    Yes, you can install Ubuntu on an Intel W5 Pro Mini PC Computer Stick. However, because Intel Atom Z8350 devices use a 64-bit processor paired with a 32-bit UEFI firmware, a standard Ubuntu USB installer will not boot without modification. [1, 2, 3, 4]
    You will need a lightweight Ubuntu flavour like Lubuntu or Xubuntu to ensure smooth performance on the low-power hardware. [5, 6, 7, 8, 9]

    Phase 1: Prepare the Modified USB Installer

    You must manually add a 32-bit EFI bootloader to a 64-bit Linux image so the stick's BIOS can recognise it. [1, 10]
     
     
    1. Download a lightweight 64-bit Linux ISO, such as Lubuntu Desktop.
    2. Download Rufus to format your flash drive.
    3. Flash the ISO to your USB drive using Rufus with the partition scheme set to GPT and target system set to UEFI.
    4. Download the bootia32.efi file from an open-source archive like the lamadotcare bootia32 GitHub repository.
    5. Open your newly flashed USB drive in file explorer, navigate to the folder \EFI\BOOT\, and paste the bootia32.efi file inside it. [11, 12, 13, 14, 15]

    Phase 2: Configure the Mini PC BIOS

     
    1. Connect a USB Hub to your PC Stick to plug in your USB installer, a keyboard, and a mouse.
    2. Power on the stick and repeatedly press F2 or ESC to enter the BIOS.
    3. Go to the Security/Boot tab and Disable Secure Boot.
    4. Set your USB drive as the primary boot device, save changes, and exit. [4, 12, 16, 17]

    Phase 3: Install Ubuntu

     
    1. Press F10 or F7 during reboot to bring up the boot menu and select your USB drive.
    2. Select Try Lubuntu from the GRUB menu to ensure everything loads properly.
    3. Launch the installer from the desktop, choose your language, and select Erase disk and install to overwrite Windows.
    4. Crucial: Make sure you are connected to the internet via a USB Wi-Fi dongle or phone tethering during installation so Ubuntu can automatically fetch the required Realtek/Intel drivers for the built-in Wi-Fi and audio chips. [2, 12, 16, 18, 19]

    What to Expect Post-Installation

     
    • Performance: Lubuntu/Xubuntu will feel significantly faster and more responsive than Windows 10 on an Atom processor.
    • Potential Issues: Built-in audio over HDMI and the internal Wi-Fi/Bluetooth chip sometimes require manual driver loading after the first boot. If they don't work out of the box, open the Driver Manager tool in Linux to apply missing proprietary drivers. [2, 5, 20, 21, 22]
    If you want, I can provide instructions on how to create a persistent live USB to test Ubuntu without deleting Windows first.
