I will show you 4 methods to repair or to restore the WinRE environment in Windows 10, however, the procedure is the same for Windows 7 and Windows 8.1.
Method number 1:
Type CMD into Search box, then run command prompt as administrator
If you are booting from USB, open command prompt and Execute this command to identify windows partition:
BCDEDIT
Execute this command to change CMD directory to System 32 folder.
CD /D C:WINDOWSSYSTEM32
Execute the following command to show of windows identifier:
BCDEDIT /V /ENUM OSLOADER
Type this command without hitting Enter:
REAGENTC /ENABLE /OSGUID
Copy the identifier of windows and paste it after previous command then press Enter.
Make sure the description is containing Windows 10 or the windows version that is installed on your PC.
In running windows, you can execute Reagentc command with or without using OSGUID.
Method number 2:
Search for WinRe.wim image file using this command:
DIR /S /A C:WINRE.WIM
If the file found in another folder, copy it into recovery folder using this command:
XCOPY /H C:RE_BACKWINRE.WIM C:WINDOWSSYSTEM32RECOVERY
Execute Reagentc Command again to enable Recovery.
Method number 3:
Type DISKPART and hit enter
Type LIST DISK and hit enter
SEL DISK 0
Execute this command to show the list of volumes:
LIST VOL
Execute this command to show the list of partitions:
LIST PART
Recovery partition usually labelled with Recovery name and its size around 500 megabytes with NTFS file system, but not FAT32 file system.
In a custom manufacturer recovery with additional apps or tools, the size of partition may extended into many gigabytes.
If the recovery volume doesn’t have a letter, give it V letter using the following 2 commands:
SEL VOL 2
ASSIGN LETTER=V
Execute EXIT command to close DISKPART
Show contents of the V partition using this command:
DIR /S /A V:
XCOPY /H V:RECOVERYWindowsREWINRE.WIM C:WINDOWSSYSTEM32RECOVERY
ATTRIB -S -H -R V:RECOVERYWINDOWSRE*.*
Delete all files in WindowsRE folder using this command:
del V:RECOVERYWINDOWSRE*.*
In running windows, you may need to set the recovery path using this command:
REAGENTC /SETREIMAGE /PATH C:WINDOWSSYSTEM32RECOVERY
Rename the Ragent.xml file in recovery folder using this command:
REN C:WINDOWSSYSTEM32RECOVERYREAGENT.XML REAGENT.OLD
Enable recovery Environment using ReagentC command as on method number 1.
If the reagentc failed with this error message, “The boot configuration data has not been configured” or “REAGENTC.EXE: Unable to update Boot Configuration Data”, you can fix that as followings:
execute the following command to rebuild BCD,
BCDBOOT C:WINOWS
Method number 4: How to enable Recovery if the required files are missing?
If the WinRE.wim file is not available in windows or recovery partition, you have to copy it from ISO file of windows installation with the same or newer build number then installed windows.
In running windows,
Double click the ISO file to mount it and memorize its letter.
When booting from a USB, open Notepad:
Click on file tab then select Open option
Click on this PC icon to show all partitions
Determine the letter of the USB drive
In my system, the D partition is assigned to USB partition.
Extract the first index from Install.wim file using this command:
MD C:MOUNT
DISM /MOUNT-IMAGE /IMAGEFILE:D:SOURCESINSTALL.WIM /INDEX:1 /MOUNTDIR:C:MOUNT /READONLY
Copy the WinRE.wim:
XCOPY /H C:MOUNTWINDOWSSYSTEM32RECOVERYWINRE.WIM C:WINDOWSSYSTEM32RECOVERY
I have already created a bootable recovery image for windows 10 X64 version 19041.
XCOPY /H E:SOURCESBOOT.WIM C:WINDOWSSYSTEM32RECOVERY
Replace the E with the letter of the USB drive or the mounted ISO file in your computer.
Rename the boot.wim file to Winre.wim:
REN C:WINDOWSSYSTEM32RECOVERYBOOT.WIM WINRE.WIM
Finally execute the Reagentc command again to enable Recovery.
