This is not the first time to install Kali on my machine (Lenovo Z570), this time , no matter what i do grub refuses to work , i have windows 7 next to Kali , i use a separate boot partiiton and from inside windows with easy bcd , i make Kali bootable ,sometime ago i changed kali to debian ,did the same procedure but ran into the same trouble that was resolved only by using an unofficial debian installation , now i wanna go back to kali , i tried with the 1.1 kali version same thing happened , so i downloaded the new Kali 2 , and again , i install Kali like i always does , choose a separate boot partition , separate home and separate root (makes distrohopping much more pleasant ) ...this time , no matter what i do , i can't boot into my newly installed system , and if i am able to load the kernel and intird file , the system goes into kernel panic .....so any ideas on how to resolve the matter ?
