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? Balena 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 guidance, making it ideal for beginners and advanced users alike.
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 to Burn ISO to USB with Etcher
To Burn an ISO to USB, you will first need to Download Etcher utility from the project Home Page.
- Choose the option to Flash from file
- Browse to, and select your ISO file, and then click Open
- Choose Select target
- (1.) Click the box to set your Destination Drive
(2.) Then click Select
- Click Flash! to etch or burn the file to the destination USB drive.
If the ISO was etched successfully, you should now have a bootable USB.
How to Clone USB Drive with Etcher
To clone USB drive from within Windows the easy way, use the Etcher tool as follows:
Note: this will also work for cloning bootable USB drives.
- Choose Clone drive
- (1.) Click the box to set your Source Drive
(2.) Then click Select
- Choose Select target
- (1.) Click the box to set your Destination Drive
(2.) Next click Select
- Finally, click Flash! to clone the entire Source Drive to Destination.
If the cloning of your USB flash drive went well, you should now have an exact duplicate or cloned USB drive. If this was a cloned copy of a bootable USB drive, you can now see if you can boot from it. To try this:
- Proceed to restart your PC.
- During system post (just as text or boot logo first appears on the screen), use your motherboard hotkey to enter or access your system BIOS.
- From the device boot menu, set your USB drive as the first boot device, and save your changes, F10.
- Continue to boot your computer, starting and running from the operating system that resides on your cloned bootable flash drive.
With Etcher, creating bootable USB drives or cloning existing ones is simple, efficient, and accessible for anyone!
Restoring a USB Drive After Using Etcher
If your USB drive becomes unreadable after using Etcher, you can restore it to a usable state. Follow this guide to restore and fix an unreadable USB flash drive to make it usable again for regular file storage.
Troubleshooting Other Common 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!
