Integrating with GRUB

This section describes the Yocto configuration needed to integrate with the GRUB bootloader.

Please consult the bootloader support section to find out if GRUB is supported on your platform and build configuration, and whether it is enabled by default.

Enabling GRUB

If GRUB integration is not already enabled, you can enable it by adding the snippet below to your build configuration. For instance, in your local.conf:

MENDER_FEATURES_ENABLE_append = " mender-grub mender-image-uefi"
MENDER_FEATURES_DISABLE_append = " mender-uboot mender-image-sd"

See the documentation on features for more information.

BIOS based systems

If using GRUB, Mender by default assumes that the system is using the UEFI boot standard. For systems using BIOS based booting, the mender-bios feature should also be enabled using MENDER_FEATURES_ENABLE.
