I have installed BackTrack 5 (I am posting this here because the BackTrack forums suck), and I have set GRUB up:

root (hd1,4)
setup (hd1)
However, the GRUB prompt appears at boot instead of the GRUB menu. However, when I boot from the Live USB, the GRUB menu works fine. Here are the contents of the grub.cfg:

#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#

if [ -s $prefix/grubenv ]; then
load_env
fi
set default="0"
if [ ${prev_saved_entry} ]; then
set saved_entry=${prev_saved_entry}
save_env saved_entry
set prev_saved_entry=
save_env prev_saved_entry
set boot_once=true
fi

function savedefault {
if [ -z ${boot_once} ]; then
saved_entry=${chosen}
save_env saved_entry
fi
}

function recordfail {
set recordfail=1
if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi
}

insmod gettext
if [ ${recordfail} = 1 ]; then

The reason I want the GRUB menu to show up of because I would like to dual-boot BackTrack 5 with Windows 7.

Any help would be greatly appreciated.

If you can boot into your system reinstall grub2's boot loader to the MBR.

#reinstall from working (not liveCD) system - first find Ubuntu drive:
sudo fdisk -l
#if it's "/dev/sda" then just run:
sudo grub-install /dev/sda
#If that returns any errors run:
sudo grub-install --recheck /dev/sda
sudo update-grub
