I am using Oracle Virtual Box version 4.2.16 r86992. Everything was fine until yesterday shutdown. Today, it shows inaccessible and throws this error:
Runtime error opening C:\Users\xxxxxx\VirtualBox VMs\vBoxxxxXubuntu_Beta\vBoxxxxXubuntu_Beta.vbox for reading: -102 (File not found.).
D:\tinderbox\win-4.2\src\VBox\Main\src-server\MachineImpl.cpp[725] (long __cdecl Machine::registeredInit(void)).
It's good to restore this to working, It would save lot of time and restore configuration settings and data. Thanking your support.
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:
vBoxxxxXubuntu_Beta.vbox-prev
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.
