+
+== Changes for Cross-Tools Section ==
+
+This build is only required if you're using the Boot Method of the build.
+
+=== Build Grub Legancy ===
+
+{{{
+
+./configure --prefix=/usr \
+   --build=${CLFS_HOST} --host=${CLFS_TARGET}
+make
+make DESTDIR=${CLFS} install
+mkdir -v ${CLFS}/boot/grub
+cp -v ${CLFS}/usr/lib/grub/*/stage{1,2} ${CLFS}/boot/grub
+}}}
+
+== Changes to Final-Sysyem section ==
+
+Thid build is only required for the final-system section of the book.
+
+=== Build Grub Legancy ===
+
+The 'make check' is optional.
+
+{{{
+./configure --prefix=/usr
+make
+make check
+make install
+mkdir -pv /boot/grub
+cp -v /usr/lib/grub/*/stage{1,2} /boot/grub
+}}}
+
+
+The FHS stipulates that the bootloader's configuration file should be symlinked to /etc/{Bootloader Name}. The bootloader's configuration file is created in the following section. To satisfy this requirement for GRUB, issue the following command: 
+{{{
+mkdir -v /etc/grub &&
+ln -sv /boot/grub/menu.lst /etc/grub
+}}}
+
+
+== Installing Grub ==
+GRUB uses its own naming structure for drives and partitions in the form of (hdn,m), where n is the hard drive number and m is the partition number, both starting from zero. For example, partition hda1 is (hd0,0) to GRUB and hdb3 is (hd1,2). In contrast to Linux, GRUB does not consider CD-ROM drives to be hard drives. For example, if using a CD on hdb and a second hard drive on hdc, that second hard drive would still be (hd1).
+
+Using the above information, determine the appropriate designator for the root partition (or boot partition, if a separate one is used). For the following example, it is assumed that the root (or separate boot) partition is hda4.
+
+After running the 'grub' command. tell GRUB where to search for its stage{1,2} files. The Tab key can be used everywhere to make GRUB show the alternatives. Install grub to the MBR and then quit.
+
+{{{
+grub
+root (hd0,3)
+setup (hd0)
+quit
+}}}
+
+=== Creating the Boot Menu ===
+
+Create a "Boot Menu" for grub by defining the boot menu, ${CLFS} is only required if you are using the boot method.
+
+{{{
+cat > ${CLFS}/boot/grub/menu.lst << "EOF"
+# Begin /boot/grub/menu.lst
+
+# By default boot the first menu entry.
+default 0
+
+# Allow 30 seconds before booting the default.
+timeout 30
+
+# Use prettier colors.
+color green/black light-green/black
+
+# The first entry is for CLFS.
+title CLFS SVN-20100101
+root (hd0,3)
+kernel /boot/clfskernel-2.6.30.5 root=/dev/hda4
+EOF
+}}}
+
+Add an entry for the host distribution if desired. It might look like this: 
+{{{
+cat >> ${CLFS}/boot/grub/menu.lst << "EOF"
+title Red Hat
+root (hd0,2)
+kernel /boot/kernel-2.6.5 root=/dev/hda3
+initrd /boot/initrd-2.6.5
+EOF
+}}}
+
+
+If dual-booting Windows, the following entry will allow booting it: 
+{{{
+cat >> ${CLFS}/boot/grub/menu.lst << "EOF"
+title Windows
+rootnoverify (hd0,0)
+chainloader +1
+EOF
+}}}
