How to Create a Live USB Ubuntu?

Ubuntu is a popular and user-friendly operating system that many people choose for their computers. While installing Ubuntu directly on a PC is the most common method, another convenient option is to create a Live USB of Ubuntu. This allows you to try out Ubuntu without making any permanent changes to your computer’s configuration. Whether you want to test Ubuntu, troubleshoot issues, or simply explore the operating system, creating a Live USB Ubuntu is a practical solution.

To create a Live USB Ubuntu, follow the steps below:

Step 1: Download the Ubuntu ISO file
Visit the official Ubuntu website and download the ISO file for the desired Ubuntu version you want to use. Make sure to select the appropriate architecture (32-bit or 64-bit) based on your computer’s specifications.

Step 2: Prepare the USB drive
Insert a USB drive with at least 4GB of storage capacity into your computer. Note that all the data on the USB drive will be erased during this process, so ensure you have a backup if needed. Open the Disk Utility (or equivalent) and format the USB drive to FAT32 or NTFS.

**Step 3: Create a bootable USB**
To create a bootable USB drive, you need to use a tool called “Rufus.” Rufus is a popular and reliable software for creating bootable USB drives. Download Rufus from the official website and install it on your computer.

Once Rufus is installed, open the program and select your USB drive from the Device dropdown menu.

**Step 4: Select the Ubuntu ISO file**
Click on the “Select” button next to the ISO image dropdown and locate the downloaded Ubuntu ISO file on your computer. Make sure you have selected the correct file.

**Step 5: Configure the settings**
Leave the default settings as they are in Rufus, including the Partition scheme (MBR) and File system (FAT32). If you’re using UEFI firmware, select the “GPT” partition scheme. It’s recommended to leave the rest of the settings unchanged unless you have specific requirements.

**Step 6: Create the Live USB**
Finally, click on the “Start” button in Rufus to begin the process of creating the Live USB Ubuntu. This may take a few minutes, so be patient.

Once the creation process is complete, you will have a bootable USB drive with Ubuntu. You can now restart your computer, enter the boot menu, and choose to boot from the USB drive. This will allow you to run Ubuntu directly from the USB drive, experiencing the operating system without installing it on your computer.
