Hello guys I searched everywhere for my exact issue nothing has helped at all.

I have the latest Kali and Virtualbox.

I looked up many videos setting them up and followed exactly what they did and I still black screen.

I have a windows 7 (if that matters?)

Exact issue: I set up everything, start the machine, select graphical install or normal install then black screens. No text, nothing. Just straight up black screen!
NOTE: I also noticed my Debian only shows 32 bit but the videos select 64 bit? I also looked it up they said go in bios and select 64 bit but I went in bios and have nothing about changing my bit or anything. like all i can do is change my time, put password and nothing much to it :C
