After booting into wubuntu (it is Windows Ubuntu, formerly known as WindowsFx or LinuxFx) I used grub-customizer to update grub. What changes to /etc/default/grub were you thinking of? I have the impression that grub-customizer makes the required changes.
Edit: Here's my /boot/grub/grub.cfg As you can see dsl is there but if I choose it i get a error sauing "<You need to load the kernel first"
