I am using a Multiboot-environment (BIOS) and I want to configure grub so, that it remembers the last selected entry(OS) for booting next time. Is it all right to add the following entry to /etc/default/grub: GRUB_SAVEDEFAULT=true and afterwards to run sudo grub-mkconfig -o /boot/grub/grub.cfg? Please explain, if that is the right way. THY

Yes, when you want grub to remember the last selected entry as default for the next boot, it is required to add the following line to /etc/default/grub:
