I have been working to verify
ariftwister's claims that EaseUS was the cause of the problem, and was able to do so. I installed the Easeus partition manager and made a change to a partition. The two recovery partitions changed to a Type designation of
OEM. After the change I saw a popup message from Easeus about updating the system information, which is more than likely when the problem occurred.
But the problem was a little more involved than just changing a partition ID to the Recovery GUID. On my system, the IDs were already set to the Recovery GUIDs and were not changed when the error occurred.
What it appears happened, was the Easeus utility removed the volume information from the two recovery partitions, as Diskpart noted in the quoted material. Since replacing the Partition ID with the same number was of no help, I ended up changing them to the Primary partition GUID, ebd0a0a2-b9e5-4433-87c0-68b6b72699c7. After a Reboot, the partitions showed up as Type Primary in Diskpart.
I then changed the partitions back to the Recovery GUIDs and the system was back to normal and the
reagentc /info command completed.
Luckily you can copy and paste into, out of, and within a Command Prompt window, those GUID numbers can be a pain to type. :shock:
The attachments might help explain.
