Fired up a Win7 VM just a couple of minutes ago and ran some Windows Updates (since I hadn't it been using for a while). Then I decided to make a snapshot. (the first Snapshot I did ever on this VM).
Got an error message that some device was busy. So I decided to shut down the machine first. Used ACPI shutdown for this.
Then ran the Snapshot. Don't know whether the Snapshot had terminated at the point I tried to start the machine next time. I didn't see any signs that the snapshot was still running, don't know anyway, whether the snapshot prompts back.
Anyway after I tried to start the machine again, I got the error message as shown in the subject:
FATAL: Could not read from the boot medium! System halted.
What can I do now?

FWIW, I'm adding the recent log excerpt:
