Kali Linux Black Screen

Hi I am new to the community and really need some help.

I recently tried booting my kali linux usb in my new laptop ,I choose the Live(failsafe) option at the boot menu. It started booting but suddenly hangs after the boot only a black-grey screen shown I checked the checksum and it was correct, tried it with virtualbox also same result. During the boot process it hangs for a few second with a "(EDD=off to disable).

I'm using a asus UB-R4074T

it has Nvidia GT940m and 8gb of ram. I also tried booting into the grub menu by trying the shift key but only end up in the screen asking for my disk image. I suspect is the graphic card causing the screen display to split.MOST IMORTANTLY can anyone tell me how to boot into the grub menu. thanks in advance
