Unable To Install To USB

Solution 1:

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.

Solution 2:

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.
