edit /etc/grub.d/40_custom and add this at the bottom of what is already there, rerun grub-mkconfig
Code:
menuentry 'parabola'{
insmod load_video
set gfxpayload=keep
insmod gzio
insmod part_gpt
insmod ext2
set root=(hd0,5)
search --no-floppy --fs-uuid --set=root 522c8b3d-2472-441b-8961-2809edab6ff1
linux (hd1,5)/boot/vmlinuz-linux-libre-lts root=UUID=522c8b3d-2472-441b-8961-2809edab6ff1 loglevel=3
initrd (hd1,5)/boot/initramfs-linux-libre-lts.img
}
menuentry 'windows' --class=windows{
