Why balenaEtcher?

Here at balena we have thousands of users working through our getting started process, we found there was no easy way for our users to flash an SD card that we could recommend to everyone.

So we built Etcher, an SD card flasher app that is simple for end users, extensible for developers, and works on any platform.
  • Create USB installation media from bootable ISOs
  • Install almost any OS to almost any flash drive
  • Offer an easy way for your users to flash your OS using our ‘Flash with Etcher’ feature

Frequently Asked Questions

What should I do if my flash in Etcher fails?

It depends how it fails. Most of the time, a failed flash is due to either a faulty drive or adapter. Retry. Then try with another adaptor, drive or card and usb port.

If you're flashing from an url and it fails, try downloading the file first and flash it again from file.

Sometimes, things might go wrong, and you end up with a half-flashed drive that is unusable by your operating systems, and common graphical tools might even refuse to get it back to a normal state. To solve these kinds of problems, we've collected a list of fail-proof methods to completely erase your drive in major operating systems.

Can I use Etcher on Windows, Linux or Mac?

Etcher works on Microsoft Windows 10 and later, Linux (most distros) and macOS 10.10 (Yosemite) and later. Make sure you download the correct version from our downloads section.

For Windows 7, 8 or 32 bits, the latest compatible version of Etcher is v7.9.0.

Do I need to format my SD card / thumb drive before using Etcher? 

No. But keep in mind that Etcher will erase the whole drive and replace the data.

Can Etcher make a bootable USB? 

Yes, as long as the file your flashing is bootable.

Can Etcher write Windows ISO?

Windows images are not bootable without extra treatment that etcher is not designed to do. If you need to make a bootable disk for windows you can find more information in our documentation.
