Etcher – Burn ISO to USB – Clone USB

Ever wondered How to Burn ISO to USB? How about Clone USB to USB? Etcher is a freely available tool that can be used to do both. Created by Balena, this open source direct image writing and disk cloning software can be used to write, or etch an image .img or .iso file onto a flash drive. And as mentioned, the utility can also function as a disk cloning tool. In that it can be used to easily clone from one drive to another of equal size or larger.

You should be aware that functionality is similar to using a destructive RawWrite DD command. Meaning that the utility will overwrite the content of the destination drive with whatever source file has been chosen. As a result, all existing content on the destination drive will be erased, wiped clean or deleted. Additionally, depending on the filesystem of the source, the device might not remain usable for file storage purposes.

After etching an ISO or IMG, the drive may no longer be detected by some operating systems. So, after playing around for a bit, you might find a need to restore and fix an unreadable USB flash drive.

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.
