Creating a Bootable Window 8 ISO from Mac was quite easy back then where Mac OS X was in the trend. Later, Mac OS Mojave came into the picture, and the in-built Boot Camp Assistant is no longer supported.

Therefore the process to create Windows 10 bootable USB on Mac for pc from ISO became much more complex and tricky. However, irrespective of the process complexity, Since you are reading this guide, you don't have to worry about the complexity of the process to burn ISO to USB windows 10 using Mac.

But the thing is, creating a windows bootable USB from ISO on mac is quite tough. If you are doing it for the first time, you might end up getting different unknown errors.

Because Mac Computers have a different architecture than Windows Computers. Mac computers have got some discrepancies that make them vulnerable while operating on different files especially, the files that are created for Windows OS in the first place.

Apart from this, an ISO Image file contains fragmented and archive files compressed from an optical disk. In order to burn them to a USB, i.e., creating a bootable USB from ISO, segregation of the image files is required.

If you want to create a windows 10 bootable USB on Mac without any errors and don’t want to pay for any tools, you could go with the 4th Method i.e using Terminal. But it also has few disadvantages.

Method 4: Create Windows 10/8/7 Bootable USB on Mac Using “using Terminal”

In this process, you have to write a few lines of code to complete the process successfully.

Don't worry, you don't have to go through different internet guides to find the code. I have it all here for you.

  1. Connect the USB Drive to the Machine.
  2. Launch “Terminal” and Hit the following command:“diskutil list”

    launch terminal
  3. You'll see a list of drives that are connected to your Mac device, find the USB, and remember its “IDENTIFIER” Value aka Device Name.
  4. Hit the following Query, just change the device_name with your Device's Name.

    diskutil eraseDisk MS-DOS "WIN10" GPT device_name

    replace device name
  5. Here, you are formatting the USB drive and naming it "WIN10". Be very careful with the device name. The wrong entry could format your Mac's local drive.

  6. In this step, you need to have the address of your ISO file. Once you have it, hit the following command to mount the ISO file.

    hdiutil mount ~filelocation

    mount iso file

  7. In the above command, replace “filelocation” with the actual location of your file include the name of the extension. For instance, if your file is located in the downloads folder then your file location will be :/Download/Windows-10.iso

    • Don't get confused with the location, otherwise Terminal will throw an error.
  8. Once you have mounted the ISO file, hit the following.

    cp - rp /Volumnes/ESD-ISO/* /Volumes/WIN10

    mount iso file

  9. With this command, you are telling the terminal to copy the ISO file in the USB drive and it will automatically make it executable.

  10. The above step could take a couple of minutes, once it is completed, you have to unmount the ISO Image. Run the following command:

    hdiutil unmount /Volumes/ESD-ISO

    mount iso file

That's all, you have successfully created a bootable USB drive and you can use it for installing windows on any device now.

Teminal is very suitable for making Windows 10 bootable USB on Mac, but if you enter the wrong command, all data on the selected drive will be erased and all data will disappear within a few seconds. Therefore, this is not an ideal solution for beginners who are not familiar with the technical staff.
