# 6.60. GRUB-2.04

The GRUB package contains the GRand Unified Bootloader.

Approximate build time: 0.8 SBU
Required disk space: 161 MB

## 6.60.1. Installation of GRUB

Prepare GRUB for compilation:

    ./configure --prefix=/usr          \
                --sbindir=/sbin        \
                --sysconfdir=/etc      \
                --disable-efiemu       \
                --disable-werror

The meaning of the new configure options:

`--disable-werror`

  This allows the build to complete with warnings introduced by more recent Flex versions.

`--disable-efiemu`

  This option minimizes what is built by disabling a feature and testing programs not needed for LFS.

Compile the package:

    make

This package does not come with a test suite.

Install the package:

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

Using GRUB to make your LFS system bootable will be discussed in Section 8.4, “Using GRUB to Set Up the Boot Process”.
