I have both Ubuntu and Windows installed on my computer.
On my previous Ubuntu install turning the computer on by pressing the normal power-on button would boot the system directly to Ubuntu (grub_timeout was set to 0).
Turning the computer on pressing the Assist button would boot directly to Windows.
After removing and reinstalling Ubuntu the Assist button no longer boots to Windows. Where and how can I configure the system to boot a specific OS depending on the power-on button?
