any build as an ISO file you can use for installation.
The ISO files actually come directly from Microsoft's servers as UUP Dump just gives you a batch file that downloads all the necessary files and turns them into an ISO. Here's how to use it.
1. Navigate to uupdump.net.
2. Scroll down to find the recent build you want. You almost certainly want the amd64 (aka x64) version of any build. If you are planning to install Windows 11 on a Raspberry Pi (an uncommon scenario), you should click arm64 instead of x64.
Or, alternatively, you can click the x64 button next to the build version you want. There are four choices:
- Latest Public Release Build: This is the release, not necessary to get from UUP Dump.
- Latest Release Preview Build: This is the closest Insider build to being final.
- Latest Beta Channel Build: A level between the newest and most polished versions.
- Latest Dev Channel Build: The newest but also possibly buggiest build available.
3. Select the language and click Next.
4. Choose the edition(s) you want and click Next. By default, your ISO will contain both Windows Home and Pro versions, but you can save space by picking just one of them.
5. Select "Download and convert to ISO" and check "Include updates" and then click "Create download package." A small zip file will download to your PC. This is not the Windows 11 ISO, but it will be used to download it.
6. Unzip the file and place its contents in a dedicated folder. Make sure the folder name has no spaces in it.
7. Double-click uup_download_windows.cmd in the folder with the downloaded files.
8. Click "Run Anyway," if Windows warns you that this is an unrecognized app.
9. Click Ok if warned by Windows User Account Control.
A command prompt window will open, running a batch file that downloads all the necessary files from Microsoft and creates the Windows 11 ISO file for you. This process will take several minutes or perhaps longer, depending on your Internet connection.
10. Press 0 to exit when the script finishes downloading the Windows 11 ISO.
A Windows 11 ISO file will appear in the folder where you placed uup_download_windows.cmd.
Download a Windows 11 ISO That Bypasses TPM
If you're planning to use Windows 11 on a computer that doesn't have TPM support or installing Windows 11 in a Virtual Machine, you should use AveYo's Universal MediaCreationTool which automatically disables the TPM check.
1. Download the MediaCreationTool.zip from MediaCreationTool Github page(opens in new tab). You need to select Download Zip under the Code menu.
2. Extract MediaCreationTool.bat from the zip file and run it. If Windows flags the file as dangerous, select "run anyway."
3. Select 11 from the MCT Version menu.
4. Click "Auto ISO." Clicking Auto USB will write the file directly to USB for you.
5. Click Yes if prompted by Windows to allow CMD to make changes.
The media creation tool will launch and begin downloading.
The ISO file it creates will allow you to install Windows 11, even if you don't have TPM.
Making a Bootable Windows 11 Install Disk
Unless you're just installing Windows 11 onto a virtual machine, you will need to create a bootable Windows 11 install disk from the data in your Windows 11 ISO file. For that, you'll need an empty USB Flash drive that's at least 8GB.
To write or "burn" your ISO file to a USB Flash drive, it's best to use Rufus, a free, third-party utility that will take care of arranges the partitions properly and making the disk bootable. You can also use Rufus to bypass Windows 11's TPM and Secure boot requirements if you choose.
1. Connect your USB Flash drive. Please note that you will be erasing all the data on it.
2. Download and launch Rufus(opens in new tab) (it does not install).
3. Select your USB drive if it's not already selected by default.
4. Click Select and choose the ISO file from your storage drive.
4. Click Start at the bottom of the window.
5. Create a second partition and format it as NTFS. It should take all the remaining disk space.
6. Check remove requirement for TPM, 4GB and data collection if you want. These are optional, but recommended and you must click Ok.
7. Click Ok if warned that the process will destroy all data on your USB Flash drive.
Rufus will now take a few minutes to drive to your drive. When it is done, you will have a USB Flash drive that can boot to install windows.
Installing Windows 11 on the Target PC
1. Boot your target PC off of the USB installation drive. You may need to hit a key or re-arrange the boot order to boot from USB.
2. Select your language (if it's not already selected) and click Next.
3. Click Install now.
4. Enter your product key or click "I don't have a product key" if you don't have one. You can always enter it later or use Windows 11 as inactivated.
5. Select the Windows edition if given a choice of editions.
6. Accept the license agreement and click Next.
7. Select Custom Install if prompted.
8. Choose the installation drive and click Next.
The installer will copy some files and may reboot at this point.
9. Select your country or region (if it's not selected) and click Yes. Also, select your keyboard layout when prompted.
10. Name your device and click Next.
11. Sign in with your Microsoft account.
12. Create a PIN for quick logins.
13. Click "Set up as new device" (or you can restore a previous config).
14. Click Skip if asked to customize your user experience. This is not necessary.
15. Click Next on the Microsoft Account and OneDrive screen.
16. Click Skip for Now if Windows tries to get you to sign up for Xbox Game Pass
Windows should now reboot and give you the desktop. Note that this install process may vary based on when you install and what version.
