I installed kali linux along side windows 8 using live usb created using lili usb creator, installed successfully. From the grub menu when i select kali linux it freezes on "loading initial ramdisk...".
My laptop is lenovo g505s AMD-A10 1Tb hdd 8gb ram dual graphics(ATI)

I used nomodeset while booting but no luck.

Searched over internet. Problem seems to be with video mode or graphics driver (not sure) .
