1. Download the Ubuntu image for your device in your `Downloads` folder

  2. Insert your SD card or USB flash drive

  3. Identify its address by opening the “Disks” application and look for the “Device” line. If the line is in the /dev/mmcblk0p1 format, then your drive address is: /dev/mmcblk0. If it is in the /dev/sdb1 format, then the address is /dev/sdb

  4. Unmount it by right-clicking its icon in the launcher bar, the eject icon in a file manager or the square icon in the “Disks” application
