Why there is need to install EasyBCD? EasyBCD has messed up something with your boot. The better way is switch to UEFI again and reinstall Windows 10 and kali. You have latest generation PC and you are trying to go back in earlier times when there was no UEFI. Your problem is a result of this action.
