if you have normal bios read this post

if you heve uefi bios read this

of course if you have uefi bios you must enable legacy boot option,disable secure boot and in some case fast boot for Windows
to delete Kali partition use windows disk management or some partitions tolls like Minitool partition wizard or similar.
