Cannot install guest from ISO image on Ubuntu host

[Elastic]

Host: Ubuntu 14.04
VirtualBox 4.3.34

Guest OSs I have tried:
Linux Fedora 23 64-bit Live ISO image
Linux Fedora 23 32-bit Live ISO image
Linux Mint 17.3 64-bit Live ISO image
Linux Debian 8.2 64-bit Live ISO image

Description:
I am attempting to install a Linux guest but am encountering the same problem with several different Linux images. I use the default settings suggested by VirtualBox when creating the VM.

When I start the VM, I select an ISO image from a local harddrive. The guest OS ISO image then boots, and displays a list of boot options ("Install", "Test this image" etc). These are options provided by the guest ISO bootloader. I then select any option. The size of the VM window then may change and always turns all-black. A few seconds pass and the window then closes. Status in VirtualBox UI is that the VM "Aborted". I attached my VBox.log.

This problem occurs regardless of which ISO image above I select, suggesting the problem has more to do with my VirtualBox installation rather than the ISO images or guest OSs.

I am currently successfully running a Windows host plus a Ubuntu guest (created by vagrant) with my VirtualBox installation. I have turned these VMs off before attempting to boot any of the ISO images.

Any advice how to troubleshoot this very much appreciated!

You are using the Ubuntu fork and as such will need to seek their assistance. If you want us to help you would need to remove theirs and install the official version from virtualbox.org

PS: We don't support any version where vagrant is involved.
