    Windows has the wrong location for the recovery partition


    I recently deleted the 2 OEM recovery partitions on the SSD on my laptop (now running version 1909), moved the Windows recovery partition to the end of the disk, and extended my C: drive to take up the newly vacated space. However, now the recovery partition is no longer labelled as a recovery partition in Disk Management. And when I type reagentc /info at the command prompt I get the following:
    Windows Recovery Environment (Windows RE) and system reset configurationInformation: Windows RE status: Enabled Windows RE location: \\?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE Boot Configuration Data (BCD) identifier: 16f70634-8e2e-11e9-a0cb-8f79f51c2075 Recovery image location: Recovery image index: 0 Custom image location: Custom image index: 0REAGENTC.EXE: Operation Successful.

    It says that the recovery partition is partition 4, but I only have three partitions on the disk: the EFI system partition, C:, and the one at the end that ought to be the recovery partition, but seems no longer to be. How do I restore the recovery partition and get Windows to know its new location? I've got as far as extracting a winre.wim file from Windows install media, so I just need to know the steps after that.

    There are 4 partitions on the disk. After the EFI system partition the is a tiny Microsoft System Reserved (MSR) partition that will not show up in disk management. It will if you list partition in diskpart:

    Code:

    DISKPART> select disk 0
    
    Disk 0 is now the selected disk.

    Oh, I see. I was confused by the fact that Disk Management doesn't say that it is a recovery partition, whereas it correctly identifies the recovery partition on my other computer. Is there a reason for this?

    It's just a volume label. It won't hurt that it isn't there.

    For confirmation you can view the 16 MB hidden reserved partition using MiniTool partition wizard:

    Partition layout

    The default partition layout for UEFI-based PCs is: a system partition, an MSR, a Windows partition, and a recovery tools partition.

    Or just use the built in diskpart commands.
