If we ask the user to include the parenthesis in this definition, then the menuconfig vision of this option looks a bit weird, because string options are already enclosed in parenthesis, so it looks like: ((hd0,msdos1)) boot partition In menuconfig. Maybe we should instead ask for the value without the parenthesis, and add them in grub2.mk, so something like: config BR2_TARGET_GRUB2_BOOT_PARTITION string "boot partition" default "hd0,msdos1" Specify the partition where the /boot/grub/grub.cfg file is located. Use 'hd0,msdos1' for the first partition of the first disk if using a legacy partition table, or 'hd0,gpt1' if using GPT partition table. (Notice also that I added the word 'file' in the first sentence). > config BR2_TARGET_GRUB2_BUILTIN_MODULES > string "builtin modules" > default "boot linux ext2 fat part_msdos part_gpt normal biosdisk" if BR2_TARGET_GRUB2_I386_PC > diff --git a/boot/grub2/grub2.mk b/boot/grub2/grub2.mk > index 50f93ee..a686b5d 100644 > --- a/boot/grub2/grub2.mk > +++ b/boot/grub2/grub2.mk > @@ -11,9 +11,14 @@ GRUB2_LICENSE = GPLv3+ > GRUB2_LICENSE_FILES = COPYING > GRUB2_DEPENDENCIES = host-bison host-flex > > +GRUB2_BUILTIN_MODULES = $(call qstrip,$(BR2_TARGET_GRUB2_BUILTIN_MODULES)) > +GRUB2_BUILTIN_CONFIG = $(call qstrip,$(BR2_TARGET_GRUB2_BUILTIN_CONFIG)) > +GRUB2_BOOT_PARTITION = $(call qstrip,$(BR2_TARGET_GRUB2_BOOT_PARTITION)) > + > ifeq ($(BR2_TARGET_GRUB2_I386_PC),y) > GRUB2_IMAGE = $(BINARIES_DIR)/grub.img > GRUB2_CFG = $(TARGET_DIR)/boot/grub/grub.cfg > +GRUB2_PREFIX = $(GRUB2_BOOT_PARTITION)/boot/grub And then here, do: # Yes, the partition specifier needs to be enclosed in parenthesis.

Since boot partition was not specified, grub tools try to detect it automatically. This patch add an option to force it.
