There is seems a bug about GRUB installer after upgrade the kernel to 4.19. And the
console is lost, or can be used only through the serial port.
You can try to use the kernelflinger directly.

Celadon] GRUB installer issue
We built Celadon master branch for the GRUB installer image and tried to test on a
NUC6CAYH but the installer was never displayed after boot to usb drive. We built Celadon
master branch for the installer Kernel Flinger executables and was able to install Celadon
and successfully boot Celadon. We then built the omr1 branch for GRUB Installer and
removed the kernel parameter memmap=XXX and was able to see installer but it failed during
Is the GRUB installer working?
The build machine was Ubuntu 16.04.
