How to Create Bootable Live USB Drive in Ubuntu 18.04/18.10

Last updated: October 5, 2018

To do a fresh Ubuntu install, I’m always first burning the ISO image into USB drive, and then boot up with the USB drive and install Ubuntu into hard disk.

I used to use Unetbootin to create the startup USB drive. However, it has been dropped from Ubuntu repositories since Ubuntu 18.04 LTS. And Unetbootin .bin package is not well burning the ISO image in my case.

In this quick tutorial, I’m going to tell you that the default Gnome USB Creator can do the job easier and more straightforward:

1. First download Ubuntu iso from releases.ubuntu.com, and plug-in your USB drive.

2. Search for and launch usb creator (Start Disk Creator) in application menu:

3. When it opens, click the Other button and choose the downloaded ISO image.

Finally click the Make Startup Disk button to start burning the ISO into selected USB drive.

That’s it! When everything’s done, boot the USB drive in your machine and try or install Ubuntu.
