Installation • [solved] GRUB: cannot modify boot sequence

Yesterday, I've added Debian from a current Live-System to a Lenovo Yoga Laptop. By default, GRUB now starts Debian - I need to set the pre-installed Windows as default, instead.

I have modified /etc/default/grub according to the Debian-Wiki. Trying to apply the changes (as root) using update-grub fails with the error-messageWhat's wrong?

Update: problem solved in German forum:

use

Code:

su -

to become root.
The minus sign makes the difference.
