Hi,

I had VirtualBox installed happily on an Ubuntu system. Then, the power went out. Now, when I start VirtualBox, it no machines are listed. It gives me the standard:

"The left part of this window is intended to display a list of all virtual machines on your computer. The list is empty now because you haven't created any virtual machines yet."

However, my .vdi is still there. If I go to File->Virtual Disk Manager, it's listed. The location, Disk Type (Normal) and Storage Type (Virtual Disk Image) all look correct. Attached to and Snapshot are both blank (--).

How can I make things work again? I tried making a copy of the .vdi file and then adding it via the Virtual Disk Manager, but it complains that "a hard disk with UUID <whatever> and the same properties <path to .vdi> is already registered."

Thanks in advance.

VirtualBox requires two components to run:
1. A guest machine; and
2. A guest hard disk

It sounds like you still have your guest hard disks but you lost your guest machine(s) in the power outage.

So just create a new guest machine (see big NEW button at top left in VirtualBox), then attach one of your existing hard disks to the new machine, then start the new machine.

If your guest system is Windows and you run into bluescreen on startup, it may need a simple tweak to the machine settings (set IDE Controller to PIIX3).

Thank you sir!
