Hi Shao,
             I copied the contents of /boot minus the syslinux dir to
a temp location, zeroed out /dev/sda8, created ext4 fs in that and
setting up syslinux. After rebooting same "Boot error".

Is there any way to directly load /boot/syslinux/ldlinux.sys from
grub2 instead of the partition bootsector.

Thanks and Regards.
