Lenovo ALL-IN-ONE dual booting Win10 and Linux (Zorin). It defaults booting to Windows. First I edited the grub flie to make Zorin first and updated the grub file. It seems to ignore that, and still requires pressing F12 at a very precise time to get to the boot choices, I think EFI is doing something.
So, I tried deleting all of the Windows's partitions and updating the grub file. Now it still tries to boot and find Windows that is not there, requiring the F12 process.
I guess I could totally reinstall Zorin, but is there a way to kill -9 windows?
