[syslinux] Replace grub with extlinux

[Face]

Hello all,

I am trying to replace grub with extlinux without any luck. I did
remove the grub from my root Partition and boot from a LiveCD. I
install syslinux and did those steps

    Boot Partition:
        mkdir -pv /mnt/sda1
        mke2fs -jv /dev/hda1
        mkfs -t ext3 /dev/hda1
        mount /dev/hda1 /mnt/sda1

    Root Partition
        export SDB1=/mnt/sdb1
        mkdir -pv $SDB1
        mount -v -t ext3 /dev/hdb1 $SDB1

    SWAP Partition
        /sbin/swapon -v /dev/hdb5

    Installing extlinux to /dev/sda1
        dd if=/dev/zero of=/dev/sda bs=446 count=1
        dd if=/mnt/sdb1/usr/share/syslinux/mbr.bin of=/dev/sda
        install -d /mnt/sda1/boot
        /sbin/extlinux --install /mnt/sda1/boot

    Writing extlinux.conf file
       export  ExtlinuxConf=/mnt/sda1/boot/extlinux.conf
       echo "DEFAULT AlDimnaOS" > $ExtlinuxConf
       echo "LABEL AlDimnaOS" >> $ExtlinuxConf
       echo "	KERNEL /boot/vmlinux-2.6.34-AlDimnaOS-0.0.0.1" >> $ExtlinuxConf
       echo " 	APPEND initrd=/boot/vmlinux-2.6.34-AlDimnaOS-0.0.0.1
root=/dev/sdb1 ro quiet splash" >> $ExtlinuxConf
       echo "	TIMEOUT 100" >> $ExtlinuxConf
       echo "	PROMPT 1" >> $ExtlinuxConf

Copy vmlinux to boot Partition
    cp /mnt/sdb1/boot.old/vmlinux-2.6.34 \
			/mnt/sda1/boot/vmlinux-2.6.34


any help would be greatly appreciated
