+These changes apply if you are using the boot method.

+These changes apply to the final-system section of the book.
+
+=== Building Grub2 ===
+The 'make check' is optional.
+{{{
+./configure --prefix=/usr
+make
+make check
+make install
+}}}
+
+
+== Installing Grub2 ==
+To install Grub2 onto the MBR you need to run the following command. Rember to substitute 'sda' for your boot hard drive.
+{{{
+grub-install /dev/sda
+}}}
+
+== Creating the Boot Menu ==
+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). 
+
+Create a "Boot Menu" for grub by defining the boot menu, ${CLFS} is only required if you are using the boot method. The menu below uses the second partition on the first hard drive, (hd0,1), remember to substitute this for your hard drive and parition.
+{{{
+cat > ${CLFS}/boot/grub/grub.cfg << "EOF"
+# Begin /boot/grub/grub.cfg
+
+set default=0
+set timeout=5
+
+set root=(hd0,1)
+menuentry "Linux 2.6.31.5" {
+  linux /kernel-2.6.31.5 root=/dev/sda2
+}
+
+EOF
+}}}
+
+
+
+If dual-booting with Windows, then following entry will allow booting it:
+{{{
+cat >> ${CLFS}/boot/grub/grub.cfg << "EOF"
+menuentry "Microsoft Windows" {
+        set root=(hd1,1)
+        devicemap -s hd0 hd1
+        chainloader +1
+}
+EOF
+}}}
