In this article, we would discuss how to create a bootable USB with the help of Ubuntu’s Startup Disk Creator. Through a bootable USB we can install or upgrade existing installation of Ubuntu. In addition, we can plug USB stick in any Desktop/Laptop machine to run live images of supported Operating System. Apart from that, We can also repair our existing operating system through USB sticks.
We would make a Ubuntu Bootable USB stick. Prerequisites for making a bootable USB stick:
A. USB stick of size 4GB,
B. Download .iso extension file of any Ubuntu flavor.
C. Running Ubuntu Linux Distribution.
It is important to take the backup of data on USB stick. When we make a USB stick bootable, it would erase all the data already present. Also, we may not be able to use USB stick as a storage device any further. To make it a storage device again, We need to delete partitions either through command-line tools or with package GParted.
Insert USB stick and Launch Startup Disk Creator.
Now, we need to insert our USB stick. Then, launch Startup Disk Creator from your system’s main menu.
In the Startup Disk Creator application, locate your .iso extension file of any Ubuntu flavor by clicking on Other button. Your USB stick would get detected by itself. If you have already plugged in two or more USB sticks then, select the USB stick you want to make bootable. Then, click on Make startup disk button. In few minutes operation would get successfully completed.
