-<para>(To be filled in)</para>
+<para>Now that we have our shiny new LinuxFromScratch system completed,
+we need to ensure we can boot it.  To do this, we will run the grub program.</para>
+
+<para><screen><userinput>grub</userinput></screen></para>
+
+<para>Grub uses it's own naming structure for drives, in the form of hd(a,b),
+where a is the hard drive number, and b is the partition number, both of which
+start from zero.  So, partition hda1 would be hd(0,0) to grub, and hdb2 would
+be hd(1,2).  Also, Grub doesn't pay attention to CDROM drives at all, so if,
+for example, if you have a CD on hdb, and a second hard drive on hdc, partitions
+on that second hard drive would still be hd(1,b).</para>
+
+<para>So, using the information above, select the appropriate designator for
+your root partition.  For the purposes of this, we will assume hd(0,3) for
+your root partition.  First, we tell grub where to find it's files:</para>
+
+<para><screen><userinput>root (hd0,3)
+setup (hd0)
+quit</userinput></screen></para>
+
+<para>This tells grub to look for it's files on hda4 (hd0,3), and install itself
+into the MBR (Master Boot Record) of hda.</para>
+
+<para>Also, we need to create the <filename>menu.lst</filename> file, which
+Grub uses to designate it's boot menu:</para>
+
+<para><screen><userinput>cat > /boot/grub/menu.lst << "EOF"
+# Begin /boot/grub/menu.lst
+
+# Default to first menu entry
+default 0
+
+# Allow 30 seconds before booting default
+timeout 30
+
+# Use prettier colors
+color green/black light-green/black
+
+# Default Entry for LFS
+title LFS 5.0
+kernel (hd0,3)/boot/lfskernel root=/dev/hda4 ro
+EOF</userinput></screen></para>
+
+<para>You might also want to add in an entry for your host distribution.  It
+might look similar to this:</para>
+
+<para><screen><userinput>cat >> /boot/grub/menu.lst << "EOF"
+# Redhat Linux
+title Redhat
+kernel (hd0,2)/boot/kernel-2.4.20 root=/dev/hda3 ro
+initrd (hd0,2)/boot/initrd-2.4.20
+EOF</userinput></screen></para>
+
+<para>Also, if you happen to dual-boot Windows, the following entry should
+allow booting it:</para>
+
+<para><screen><userinput>cat >> /boot/grub/menu.lst << "EOF"
+# Windows
+chainloader (hd0,0)+1
+EOF</userinput></screen></para>
+
+<para>You can find more info regarding Grub on it's web site, located at:
+<ulink url="http://www.gnu.org/software/grub"/>, as well as the LFS Grub HOWTO
+located at: <ulink url="http://www.linuxfromscratch.org/hints/downloads/files/grub-howto.txt"/>.</para>
