If your device is hard to use because of an issue, or if you want to switch out of the Dev Channel or stop receiving preview builds, you might need to use an ISO for a clean installation or in-place upgrade. ISOs are available for both Windows 10 Insider Preview Builds and for Windows 11 Insider Preview Builds.
If you're having certain issues that prevent you from downloading an ISO to your device, or you need to quickly set up a new device in the Windows Insider Program, a bootable USB made from a Windows Insider ISO file can help.
Connect a USB drive that's at least 8 GB. Back up any data on the drive you want to save, because any data on it will be erased.
Open Start menu. Search for and launch the Recovery Drive application.
When the application opens, uncheck the "Back up system files to the recovery drive." box and click Next.
Select your drive from the list and click Next.
You'll see a confirmation prompt. Click Create. When this completes your USB drive will now be in a bootable configuration. Next we'll add the contents of the ISO file to it.
Locate the ISO file you downloaded in step 1 above. Right-click the ISO file and select Mount.
The ISO file will be mounted as a new drive letter on your computer and open in a new File Explorer window.
Copy all the contents of the mounted ISO folder onto the bootable USB you just created.
Once the copy process is finished, you're all set. Now you can use it on a device.
To un-mount the ISO file, navigate to that drive letter in File Explorer. In the toolbar, click eject.
If you use this drive to upgrade a device that already has Windows on it, connect it to the device, open File Explorer, locate the drive, and launch setup.exe to get started.
If you use this drive to do a clean Windows install, connect it to the target device and reboot. You may also need to adjust your BIOS or UEFI settings to allow it to boot from a USB-based drive.
Clean installation with a Windows 11 ISO (Not an Insider Preview Build)
Back up all your files and applications. A clean install with a Windows 11 ISO will erase all of your files, settings, and applications.
Plan and execute an endpoint deployment strategy, using essential elements of modern management, co-management approaches, and Microsoft Intune integration.
