Setting WinRE (Windows Recovery Environment) Flag On Partitions

• Run diskpart
• Make sure of the correct disk number by running list disk command.
• Run select disk X where X is the number of cloned disk.
• Make sure of the correct WinRE partition(s) number by running list partition command.
• select partition Y where Y is the number of WinRE partition.

• Run set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac" to set Recovery Flag on the partition.

  (Optional): to provide more protection on partition Run gpt attributes=0x8000000000000001. This attribute is cumulative and the sum of 0x0000000000000001 (set as required partition by system) and 0x8000000000000000 (prevent assigning drive letter automatically on new machines).

• Repeat last 2 steps for each of the additional WinRE partitions.

Note: Just for your consideration, you can also do this on MBR disks by running set id=27.

Update:

If you've accidentally set Recovery Partition ID (or any other ID) on a partition by mistake, to convert it to a normal partition again:

On an MBR Disk:

select disk X
select partition Y
set id=7

On a GPT Disk:

select disk X
select partition Y
set id="ebd0a0a2-b9e5-4433-87c0-68b6b72699c7"

Where 0x07 and ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 are partition type IDs for normal partitions respectively on MBR and GPT disks. (You can find it as the first item in the last link called PARTITION_BASIC_DATA_GUID. also for MBR see 3rd link).
