permanent grub2 menu using uck

Question

I am using UCK-remaster to remaster a mini ubuntu 12.10 iso. Now I want to boot a remastered live cd that always shows / displays the grub2 menu. Now It only shows when i press a button. I dont want to press a button to show the menu, it has to boot directly into the grub2 menu!!!!.

I am changing /etc/default/grub.cfg like this:

    sudo uck-remaster-chroot-rootfs

Edit the /etc/default/grub file. Here is my CURRENT grub file (Already tried to # both #GRUB_HIDDEN_TIMEOUT=0 and GRUB_HIDDEN_TIMEOUT_QUIET=true without any luck. Also did update-grub):

    # If you change this file, run 'update-grub' afterwards to update
    # /boot/grub/grub.cfg.
    # For full documentation of the options in this file, see:
    #   info -f grub -n 'Simple configuration'

    GRUB_DEFAULT=0
    #GRUB_HIDDEN_TIMEOUT=0
    GRUB_HIDDEN_TIMEOUT_QUIET=true
    GRUB_TIMEOUT=-1
    GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX=""
    GRUB_DISABLE_OS_PROBER=TRUE

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Thank you
