Ok, thanks for the quick response.
You don't need to worry about that step as your device already uses a 64-bit bootloader (note: the article you link to is for Intel Atom devices).
If you can outline what you actually want I'll try and help. Some questions I have are:
- do you want to run Ubuntu (or Lubuntu) as your main OS?
- do you want the OS to be installed on the in storage (eMMC) of the device or from a USB or micro SD card?
- do you need to dual-boot with another OS?
- are you concerned about storage limitations and want to run the OS across multiple storage (e.g internal plus micro SD card)?
- are you trying to install from a USB or from a micro SD card?
otherwise simply 'dd' the latest Canonical Ubuntu (or Lubuntu) ISO to a USB and boot from it by selecting the USB from the 'F10' menu and then install to the internal storage by double-clicking on the desktop's 'Install' icon once booted. Your device works with Ubuntu (or Lubuntu) OOTB and does not require anything special for installation.
Okay. Sure, no problem.
- Lubuntu as main OS, but Ubuntu will do.
- Either, the SD card wont be used for anything else.
- No as it is just being used to display network graphs
- I've tried installing from an SD card and from a USB card reader with an SD card.
I've tried this using Etcher but when I press F10 nothing shows up.
Thank you for your response, I'm contemplating sending it back.
First I recommend using a USB rather than a micro SD card as on some devices/models the bootloader cannot 'see' the micro SD card at boot and only 'sees' it once booted (I cannot remember whether this is also the case for your device/model).
Secondly if you cannot use a Linux machine to write the Ubuntu/Lubuntu ISO to the USB using the 'dd' command then I recommend using 'Rufus' on Windows.
Ubuntu (or one of its flavours) works well on your device so persevere rather than sending it back.
