The procedure involves writing some -special Grub files to specific locations on the hard drive. We highly -recommend creating a Grub boot floppy diskette as a backup. Insert a -blank floppy diskette and run the following commands:</para> - -<screen><userinput>dd if=/boot/grub/stage1 of=/dev/fd0 bs=512 count=1 -dd if=/boot/grub/stage2 of=/dev/fd0 bs=512 seek=1</userinput></screen> - -<para>Remove the diskette and store it somewhere safe.

For example, partition <filename -class="partition">hda1</filename> is <emphasis>(hd0,0)</emphasis> to -Grub and <filename class="partition">hdb3</filename> is -<emphasis>(hd1,2)</emphasis>. In contrast to Linux, Grub does not -consider CD-ROM drives to be hard drives.
