virtualbox - Oracle virtual box inaccessible -

-

i using oracle virtual box version 4.2.16 r86992. fine until yesterday shutdown. today, shows inaccessible , throws error:

runtime error opening c:\users\xxxxxx\virtualbox vms\vboxxxxxubuntu_beta\vboxxxxxubuntu_beta.vbox 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 restore working, save lot of time , restore configuration settings , data. thanking support.

this happens if host os crashes or pull plug on it, leaving .vbox file unsaved.

in location: 

c:\users\xxxxxxx\virtualbox vms\vboxxxxxubuntu_beta\

you should find 2 files:

  1. vboxxxxxubuntu_beta.vbox-prev
  2. vboxxxxxubuntu_beta.vbox-tmp

copy vboxxxxxubuntu_beta.vbox-prev vboxxxxxubuntu_beta.vbox.

select vboxxxxxubuntu_beta.vbox, in vbox manager, right click, , left click on refresh.

observe shows powered off.

now go.
