toc: false toc: false

There are a number of fantastic Windows applications for creating bootable USB drives from ISO images - but those don't work on a Chromebook. Fortunately there's an easily-available tool which will do the trick: Google's own [Chromebook Recovery Utility](https://chrome.google.com/webstore/detail/chromebook-recovery-utili/jndclpdbaamdhonoechobihbbiimdgai) app. There are a number of fantastic Windows applications for creating bootable USB drives from ISO images - but those don't work on a Chromebook.

Normally that tool is used to creating bootable media to [reinstall Chrome OS on a broken Chromebook](https://support.google.com/chromebook/answer/1080595) (hence the name) but it also has the capability to write other arbitrary images as well. So if you find yourself needing to create a USB drive for installing ESXi on a computer in your [home lab](https://twitter.com/johndotbowdre/status/1341767090945077248) (more on that soon!) here's what you'll need to do: Normally that tool is used to creating bootable media to [reinstall Chrome OS on a broken Chromebook](https://support.google.com/chromebook/answer/1080595) (hence the name) but it also has the capability to write other arbitrary images as well.

9. All done! It probably won't work great for actually recovering your Chromebook but will do wonders for installing ESXi (or whatever) on another computer! 9. All done!

You can also use the CRU to make a bootable USB from a `.zip` archive containing a single `.img` file, such as those commonly used to distribute [Raspberry Pi images](https://www.raspberrypi.org/documentation/installation/installing-images/chromeos.md).
