grub2 has 2 operating systems
After my installation of Debian on the 2nd Sda2 partition, has decorated the newly installed operating system grub2 own menu, and then in it since Debian is also at the top to start at boot automatically. This is annoying if you just want to try Debian first and usually just want to boot with Ubuntu. If you look then - like me - do not dare turn to edit the config files of grub2, you have certainly no chance. - - - I thought, is not true!
I boot Ubuntu is enough and then a command to return to the old grub2 of Ubuntu:
$ sudo grub-install / dev / sda
[sudo] password for anyuser:
Installation finished. No error reported.
$ and another command is needed to allow write in all existing operating systems into the options menu (so too does the Ubuntu grub-missing Debian and all existing versions of the kernel):
$ sudo update-grub

$ A great automatic grub2 in helping people who (like me) have neither the desire to tinker idea of grub2 have. Here, again helped me by the way the super great
forum.ubuntuusers.de , which I can not thank you enough. :-)
