I needed to create a bootable pendrive with Windows 10 to format a PC. To carry out this operation I had only a Mac at my disposal, so I had to find a solution that met this need. Until a few years ago this operation was very simple, it was enough to use Bootcamp, the Apple assistant to install Windows on Mac.
Starting with macOS Sierra, Apple has removed the possibility of creating a Windows 10 installation disk using Bootcamp. Therefore, it was necessary to find other solutions. If you also need to do this from a Mac, don't worry, because in this guide you will be given an alternative method that will lead to the same solution. Let's find out the procedure that will allow you to create bootable Windows 10 pendrive from Mac without Bootcamp.
Create bootable Windows 10 pendrive from Mac
To create bootable Windows 10 pendrive from Mac you first need to download Windows 10 in ISO format. You can do it for free and legally directly on the Microsoft website.
Get a pendrive of at least 8GB (the Windows 10 installation file weighs about 5GB). Make sure you save all the data contained in it because the pendrive will be formatted.
Guide to create the bootable pendrive
Creating a Windows 10 startup disk is not a simple operation but it will guide you through all the steps. To obtain the final result it is necessary to use the terminal integrated in macOS.

- Start the application Terminal. You find it in Applications -> Utility -> Terminal.

- You will be shown a list containing all the devices connected to your Mac. Search for your pendrive and mark the name assigned to it. in my case the name disk2.
- Type this new command in the terminal (replacing disk2 with the name you found in the previous step) and press enter.

- The pendrive will be formatted and given its name Windows 10.
- At this point, double-click on the Windows 10 ISO file. It will be mounted on the desktop with the name of CCCOMA_X64FRE_IT-IT_DV9.
- Always in the terminal type the following command (if the name of the disk mounted on Windows differs from that indicated above, be sure to replace it in the command).
cp -rp /Volumes/CCCOMA_X64FRE_IT-IT_DV9/* /Volumes/WINDOWS10/
Wait for the terminal to complete the entire transfer operation on the pendrive. It may seem that the Mac has crashed but not so.
The length of the procedure differs depending on the speed of your disk. At the end of the procedure you can disconnect the pendrive from the Mac and use it to install Windows 10 on your PC.
