Can I create macos monterey bootable USB on a Windows 11 PC?

On Windows 11, you can use the diskpart and PowerShell utilities to manually copy the macOS .dmg file to create a bootable USB media that can be used to install macOS Monterey free of charge, with no additional software required. This is done by formatting the USB using diskpart and then manually writing the macOS Monterey installation files to the USB using PowerShell.

Prepare a 16GB or above USB drive and backup your data, get the macOS Monterey .dmg file from a trusted third-party source or a Mac with Monterey already installed.

When you're done, enter exit to exit diskpart. Then we can download and install the 7-Zip utility, right-click on the .dmg file, open the archive with 7-Zip, and extract the Install macOS Monterey.app content to the specified folder on the desktop. Next, we will run PowerShell as administrator and enter the Copy-It command. This will help make Monterey bootable USB from a Windows PC.

Copy-Item -Path C:\Users\YourName\Desktop\Monterey\* -Destination E:\ -Recurse .

Then open File Explorer to make sure the USB drive has the installation file, right click on the USB drive and select Eject. Insert the created USB into your Mac, reboot and hold down the Option key, select the USB boot disk in the startup interface, and follow the prompts to complete the system installation.

The biggest advantage of using this method to create a bootable macOS Monterey USB disk is that it costs absolutely nothing. The whole process is done with the tools built into Windows 11 and the 7-Zip software, without having to rely on other complicated third-party software. Moreover, everything is done locally, regardless of the network conditions. There are some command line operations involved, but I've provided you with detailed step-by-step instructions, so you'll be able to get started even if you're not familiar with them.
