Creating UEFI-Only Bootable USB Live Media for Ubuntu

Ubuntu 2

Creating a UEFI-only bootable USB live media for Ubuntu is a straightforward process that involves a few steps. This guide will walk you through the process, explaining each step in detail.

Quick Answer

To create a UEFI-only bootable USB live media for Ubuntu, you need to format the USB drive to FAT32, mount the Ubuntu ISO file, copy the files to the USB drive, and install the GRUB bootloader.

Prerequisites

Before you begin, you will need:

  • A USB drive with at least 4GB of storage
  • An Ubuntu ISO file
  • A system running Ubuntu

Formatting the USB Drive

The first step in creating a UEFI-only bootable USB live media is to format the USB drive. We will format it to FAT32, as this is the filesystem required for UEFI boot.

To do this, open the terminal and type the following command:

sudo mkfs.vfat /dev/sdX -I

Replace /dev/sdX with your USB drive’s device identifier. This command will format the USB drive to FAT32.

Mounting the ISO File

Next, you need to mount the Ubuntu ISO file. You can do this with the following command:

sudo mount -o loop /path/to/ubuntu.iso /mnt

Replace /path/to/ubuntu.iso with the path to your Ubuntu ISO file. This command will mount the ISO file to the /mnt directory.

Copying the Files

Now, you need to copy the files from the mounted ISO file to the USB drive. You can do this with the following command:

sudo cp -r /mnt/* /path/to/usb

Replace /path/to/usb with the path to your USB drive. This command will copy all the files from the ISO file to the USB drive.

Installing the GRUB Bootloader

The final step is to install the GRUB bootloader on the USB drive. This will make the USB drive bootable. You can do this with the following command:

sudo grub-install --target=x86_64-efi --boot-directory=/path/to/usb/boot /dev/sdX

Replace /path/to/usb with the path to your USB drive and /dev/sdX with your USB drive’s device identifier. This command will install the GRUB bootloader on the USB drive, making it bootable.

Conclusion

Creating a UEFI-only bootable USB live media for Ubuntu is a straightforward process that involves formatting the USB drive, mounting the ISO file, copying the files, and installing the GRUB bootloader. By following these steps, you can create your own UEFI-only bootable USB live media for Ubuntu.

Remember to replace the placeholders in the commands with your own paths and device identifiers. If you’re not sure about something, you can always refer back to this guide for help. Happy Ubuntu-ing!

Can I use a USB drive with less than 4GB of storage?

No, you will need a USB drive with at least 4GB of storage to create a UEFI-only bootable USB live media for Ubuntu.

Can I use a different filesystem other than FAT32?

No, FAT32 is the required filesystem for UEFI boot. Using a different filesystem may result in the USB drive not being recognized as bootable.

Can I use a different Linux distribution instead of Ubuntu?

Yes, you can use a different Linux distribution to create a UEFI-only bootable USB live media. However, the specific commands and steps may vary depending on the distribution.
