    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.

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