Trying to run Kali Linux on virtual box.

[Mowblow]

I have set up and connected my Kali Linux ISO to the virtual machine, but when I click start, it gives me an error. There error is as follows:
Failed to open a session for the virtual machine "Kali"

The virtual machine 'Kali' has terminated unexpectedly during startup with exit code 1



Result Code:
E_FAIL (0x80004005)

Component:
Machine

Interface:
IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

Maybe I did this wrong, can anyone help?
