How to separate boot menu windows and kali?

Question

Windows

There are two operating systems, but there is only one in the boot menu. How to separate them? I do not want him to ask every time he reboots, kali or windows. How to put windows first?

Answer 1

1. Install Windows
2. Install Kali
3. Edit the GRUB bootloader so that the default system is windows. If you do not violate the installation order of operating systems, the Linux bootloader will see windows itself.
Also in GRUB, you can change the time before the OS boots by default.
