(How to Create a Linux Bootable USB) A Linux bootable USB drive enables you to both install and execute Linux on a computer system while keeping the original operating system intact. A bootable USB serves as an essential tool for everyone who works with Linux because it enables system installation and distribution testing and system troubleshooting.
This guide explains the entire process for making a Linux bootable USB drive through different methods that work on all platforms including Windows, macOS, and Linux.
What You Need
For your upcoming task, you will need several items including a USB drive of at least 4GB capacity and an official Linux ISO file from ubuntu.com. In addition, you will require either Rufus or Balena Etcher or command line software and emergency backup of your USB contents.
✔ A USB drive (at least 4GB; preferably 8GB+)
✔ A Linux ISO file (Download from the official website, e.g., Ubuntu: ubuntu.com)
A tool to create the bootable USB requires either Rufus or Balena Etcher the command line or any other similar boot USB builder.
This intervention requires a backup of your USB storage contents because the process will completely wipe out the present data.
Method 1: Creating a Linux Bootable USB on Windows
Step 1: Download Rufus
- Rufus offers users a zero-cost software solution to produce USB bootable systems.

- File System: Select FAT32 (default).
- The Boot Mode setting can be left at default values unless alternative instructions are provided.
Step 5: Create the Bootable USB
- Proceed to verify the operation when Rufus prompts for confirmation.
- Rufus both creates the new partition table and writes the Linux installation system.
- After the bootable USB is finalized you can begin using it.
Method 2: Creating a Linux Bootable USB on macOS
Step 1: Download and Install Balena Etcher
- Users should obtain Balena Etcher at balena.io and install the software.
- Plug in your USB drive.

- Open a terminal and run:
- Look for your USB device (e.g.,
/dev/sdb).
Step 2: Format the USB
- Replace
/dev/sdXwith your actual USB device:
Step 3: Create the Bootable USB Using dd
- ⚠ Warning: Be careful with
ddas it can erase the wrong disk if misused.
Step 4: Eject the USB

- Set USB as the primary boot device under “Boot Options.”
- Turn on your system after you save changes because it will start in Linux mode.
Conclusion
You can easily create a Linux bootable USB with the help of Rufus and Balena Etcher or through the Linux terminal. You must understand how to make a bootable USB since both installation and troubleshooting Linux requires it.
