Oracle virtual box inaccessible

This normally happens if the host OS crashes or you pull the plug on it, leaving the .vbox file unsaved.

In the location:

C:\Users\xxxxxxx\VirtualBox VMs\vBoxxxxXubuntu_Beta\

you should find two files:

  1. vBoxxxxXubuntu_Beta.vbox-prev
  2. vBoxxxxXubuntu_Beta.vbox-tmp

Copy vBoxxxxXubuntu_Beta.vbox-prev to vBoxxxxXubuntu_Beta.vbox.

Select vBoxxxxXubuntu_Beta.vbox, in the VBox manager, right click, and then left click on refresh.

Observe that it now shows Powered Off.

Now you are good to go.
