GRUB-2.06 for EFI

Introduction to GRUB

The GRUB package provides GRand Unified Bootloader. In this page it will be built with UEFI support, which is not enabled for GRUB built in LFS.

This package is known to build and work properly using an LFS-11.0 platform.

User Notes:

Installation of GRUB

First, install font data as the root user:

mkdir -pv /usr/share/fonts/unifont &&
gunzip -c ../unifont-13.0.06.pcf.gz > /usr/share/fonts/unifont/unifont.pcf


Unset any environment variables which may affect the build:


Don't try tuning this package with custom compilation flags: this package is a bootloader, with low-level operations in the source code which is likely to be broken by some aggressive optimizations.

Build GRUB with the following commands:

./configure --prefix=/usr        \
            --sysconfdir=/etc    \
            --disable-efiemu     \
            --enable-grub-mkfont \
            --with-platform=efi  \
            --disable-werror     &&

This package does not have a test suite providing meaningful results.

Now, as the root user:

make install &&
mv -v /etc/bash_completion.d/grub /usr/share/bash-completion/completions

Command Explanations

--enable-grub-mkfont: Build the tool named grub-mkfont to generate the font file for the boot loader from the font data we've installed.



If the recommended dependency FreeType-2.11.0 is not installed, it is possible to omit this option and build GRUB. However, if grub-mkfont is not built, or the unicode font data is not avaliable at the time GRUB is built, GRUB won't install any font for the boot loader. The GRUB boot menu will be displayed using a coarse font and the early stage of kernel initialization will be in blind mode — you can't see any kernel messages before the graphics card driver is initialized. It will be very difficult to diagnose some boot issues, especially if the graphics driver is built as module.

--with-platform=efi: Ensures building GRUB with EFI enabled.

Configuring GRUB

Using GRUB to make the LFS system bootable on UEFI platform will be discussed in Using GRUB to Set Up the Boot Process with UEFI.
