[yocto] Grub installation

[Jürgen Messerer]

Thanks for the tips.

As far as I know is at the moment the new grub default.
How can I configure back to the old version 0.97?

Best regards

Juergen

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
