Could not find an open hard disk with UUID {XXX}. Julien V. "I've created a new snapshot, then deleted previous snapshot, so VirtualBox merged the snapshots during a while. When I came back some time after and tried to run my virtual machine, it was set as Inaccessible, following message was displayed: A differencing image of snapshot {acd6ad3e-6a80-4d5a-9ae1-bb535c0eca31} could not be found. Could not find an open hard disk with UUID {e3615b79-4c5a-4621-bd61-b2fe9424520f}. Result Code: E_FAIL (0x80004005) Component: SnapshotMachine Interface: IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91} So I cannot use my virtual machine anymore.
