volume does not show recovery and restore volumes
partition shows recovery and restore as OEM.

Further reagentc /info and reagentc /enable shows
Reagentc.exe operation failed: 3
Reagentc.exe An error has occurred.

My machine is reserved for windows 10.
Does this has anything to do with above changes?
Why this happens?

I want to clean install windows 8.1 before upgrading to windows 10 so that all junk is removed. Am I doing right?
How should I go about?

Your recovery partitions have had their GPT attributes modified. Nothing to worry about.

If it bothers you, remove the "required" attribute from the partitions.

No attribute : 0x0000000000000000
"Required" aka "OEM" : 0x0000000000000001
No drive letter : 0x8000000000000000
Hidden : 0x4000000000000000
Shadow Copy : 0x2000000000000000
Read Only : 0x1000000000000000


You assign them in diskpart like this:

[CODE[
sel dis 0
sel par 2
gpt attributes=0xD000000000000000
sel par 12
gpt attributes=0xD000000000000000
exit
[/CODE[

That will remove the OEM attribute, and apply hidden, no drive letter, and readonly.

Thanks hydranix.
This changes partition type as unknown. Is there anyway to change original Recovery.

set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
gpt attributes=0x8000000000000001

Thanks. I was not sure about id and hence delay.
