65.052 Moving the Recovery Partition to extend a partition size

Here’s how to correctly move the Windows Recovery Partition on a Windows server or a normal Windows system.
This is what my partitions look like in Disk Management.
We will move the 1 GB recovery partition to the end of the disk allowing us to add the 50 GB of unallocated space to the C drive.
The Process
Make sure you have a backup of the system you are going to edit the partitions on.
Open Command Prompt as admin
Run CMD as admin
Disabling The Windows Recovery Partition
We need to disable the existing Windows Recovery Partition to do that run the command 
reagentc /disable
Disabling the Recovery Partition
The 
reagentc /disable command will disable the recovery partition and will move the recovery partition into a file named 
Winre.wim and will be located in 
C:\Windows\System32\Recovery (you have to enable showing hidden system files if you want to see it)
The Windows Recovery Partition File
DiskPart
Run the command 
diskpart to launch DiskPart
Launching DiskPart
List the disks in your system. You can do this by using the command 
list disk
Listing the disks in DiskPart and showing the disk is a GPT disk
Pro tip from Matt in the comments, if there’s a * in the column for Gpt that means the disk is likely a GPT disk and if there isn’t a * in the Gpt column the disk is likely MBR. Make a note of this as it will be important further down.
Select the disk you need to move the recovery partition on. You can do this by using the command 
select disk and the disk number. In my setup disk 0 was the correct disk and the command I entered was 
select disk 0.
Selecting the disk in DiskPart
List the partitions on that disk. You can do this by using the command 
list partition
Listing the partitions in DiskPart
Select the recovery partition. You can do this by using the command 
select partition and the partition number. In my setup partition 4 is my recovery partition and the command I entered was 
select partition 4
Selecting the partition in DiskPart
The recovery partition is a protected partition so we need to use a bit more force to delete it.
Force the deletion of the recovery partition. You can do this by using the command 
delete partition override
Forcing the partition deletion
Disk Management
Now if you look in Disk Management you should no longer have the Recovery Partition and it should show up as unallocated.
Disk Management with the Recovery Partition deleted
Expand your disk and leave about 1024 MB off your resized size to leave room for the re-enabling the Recovery Partition.
Expanding the partition but leaving room for the Windows Recovery Partition
Disk Management should now look something like this.
Disk Management after expanding the disk and leaving room for the Windows Recovery Partition
Once the disk is expanded we need to rebuild everything that is needed for Windows to know that the extra space that we left unallocated can be used to for the recovery partition.
Create a New Simple Volume with the unallocated space.
Creating a New Simple Volume
Don’t give it a drive letter.
Not giving the New Simple Volume a drive letter or a drive path
You can give the new partition a name if you want it does not mater. I’m going to call mine New Recovery.
Naming the New Simple Volume
Disk Management should now look something like this.

Back to DiskPart
In DiskPart list your partitions again by running the command 
list partition
Listing the partitions with DiskPart
Select the 1024 MB partition with the command 
select partition and the partition number. In my setup it was partition 4 and the command I ran was 
select partition 4
Selecting the partition with DiskPart
If you have a GPT disk you need to run some very specific command and if you have an MBR disk you need to run different very specific commands.
GPT disk
On GPT disks we need to change the partition ID to de94bba4-06d1-4d40-a16a-bfd50179d6ac which tells Windows that this is a recovery partition
Run the following command to set the partition as a recovery partition 
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
Setting the GPT partition ID in DiskPart
We also need to hide the drive and flag it as a required partition to do that we have to set a GPT attribute to 0x8000000000000001
Run the following command to set the GPT attribute to hide the drive and flag it as required 
gpt attributes=0x8000000000000001
Setting the GPT attribute in DiskPart
Now we can exist DiskPart.
Exiting DiskPart
MBR disk
On MBR disks we need to change partition ID to 27 which will tell Windows that this is a recovery partition.
Run the following command to set the partition as a recovery partition 
set id=27
setting the MBR partition ID in DiskPart
Now we can exist DiskPart.
Exiting DiskPart
Enabling The Windows Recovery Partition
Now we can re-enable the recovery partition by running the command 
reagentc /enable
Enabling the Windows Recovery Partition
The 
reagentc /enable command will copy the 
Winre.wim file from 
C:\Windows\System32\Recovery into our new recovery partition.
Windows Recovery Partition file is now back on the recovery partition
If you look at Disk Management again everything shows up correctly.
That’s all there is to it.
