I’m trying to install on Gigagyte Brix-N2807. It’s funky hardware, x64 cpu but 32bit UEFI.

[code]Boost.Python error in job “bootloader”.  
\<class ‘subprocess.CalledProcessError’\>  
Command ‘grub-install --target=x86\_64-efi --efi-directory=/boot/efi --bootloader-id=Netrunner\_Core --force’ returned. non-zero exit status 1

This is not directly supported. 32bit uefi is a bit hard.  
You could try installing grub-efi-ia32 before executing the installer and see if it then is able to install grub successfully

Hi  
Could you try installing the Netrunner Desktop ISO? It should work with EFI boot. We will also update the Core ISO soon with EFI install capabilities.
