VBox error on Fedora 25 [x64bit]

[Raze22]

Hi,

For reference, I am running Fedora 25 (64 bit version). I managed to successfully install VBox. I then set up a Linux, Debian (64-bit) with the intention of running Kali on it.

However, once I click "start" to launch the VM, I get the following error code:

Failed to open a session for the virtual machine Kali Playground2.

The virtual machine 'Kali Playground2' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

Screenshot included. I know the screenshot gives me a command to run, but before I started doing things out of my depth, I wanted to gain some insight/feedback.

Any help is welcomed!

Looks very similar to my problem a few days ago: viewtopic.php?f=7&t=81591
Make sure that Secure Boot is not enabled in the system BIOS.
