Best Way to Make a Windows 11 Bootable USB on a Mac Sonoma?

My father's Windows 11 laptop can't boot after installing the latest system update. He asked me to reinstall Windows 11 on it. I did this a few years ago with the Bootcamp Assistant app. However, I am unable to find the app on my MacBook Air M1 running the latest macOS Sonoma 14.0. It turns out Boot Camp is removed from Apple Silicon Mac.

Now, my question is, what is the best way to create a Windows 11 bootable USB on Mac Sonoma?

Burn ISO image to USB flash drive Windows 11

I am trying to do a clean install of Windows 11. My DVD does not work, and I think it is because of some corrupted files. I downloaded the correct ISO image, but it will only allow me the option of burning the image to a DVD. Windows help clearly states that the image can be burned to a DVD or USB flash drive. The installation instructions on the download page are a little garbled, but they seem to say that a flash drive will work. I sense that there is a bug, and Windows thinks it's good corporate policy to act ignorant and let people waste their time and find out on their own.

If you are stuck in creating a Windows 11 bootable USB from ISO on Mac or Windows computers, don’t worry, you have effective solutions to fix it and boot your computer normally.

What is a Windows 11 Bootable USB?

A Windows 11 boot USB (a copy of an ISO) is a USB flash drive that has been configured to be bootable and contains the complete Windows 11 installation setup, as well as a small, built-in operating system (a bootloader) that can start up your computer independently.

When you insert this drive and tell your computer to boot from it, it bypasses the existing operating system on your hard drive entirely. This lets you run the Windows installer, access recovery options, or run diagnostic tools. Thus, you can use the bootable USB to install Windows on a brand-new hard drive or repair a PC that won't start up normally. It's an essential piece of kit for any PC user.
