Step 1: Download the Ubuntu ISO file

Open the Official Ubuntu website through any installed web browser and download the Ubuntu ISO through the following download link:

Click on any Ubuntu version you want to install. I’ve been using the “Download Ubuntu Server 22.04 LTS” link under Ubuntu Server. This will open the dialog to save the file. Select the Save file option and then click OK.

The .iso package will be saved in your Downloads folder.


Step 2: Open Ubuntu Terminal

Open your Ubuntu command line, the Terminal, either through the Ubuntu Application Launcher search or by using the Ctrl+Alt+T shortcut.

Before writing to your USB stick, ensure that it is not automatically mounted in Ubuntu. Insert the USB into your system, and then execute the following command to retrieve your USB's name.

$ df

Note: The last line in the output of my df command lists the USB that is mounted to my Ubuntu system.

Look for your pendrive in the list of storage devices. It is usually listed as '/dev/sdX' (where 'X' is a letter corresponding to your pendrive, e.g., /dev/sdb, /dev/sdc). Make sure you identify the correct device to avoid accidentally overwriting other drives.


Step 3: Unmount the USB if it is mounted

Before proceeding, unmount the pendrive to ensure that no data is being read or written during the process. To unmount, use the following command.

sudo umount /dev/sdX1

For example, I would use the following device name to unmount the USB:

$ sudo umount /dev/sdb1
Step 4: Navigate to the Download Directory

By default, the downloaded files are usually saved in the 'Downloads' directory. Change the current directory in the Terminal to the location where the Ubuntu ISO is saved. For example.

cd ~/Downloads


Step 5: Create a bootable Ubuntu stick

Now, it's time to make the pendrive bootable using the 'dd' command. Replace 'ubuntu.iso' with the name of the downloaded ISO file, and 'X' with the letter of your pendrive.

$ sudo dd bs=4M if=/path/to/ISOfile of=/dev/sdx status=progress oflag=sync

For example:

$ sudo dd bs=4M if=/home/hp/Downloads/ubuntu-22.04.2-live-server-amd64.iso of=/dev/sdb1 status=progress oflag=sync

Be extremely cautious while running the 'dd' command, as it can overwrite data on your hard drive if the wrong device is specified.


Step 6: Wait for the Process to Complete

The creation process may take some time, depending on the size of the ISO file and the speed of your pendrive. Be patient and wait for the Terminal to display a message indicating the completion of the process.


Step 7: Eject the Pendrive

Once the process is complete, eject the pendrive safely using the following command.

sudo eject /dev/sdX

Congratulations! Your bootable Ubuntu pendrive is now ready to use. You can now use it to install Ubuntu on other systems or boot into a live Ubuntu environment whenever needed.
