You will need:
  • 32 GB USB drive or larger with no data on it
  • 4 GB USB drive or larger with no data on it
  • Rufus utility
  • Lubuntu 19.04 LiveISO
  • System image you want to install
  • Computer running Windows XP or newer.

    Save the system image file to your 32gb or larger USB drive.

    Step 1
    Open Rufus Utility.

    Step 2
    In the "Device" box, select your USB drive which is 4gb or larger.

    Step 3
    Click the "Select" button and select the lubuntu-19.04-desktop-amd64.iso file you downloaded from above.

    Step 4
    Select option "GPT" in the "Partition type" selection box.

    Step 5
    Click "Start" button at the bottom of the window. Select "Yes" and/or "Ok" for any other messages you get.
    Once the green progress bar at the bottom says "READY", unplug your USB drive from your PC and plug it into your Atomic Pi along with a keyboard and mouse. (A USB hub may be required)

    Step 6
    Turn on your Atomic Pi by plugging it into power, then immediately press the ESC key until you see a blue and white BIOS screen, this may require multiple tries.

    Step 7
    Navigate to the "Boot" tab at the top using the arrow keys, then select "Boot Option #!" and press enter. Select your USB drive and press enter.

    Step 8
    Navigate to the "Save & Exit" tab at the top using the arrow keys, then select "Save Changes and Reset", then select "Yes" for the dialog box.

    Step 9
    The Atomic Pi should now boot to a screen with multiple options listed, select "Try Lubuntu without Installing".

    Step 10
    After boot completes, open a terminal from the menu and enter "lsblk" (without quotes) then press enter. You should get a result with an option /dev/mmcblk0 with a capacity of around 14gb. If you do not get that result, seek support from the Atomic Pi Discord.

    Step 11
    Open a file manager from the menu and click on your USB storage device, then close the file manager.

    Step 12
    Return to the terminal and run command "sudo dd if={location of image file} of=/dev/mmcblk0 bs=50M status=progress" where {location of image file} is the path to your system image file.

    Step 13
    Once flashing is finished, unplug your Atomic Pi and remove the 4gb or larger USB drive containing Lubuntu LiveISO.

    Step 14
    Done! Plug in your Atomic Pi, it should start the newly installed system image.
