Bootable Windows USB from Mac OSX (Terminal)

How to create an Bootable Windows USB from OSX without Bootcamp

You will need

  • USB SSD with at least 8GB
  • Windows .ISO

With this on hands

Open terminal and do the following:

diskutil list

This will list your mountable disks on your Mac, discover which is the path of your USB stick and then: IMPORTANT: The value will be something like: /dev/disk10 (the number is what identify your disks, be carefull).

diskutil unmountDisk /dev/disk10

Next open and terminal and use:

sudo dd if=PATH_TO_WINDOWS10_ISO of=USB_MOUNT_PATH bs=1m

This is what the final command should look like:

sudo dd if=/Users/joao/Downloads/pt_windows_10_education_version_1511_x64_dvd_7224110.iso of=/dev/disk5 bs=1m

Next press enter, its going to ask for your password, enter your password and hit enter. This will start the process.

You need to be patient when I first did this on a USB 2.0 it took 39 minutes. This time because i was curious I used a USB 3.0 and it took 21 minutes

When its finished you will see the bytes transferred, the time it took in seconds, and the bytes/sec.

Finally, you have one more step. In terminal you want to type

diskutil eject /dev/disk10

This will eject the disk, and you can remove it from the USB port. For verification, I reinserted the USB, opened it up, and this is what you should see

Congratulations

You now have a bootable Windows 10 USB drive.
