Most, if not all, Linux distro's ask you about this during the installation process. Debian does for sure. Carefully check all that mentions Grub, MBR or bootloader during the installation and make sure these options are unchecked (they are on by default).
After the installation is finished, the newly installed flavor will not yet be visible/accessible when booting. You need to boot into Ubuntu first, run the command given in my previous post (sudo grub-update
), this will pick up the new bootable OS and create an entry for it. Now a third entry is present when you (re)boot.
Hope this helps.
