Creating a Windows 11 bootable USB on a Mac might seem like a daunting task, but it’s actually quite straightforward.

How to Create a Windows 11 Bootable USB on Mac

In this tutorial, we’ll walk through the process of creating a Windows 11 bootable USB on a Mac in clear, easy-to-follow steps. By the end, you’ll have a USB drive that you can use to install or repair Windows 11 on any compatible PC.

Step 1: Download Windows 11 ISO

First, download the Windows 11 ISO file from the official Microsoft website.

Make sure you choose the correct version that matches your needs. The ISO file is essentially a digital copy of the Windows 11 installation disc.

Step 2: Insert USB Drive

Next, insert your USB drive into any available USB port on your Mac.

Ensure the USB drive has at least 8GB of free space and no important data, as it will be wiped clean during the process.

Step 3: Use Disk Utility to Format USB Drive

Open Disk Utility on your Mac, select your USB drive, and choose "Erase". Format it to "MS-DOS (FAT)" and set the Scheme to "Master Boot Record."

Disk Utility is a built-in macOS tool that helps you manage your disks and volumes. Formatting ensures your drive is compatible with the Windows OS.

Step 4: Download and Open UNetbootin

Download UNetbootin, a free tool for creating bootable USB drives, from its website. Open the application once downloaded.

UNetbootin is cross-platform and works perfectly on macOS, making it ideal for this task.

Step 5: Create Bootable USB

In UNetbootin, select "Diskimage," then browse to and select your Windows 11 ISO file. Choose your USB drive from the dropdown menu and click "OK."

This step writes the Windows 11 installation files onto your USB drive, making it bootable.

Step 6: Wait for the Process to Complete

Wait for UNetbootin to finish creating the bootable USB. This may take several minutes.

Patience is key here! Don’t interrupt the process, as it could corrupt the data on your USB drive.

Step 7: Safely Eject the USB Drive

Once the process is complete, safely eject your USB drive from your Mac.

Properly ejecting ensures no files are being written and prevents corruption.

After completing these steps, your USB drive will be bootable and ready to install or repair Windows 11 on any compatible PC. You can now use it to boot into Windows setup and follow the on-screen instructions.
