GRUB EFI

The grub-efi boot method is used to boot a device via GRUB loaded from UEFI.

yaml - boot: method: grub-efi commands: nfs auto_login: login_prompt: "login:" username: root prompts: - 'root@stretch:'

Note

In most cases, starting GRUB from UEFI requires using the uefi-menu method as well. Admins can refer to the mustang-grub-efi.jinja2 device type template for an example of how to make selections from a UEFI menu to load GRUB.

Parameters

This boot method shares the same job parameter supported by the grub boot method.
