Create a Bootable USB in Ubuntu Linux

This post describes the steps to create a startup disk in Ubuntu Linux.

Ubuntu Linux lets you create a bootable disk that you can use to restore your computer when there’s a problem. The flash drive must have at least 2GB of storage capacity to create a startup disk.

Any data on the USB flash drive will be erased or lost when you create a startup disk. So, ensure you’re not using a critical flash drive and don’t have any valuable data.

To create the disk, you must download an ISO image of the version of Ubuntu Linux you want to install or use to repair your local computer.

Below is how to use the Startup Disk Creator tool to create a startup disk in Ubuntu Linux.
