Balena Etcher is a popular software utility that allows you to easily write an ISO to USB or clone USB drives with minimal effort. In addition to USB cloning, this free and intuitive tool can also be used to flash operating system images to USB flash drives or SD cards.
The result is a bootable USB drive that can be run on virtually any computer that supports BIOS or UEFI booting from removable media. This makes it ideal for creating live Linux USBs, OS installers, rescue environments, and diagnostic tools.
Use Etcher to Clone USB Drives or Burn an ISO to USB
Balena Etcher is an open source disk imaging tool designed to make the process of creating bootable USB drives or SD cards as simple and error free as possible. It is well known for its clean interface and cross platform support, working on Windows, macOS, and Linux.
Unlike many traditional ISO to USB tools, Etcher focuses heavily on usability and safety. It reduces the risk of selecting the wrong drive and includes automatic validation to ensure that the written image is accurate and reliable.
