How to Dual Boot Window 7 and Kali Linux 1.1.0

Hello guys, I'm newbie for using kali linux 1.1.0. I have tried to dual boot Window 10 and Kali Sana 2.0 and i succeed with it. But when i try to dual boot Window 7 with kali linux 1.1.0, i cant make it. I have install Kali linux 1.1.0 same way as i install Kali Sana 2.0, but after finish partition for kali linux, i received this message "no efi partition found". I ignore the message and continue with installation. Once finish , my pc boot directly to window and does not enter grub boot. Need your help guys. Thanks
