We are going to use the parted command as given below- sudo parted -lįrom the above list, /dev/sdb is the USB drive that we are going to make bootable. You can use any one of them to list and identify your USB drive. There are various tools like fdisk, parted, sfdisk, cfdisk, df, etc are available for listing and partitioning of a disk in Linux. In this article, we will discuss how to create a bootable USB drive using this tool in Linux or Unix. The best thing is that it comes preinstalled with many Linux distributions.
It is a powerful tool that can be used for various purposes like backing up and restoring a disk, converting data formats, converting the case of a file, etc.
In a Unix-like operating system, dd is a command-line utility that is used to convert and copy files. A bootable USB is required whenever there is a need for the installation of a new operating system or if we want to run an operating system live. To make a USB bootable generally, we use GUI applications such as Linux Live USB creator and other applications that are available for Linux, FreeBSD, and Windows. When I said clone, I mean dd command copies the whole partitioning information, filesystem data, and every bit of information as well, which is not possible to copy using file system copy. DD command is used to create a bootable disk from an existing image as it clones data from one disk or partition (or a disk image) to others at the byte or block level.
