Crafting an Unrivaled Bootable USB for Linux
If you’re a Linux enthusiast, you might have encountered a situation where you need to install or reinstall Linux on a computer, but the computer doesn’t have a CD/DVD drive. This is where a bootable USB for Linux comes in handy. A bootable USB for Linux is a USB drive that contains the necessary files to start and install a Linux distribution on a computer. In this article, you’ll learn how to create a bootable USB for Linux, step-by-step.
Creating a bootable USB for Linux might seem daunting, but it’s actually a straightforward process. All you need is an ISO image of the Linux distribution you want to install, a USB drive, and a tool to create the bootable USB. In the following sections, we’ll cover each step in detail.
Selecting an Operating System and Version
Before creating a bootable USB for Linux, you need to choose the operating system and version you want to install. Here are a few things to consider while selecting an operating system and version:
Popular Linux Distributions
Linux has many distributions, each with its own pros and cons. According to LinuxHint, some of the popular Linux distributions include:
- Ubuntu
- Linux Mint
- Debian
- Fedora
- CentOS
- Arch Linux
Choosing the Right Version
Once you’ve chosen the distribution, you need to select the right version. Here are some things to consider while selecting the right version:
- Is the version stable?
- Is the version compatible with your hardware?
- Does the version have the necessary features and software you need?
Some distributions have different versions for different purposes. For example, Ubuntu has a server version and a desktop version. Make sure you choose the right version for your needs. According to ZDNet, it’s important to choose the latest version of the distribution, as it will have the latest features, bug fixes, and security updates.
Downloading the ISO Image
The ISO image is a file that contains the necessary files for installation. Here’s how you can download the ISO image:
- Visit the official website of the Linux distribution you want to install. For example, if you want to install Ubuntu, visit the Ubuntu website.
- Click on the “Download” button.
- Select the version you want to download. Make sure you choose the right version and architecture (32-bit or 64-bit).
- Wait for the ISO image to download. The download time will depend on your internet speed and the size of the ISO image.
According to Linux Mint Installation Guide, it’s important to verify the integrity of the downloaded ISO image to ensure that it’s not corrupted. You can use tools like MD5SUM or SHA256SUM to verify the ISO image.
Choosing a Tool to Create Bootable USB
To create a bootable USB for Linux, you need a tool that can write the ISO image to the USB drive. Here are some commonly used tools:
UNetbootin
UNetbootin is a popular tool to create a bootable USB drive. It’s available for Windows, Mac, and Linux. Here’s how you can use UNetbootin:
- Download and install UNetbootin from the official website.
- Insert the USB drive.
- Open UNetbootin and select the distribution you want to install.
- Select the USB drive.
- Click on the “OK” button to start the process.
Rufus
Rufus is a popular tool to create a bootable USB drive on Windows. Here’s how you can use Rufus:
- Download and install Rufus from the official website.
- Insert the USB drive.
- Open Rufus and select the distribution you want to install.
- Select the USB drive.
- Click on the “Start” button to start the process.
Etcher
Etcher is a popular tool to create a bootable USB drive on Windows, Mac, and Linux. Here’s how you can use Etcher:
- Download and install Etcher from the official website.
- Insert the USB drive.
- Open Etcher and select the ISO image.
- Select the USB drive.
- Click on the “Flash” button to start the process.
dd
dd is a command-line tool available on Linux and macOS to create a bootable USB drive. Here’s how you can use dd:
- Open the terminal.
- Insert the USB drive.
- Run the command
diskutil list
to find the USB drive name. - Unmount the USB drive by running the command
diskutil unmountDisk /dev/diskX
(replace X with the USB drive number). - Run the command
sudo dd if=/path/to/iso of=/dev/diskX bs=1m
(replace /path/to/iso with the path to the ISO image and X with the USB drive number). - Wait for the process to complete.
Creating the Bootable USB
Once you have selected the tool to create a bootable USB, you can start the process of creating the bootable USB. Here are the steps to create a bootable USB:
- Insert the USB drive.
- Open the tool you selected to create a bootable USB.
- Select the ISO image you downloaded in section 3.
- Select the USB drive you inserted.
- Click on the “Create” or “Start” button to start the process.
The time it takes to create a bootable USB will depend on the size of the ISO image and the speed of the USB drive. According to ZDNet, the process can take anywhere from 5 to 15 minutes.
It’s important to note that creating a bootable USB will erase all the data on the USB drive. Make sure you have backed up all the data on the USB drive before creating a bootable USB.
Troubleshooting
If you encounter any issues while creating a bootable USB, here are some troubleshooting tips:
- Make sure you have selected the right distribution, version, and USB drive.
- Make sure the ISO image is not corrupted. Verify the integrity of the ISO image using tools like MD5SUM or SHA256SUM.
- Make sure the USB drive is not write-protected. Some USB drives have a physical switch that can make them write-protected.
- Make sure the USB drive is formatted to the right file system. The tool you are using to create a bootable USB should format the USB drive to the right file system, but you can also format it manually if needed.
Booting from the USB Drive
Once you have created the bootable USB, you can use it to boot into Linux. Here are the steps to boot from the USB drive:
- Insert the bootable USB in the machine you want to install Linux on.
- Turn on the machine and enter the BIOS or UEFI settings. The key to enter the BIOS or UEFI settings varies depending on the machine, but it’s usually F2, F10, or Del.
- In the BIOS or UEFI settings, go to the boot order or boot priority settings.
- Change the boot order or boot priority to boot from the USB drive first. Make sure to save the changes.
- Exit the BIOS or UEFI settings and restart the machine.
The machine should now boot from the USB drive and show the Linux installation screen. From here, you can follow the on-screen instructions to install Linux.
Troubleshooting
If the machine doesn’t boot from the USB drive, here are some troubleshooting tips:
- Make sure the USB drive is inserted properly and is recognized by the machine.
- Make sure the boot order or boot priority is set correctly in the BIOS or UEFI settings.
- Make sure the USB drive is bootable. You can test the bootable USB on another machine to make sure it works.
- Make sure the USB drive is formatted to the right file system. The tool you used to create the bootable USB should format the USB drive to the right file system, but you can also format it manually if needed.
If you encounter any other issues while booting from the USB drive, consult the documentation or support for the Linux distribution you are installing.
