What is a bootable USB and why do I need it?

A bootable USB is a USB drive that contains a bootable operating system, allowing you to start a computer from the USB drive instead of the internal hard drive. This can be useful for a variety of purposes, such as installing a new operating system, troubleshooting a computer, or running a live operating system.

Having a bootable USB can be a lifesaver in situations where your computer’s internal hard drive is damaged or corrupted, and you need to access your data or perform repairs. Additionally, a bootable USB can be used to test out a new operating system before installing it on your computer, or to run a live operating system on a computer that doesn’t have an internal hard drive.

What are the requirements for creating a bootable USB on Linux?

To create a bootable USB on Linux, you will need a few basic requirements. First, you will need a USB drive with enough free space to hold the operating system you want to install. The amount of space required will vary depending on the operating system, but a minimum of 4GB is usually recommended. You will also need a computer running Linux, as well as a tool for creating the bootable USB.

Additionally, you will need to download the ISO file for the operating system you want to install. This can usually be done from the official website of the operating system. Once you have the ISO file, you can use a tool such as dd or Rufus to create the bootable USB.

What tools can I use to create a bootable USB on Linux?
