If you find that update-grub is applying the desired changes to grub.cfg but you don't see those changes at the GRUB boot prompt then GRUB (Debian) may not be updating the relevant area. Compare the actual boot choices you see to both Ubuntu's grub.cfg and Debian's $ grep menuentry /boot/grub/grub.cfg You don't say 'what' is bootable - mbr, partition/s etc. If Ubuntu and Debian are using different types of schemes it can cause (fixable) problems. It may be as simple as mounting the Ubuntu slice and copying the relevant section from it's /etc/grub.d/* to the same in Debian and re-running upgrade-grub.
