# How to create a Windows 10 bootable pen drive from a macOS

## Download the Windows 10

You can download the ISO file straight from Windows. That's right - everything we're going to do here is 100% legal and sanctioned by Microsoft.

If you want an English-language version of the latest update of Windows 10, [you can download the ISO in this link](https://www.microsoft.com/en-gb/software-download/windows10ISO).

If you have a relatively new computer, you probably want the 64-bit version. If you're not sure, go with the 32-bit version to be safe.

If you want a non-English-language version of Windows, or want to get an older update version, [download this another ISO instead](https://www.microsoft.com/en-gb/software-download/windows10).

# Mac Terminal

From your Mac terminal run this command below to see what's the disk number, for example `/dev/disk2` or `/dev/disk3`. In my case, it's `disk2`.

Let's erase your pendrive running this command.

```
diskutil eraseDisk MS-DOS "WIN10" GPT /dev/disk2
```

For some hardware you will need an MBR format, you might be able to have it running this command instead.

```
diskutil eraseDisk MS-DOS "WIN10" MBR /dev/disk2
```

Let's prepare your ISO and move the content to your pendrive running these commands.

```
hdiutil mount ~/Downloads/Win10_1903_V1_English_x64.iso
rsync -vha --exclude=sources/install.wim /Volumes/CCCOMA_X64FRE_EN-US_DV9/* /Volumes/WIN10
```

You will need to use Wimlib in your MacOS, so let's install it and run it.

```
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install wimlib
mkdir /Volumes/WIN10/sources
wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim /Volumes/WIN10/sources/install.swm 3800
```

## Ready!

Now you have a bootable pen drive ready to be used on your PC.
