Did you mean the /boot/grub2/grub.cfg file? If so, your edit will be
wiped clean when grub2-mkconfig is run next time (kernel update etc).

To modify grub.cfg, you'd need to create a file in /etc/grub.d/ (for
example, 11_Windows7):

#! /bin/bash
echo "Adding Windows7"
cat << EOF
menuentry "Windows7" {
set root=hd0(1,2)
chainloader +1
}
EOF

Make the file executable and then run:

grub2-mkconfig -o /boot/grub2/grub.cfg
