Why Create a Bootable USB Drive?
Before we dive into the process, let’s discuss why creating a bootable USB drive is useful. Here are a few reasons:
- Try out Ubuntu without installing it: A bootable USB drive allows you to try out Ubuntu without installing it on your computer. This is a great way to test the operating system and see if it’s right for you.
- Install Ubuntu on multiple computers: If you need to install Ubuntu on multiple computers, a bootable USB drive can save you time and effort. You can simply plug in the USB drive and install the operating system on each computer.
- Create a rescue disk: A bootable USB drive can also be used as a rescue disk. If your computer is not booting properly, you can use the USB drive to boot into Ubuntu and troubleshoot the issue.
Requirements
To create a bootable USB drive in Ubuntu, you will need the following:
- A USB drive with at least 2GB of free space: The USB drive should have enough free space to hold the Ubuntu installation files.
- Ubuntu installation files: You can download the Ubuntu installation files from the official Ubuntu website.
- A computer with Ubuntu installed: You will need a computer with Ubuntu installed to create the bootable USB drive.
Method 1: Using the Startup Disk Creator
Ubuntu comes with a built-in tool called the Startup Disk Creator that allows you to create a bootable USB drive. Here’s how to use it:
Step 1: Open the Startup Disk Creator
To open the Startup Disk Creator, follow these steps:
- Open the Dash by clicking on the Ubuntu logo in the top left corner of the screen.
- Type “startup disk creator” in the search bar and select the Startup Disk Creator application.
Step 2: Select the USB Drive
Once the Startup Disk Creator is open, select the USB drive that you want to use from the list of available devices.
Step 3: Select the Ubuntu Installation Files
Next, select the Ubuntu installation files that you downloaded earlier. You can select the files from the “Source disc image (.iso) or CD” dropdown menu.
Step 4: Create the Bootable USB Drive
Once you have selected the USB drive and the Ubuntu installation files, click on the “Make Startup Disk” button to create the bootable USB drive.
Method 2: Using the dd Command
Alternatively, you can use the dd command to create a bootable USB drive. Here’s how:
Step 1: Open the Terminal
To open the terminal, follow these steps:
- Open the Dash by clicking on the Ubuntu logo in the top left corner of the screen.
- Type “terminal” in the search bar and select the Terminal application.
Step 2: Identify the USB Drive
Once the terminal is open, use the lsblk command to identify the USB drive:
bash
lsblk
This will list all the devices connected to your computer, including the USB drive.
Step 3: Use the dd Command
Once you have identified the USB drive, use the dd command to create the bootable USB drive:
bash
sudo dd bs=4M if=/path/to/ubuntu.iso of=/dev/sdx status=progress oflag=sync
Replace /path/to/ubuntu.iso with the path to the Ubuntu installation files, and /dev/sdx with the device name of the USB drive.
