I am currently using Zorin OS 12.4 Core as the only Operating System on my ThinkPad X1 Carbon Gen 4 (20FC). I am trying install either Ubuntu 18.04.1 LTS or Ubuntu 18.10 on my pc and it says that that I need either a DVD drive or a USB port for the installer media. I tried to get it onto a USB but it won't let me install it to a USB. How do I install either Ubuntu 18.04.1 LTS or Ubuntu 18.10 on to my USB? DownloadUbuntuDesktop.jpg ImageBurningSetup.jpg

For a simple installer flash drive that will boot in UEFI:

  1. Insert flash drive, note it's location, likely sdb.

  2. Download an Ubuntu ISO file.

  3. cd to its directory.

  4. Run in terminal:

    sudo dd if=isofilename.iso of=/dev/sdb
    

    (assuming sdb is the USB)

  5. The process will take a while.

  6. When done, boot Ubuntu from the USB flash drive in UEFI mode and install.

  • The dd method is the general advice, that works in all linux distros and hybrid iso files. It is simple, but it is very important to double check the device letter of the output, because dd does what you tell it to do without questions and can easily overwrite valuable data, just because of a typing error.

You can install mkusb with the following commands in a terminal window. Zorin is similar enough to Ubuntu so that the same commands work (to install and run mkusb).

sudo add-apt-repository ppa:mkusb/ppa  # and press Enter
sudo apt-get update
sudo apt-get install mkusb mkusb-nox usb-pack-efi

You can start mkusb

  • from the menu or
  • from the command line in a terminal window

    mkusb file.iso
    

    or easier (more directly to version 12, dus

    dus file.iso
    

and it will help you to identify and select the target device.
