This depends entirely on the image type. We do not install grub on the
filesystem images as that won't result in a working system. GRUB must be
installed to the MBR or the VBR of a disk or partition.

The way this currently works is you build a live image (.hddimg) which
uses syslinux and provides an installer. The installer runs a script
which installs grub to the physical boot media.

Improving this process is part of a larger discussion on image types and
image creation tooling.

If the installer method does not work for you, please articulate the
reasons why and what would be a better solution for your use case.

Thanks,

Darren
