In reference to the manual, this is what I have come up with:

title Install Fedora 19

    repo=/iso_fedora_19

    findiso

    kernel isolinux/vmlinuz root=/dev/sdb12 quiet

    initrd isolinux/initrd.img

title Install Fedora 19 loopback {

    root (hd1,12)

    loopback loop /iso_fedora_19/Fedora-19-i386-DVD.iso

    linux (loop)/isolinux/vmlinuz root=/dev/sdb12 quiet

    initrd (loop)/isolinux/initrd.img

}

I found a way to make it work.

1) I found that there is a version of grub2 in Fedora 14. I installed grub2 with the following command:

    yum -y install grub2

2) To the file "/etc/grub.d/40_custom", I added the following entry:

    menuentry 'Fedora Linux 19 Install ks=hd:sdb3:/ks.cfg.fc19 repo' {
            set root=(hd1,12)
            linux /iso_fedora_19/isolinux/vmlinuz ks=hd:sdb3:/ks.cfg.fc19 repo=hd:/dev/sdb12:/iso_fedora_19/
            initrd /iso_fedora_19/isolinux/initrd.img
    }

3) In the directory "/mnt/sdb12/iso_fedora_19/", is the following:

    /mnt/sdb12/iso_fedora_19/
    /mnt/sdb12/iso_fedora_19/Fedora-19-i386-CHECKSUM
    /mnt/sdb12/iso_fedora_19/Fedora-19-i386-DVD.iso
    /mnt/sdb12/iso_fedora_19/images
    /mnt/sdb12/iso_fedora_19/images/pxeboot
    /mnt/sdb12/iso_fedora_19/images/pxeboot/initrd.img

    /mnt/sdb12/iso_fedora_19/isolinux/vesamenu.c32
    /mnt/sdb12/iso_fedora_19/isolinux/vmlinuz

4) I executed the following commands:

    grub2-mkconfig -o /boot/grub2/grub.cfg
    grub2-install /dev/sda

5) Reboot the system and choose the install entry:

    Fedora Linux 19 Install ks=hd:sdb3:/ks.cfg.fc19 repo

6) One problem I found was that the Fedora 19 install did not update /dev/sda to use the file "/boot/grub2/.grub.cfg". It still booted using the "grub.cfg" from the Fedora 14 system.

So I had to repeat these two commands:

    grub2-mkconfig -o /boot/grub2/grub.cfg
    grub2-install /dev/sda
