[SOLVED]Removed Syslinux by Accident Cannot Setup Dual Boot Win8/Arch

by accident I removed initial sector and could not boot neither system. Now I`ve setup a grub where I can at least boot windows. I still have the config files from syslinux in:
/dev/sdb5

Grub and Syslinux are there. Before the removal I was using syslinux.

Syslinux.conf holds the following contents:

    # Config file for Syslinux -
    # /boot/syslinux/syslinux.cfg
    #
    # Comboot modules:
    #   * menu.c32 - provides a text menu
    #   * vesamenu.c32 - provides a graphical menu
    #   * chain.c32 - chainload MBRs, partition boot sectors, Windows bootloaders
    #   * hdt.c32 - hardware detection tool
    #   * reboot.c32 - reboots the system
    #   * poweroff.com - shutdown the system
    #
    # To Use: Copy the respective files from /usr/lib/syslinux to /boot/syslinux.
    # If /usr and /boot are on the same file system, symlink the files instead
    # of copying them.
    #
    # If you do not use a menu, a 'boot:' prompt will be shown and the system
    # will boot automatically after 5 seconds.
    #
    # Please review the wiki: https://wiki.archlinux.org/index.php/Syslinux
    # The wiki provides further configuration examples
    
    DEFAULT arch
    PROMPT 0        # Set to 1 if you always want to display the boot: prompt 
    TIMEOUT 50
    # You can create syslinux keymaps with the keytab-lilo tool
    #KBDMAP de.ktl
    
    # Menu Configuration
    # Either menu.c32 or vesamenu32.c32 must be copied to /boot/syslinux 
    UI menu.c32
    #UI vesamenu.c32
    
    # Refer to http://syslinux.zytor.com/wiki/index.php/Doc/menu

Arch is located at /dev/sdb3
I would like to recover it. Is it possible? At the momment. I have grub able to boot windows. Can I make the transition back to my old syslinux? If so how should I proceed?

I also have grub in /dev/sdb3 where arch is located. How do I set /dev/sdb5 back to the "default" loader?

UPDATE:
Fixed with help of people in #arch at freenode.

All I had to to was to run syslinux-install_update -iam /dev/sdb and it did rewrite my mbr.
