I am running Zorin 12.4 host and Ubuntu 18-04 guest.

I have set Zorin up to network boot in UEFI mode with the ipxe.efi boot loader. Now I am wanting to do the same with the VM.

I have set Network as the first boot option under Settings --> System but I am getting the error “NBP is too big to fit in free base memory”.

I have been told this error is caused by sending the wrong boot loader based on the target hardware. Meaning if the target computer is running in Legacy BIOS mode and it is sent the ipxe.efi boot loader (rather than undionly.kpxe for Legacy BIOS) you will see that error.

So my problem, as I understand it, is that Ubuntu is booting in Legacy Bios mode. The solution, presumably, is to get the VM booting in UEFI mode but I do not know how to achieve this.

Can it be done?

If I remember correctly, no, the EFI-boot from PXE isn't there yet...

See for example: Add UEFI PXE boot possbility and many, many more, if you had simply searched for it...

Nice invention that "search" thing, underutilized unfortunately...

I searched 'network boot' and 'UEFI boot' before posting.

search.php?keywords=network+boot&fid%5B0%5D=6

search.php?keywords=UEFI+boot&fid%5B0%5D=6

Neither search produced relevant results.

Oh, I see what you did there, you used the "Search" within the forums. Unfortunately the phpBB search doesn't work that well, don't use it. Instead use your favorite search engine, but simply add the "site:forums.virtualbox.org" at the end of it, something like:
https://www.google.com/search?q=EFI+PXE ... ualbox.org

FYI, I can not found a solution so I create one. Just search virtualbox-efi-netboot in github.
