Balena Etcher: Burn ISO to USB or Clone USB Drives

Use Balena Etcher to easily burn ISO files to USB or Clone your USB drives. Ever wondered how to burn an ISO file to create a bootable USB drive? Or perhaps you're looking for a simple tool to clone a USB drive? Etcher, a freely available software utility, makes both of these tasks as straightforward as possible for users of all skill levels.

What is Balena Etcher?

Balena Etcher is an easy to use, open source application designed for creating bootable USB drives from ISO or IMG files and for cloning existing drives. This versatile software is ideal for setting up a bootable USB for a new operating system, backing up a bootable flash drive, or replicating data onto a new device. Unlike more complex tools, Etcher offers a simple interface with clear, step by step step guidance, making it ideal for beginners and advanced users alike.

Balena Etcher is compatible with Windows, macOS, and Linux. Windows users can download the .exe file for direct installation, while Linux users can utilize the AppImage format for portability and ease of use. Mac users simply need to drag the downloaded app into the Applications folder to begin.

Etcher supports various disk image file formats such as .ISO, .IMG, and .ZIP. This versatility allows you to burn or clone nearly any disk image directly without needing to extract or convert files.

User reviews often highlight Balena Etcher’s simplicity and reliability. One user shared, “Balena Etcher is my go-to tool for creating bootable USB drives. It’s straightforward and works perfectly every time!”

However, it’s important to note that Etcher performs raw image writing—much like the "RawWrite DD" command, meaning it directly overwrites the selected drive. This process will erase all existing data on the destination drive. Furthermore, depending on the source file’s filesystem, the drive may not be usable for general file storage after the operation. For instance, if you write a Linux-based ISO to a USB drive, it may no longer be readable by Windows.

Caveats aside, since it creates a direct copy of the source, this software functions very well for the purpose of creating a bootable USB from an Image or ISO file. As well as for cloning a bootable flash drive.

How Does Etcher Compare to Alternatives?

While tools like Rufus (Windows-only) and YUMI are more widely used, Etcher stands out for its cross platform compatibility and straightforward user interface. Unlike some other tools, which might also require additional configuration, Etcher’s guided process ensures that even beginners can successfully create bootable drives with ease.

However, for specific use cases, other tools like Ventoy and YUMI offer unique features that Etcher does not provide:

  • Ventoy allows users to create a multi-boot USB drive that can hold multiple ISO files. Instead of rewriting the USB drive for each ISO, Ventoy uses a single drive where users can simply copy ISO files. At boot time, it provides a menu to select which ISO to boot. This makes it a convenient choice for those who frequently switch between different operating systems or tools.
  • YUMI (Your Universal Multiboot Installer) is another tool designed for creating multi-boot USB drives. It supports adding multiple ISOs and organizing them into categories, such as Linux distributions, diagnostic tools, or Windows installers. YUMI also allows users to add persistence to certain Linux distributions, enabling them to save changes across reboots.

While Etcher is ideal for creating single boot USB drives due to its simplicity and reliability, Ventoy and YUMI excel in situations where multi-boot functionality or persistent storage is required. Meanwhile, tools such as UNetbootin also make for a reliable alternative for users only focused on creating single ISO booting drives, particularly on Windows. Users should choose the tool that best fits their specific needs.

Troubleshooting Common Etcher Issues

Although Etcher is known for its reliability, there are some common issues users might encounter. Here's a quick guide on how to troubleshoot some of the most frequent problems:

USB Drive Not Recognized After Etching

After writing an ISO or IMG file to a USB, the drive may not show up in your operating system's file explorer. This is because the USB has been formatted to match the image’s file system, which might not be supported by your OS. To resolve this, you may need to reformat the drive. You can use tools like Diskpart (Windows) or Fdisk (Linux) to restore it to a usable state.

Etcher Fails to Write the ISO or IMG File

If you encounter an error message during the flashing process, ensure that:

  • Your USB drive has enough space to accommodate the ISO or IMG file.
  • The ISO or IMG file is not corrupted. Try downloading it again if necessary.
  • Run Etcher with administrator privileges, as access permissions can sometimes cause errors.

Slow Flashing Speed

If the writing process seems unusually slow, it could be due to the speed limitations of your USB drive or port. Ensure that you are using a USB 3.0 drive in a USB 3.0 port for faster performance. Additionally, closing other resource intensive programs may speed up the process.

Error: Drive Too Small

The software requires that the target USB drive has at least the same capacity as the source file size. If you encounter a "Drive Too Small" error, double check the capacity of the USB drive. If it is only slightly smaller, try a different USB drive with a larger capacity.

Verifying Flash Results

After completing the flashing process, an option is offered to verify the written data. If this verification fails, consider retrying the process with a different USB drive or downloading the ISO or image file again.

Balena Etcher is an intuitive tool, but like any software, it can occasionally run into issues. By following these troubleshooting tips, you can resolve most common problems and make the most out of this versatile application!
