Workaround
If you have upgraded to Windows 8.1 or Windows Server 2012 R2, use one of the following workarounds to work around this issue.
Temporarily disable WinRE when taking a system image backupNote WinRE will be disabled in the backup image. Therefore, you have to enable it after you do a system recovery from this image.
-
Right-click the Start button, and then click Command Prompt (Admin) to open an elevated Command Prompt window.
-
Disable WinRE by running the following command:
reagentc /disable
-
Run the system image backup function.
-
Enable WinRE by running the following command:
reagentc /enable
Manually re-create the WinRE partitionNote Depending on your disk layout, the exact steps may vary.
-
Right-click the Start button, and then click Command Prompt (Admin) to open an elevated Command Prompt window.
-
Disable WinRE by running the following command:
reagentc /disable
-
Start DiskPart by running the following command:
diskpart
-
To obtain summary information about each disk in the computer, run the following commands, and then select a disk:
list diskSelect disk 0
-
From the "list partition" output, find the Recovery partition, and then note the current size of the partition.If there are multiple Recovery partitions, select the one that comes after drive C from Disk Management.DISKPART> list partitionPartition ### Type Size Offset------------- ---------------- ------- -------Partition 1 Recovery 300 MB 1024 KBPartition 2 System 100 MB 301 MBPartition 3 Reserved 128 MB 401 MBPartition 4 Primary 885 GB 529 MB
-
To delete the partition, run the following commands:
select partition 1delete partition override
-
Right-click the Start button, and then click Disk Management.
-
Find the unallocated partition, and reduce the volume before it by 100 megabytes (MB) so that you have a free block that is 100 MB larger than the original recovery partition. If there is no volume before the free block, reduce any volume by 100 MB plus the original Recovery partition size. For example, reduce a volume by 400 MB in the earlier example. For more information about how to shrink a basic volume, go to the following Microsoft TechNet website:
-
Right-click the unallocated partition, and then click New Simple Volume.
-
Continue through the steps in the wizard, using the default settings, to create the new partition.
-
To copy the WinRE image to the partition and enable WinRE, run the following commands:
mkdir G:\Recovery\WindowsRExcopy /h C:\Windows\System32\Recovery\Winre.wim G:\Recovery\WindowsREreagentc /setreimage /path G:\Recovery\WindowsRE /target C:\Windowsreagentc /enabledel /a C:\Windows\System32\Recovery\Winre.wim
Note Inthese commands, it’s assumed that the new partition is assigned the letter G.
-
To remove the drive letter and mark the partition as a recovery partition by using DiskPart, run the following commands:
-
For UEFI systems
select disk 0select partition 1removeset id=de94bba4-06d1-4d40-a16a-bfd50179d6acgpt attributes=0x8000000000000001
-
For BIOS systems
select disk 0select partition 1set id=27remove
-
-
Exit DiskPart.
