Create Bootable USB Drive With USBImager In Linux

Since the conception of Linux, so many of flavors in Linux operating systems are developed. Most of them can be downloaded from the internet. The downloaded Linux OS is usually a bootable ISO image. You can write it to either a CD or DVD or USB depending on the size of the ISO image. Nowadays, most of us use USB mass storage devices to write the bootable ISO images in Linux and Unix-like systems. There are many applications available to create bootable USB disks in Linux and each application has its own set of distinctive features. Today, we will discuss about one such tool called USBImager.

The size of this tiny application is around 170~ kb only. It doesn’t have any dependencies either. It makes synchronized writes, meaning, all data is on disk when the progress bar reaches 100%. It can verify writing by comparing the disk to images.

USBImager can read the RAW images, such as .img,.bin,.raw,.iso,.dd, etc., compressed images, such as .gz,.bz2,.xz,.zst etc, and archive files such zip (PKZIP and ZIP64). We can also create the backup of the entire USB drive. It is even possible to create compressed backups in raw and bzip2 formats.
