Windows 10: REagentC went mad

I want to set up recovery image location for Windows to custom partion but REagentC went mad.


1. Query info


C:\windows\system32>reagentc /info


Windows Recovery Environment Windows RE and system reset configuration

Information:


Windows RE status: Disabled

Windows RE location:

REAGENTC.EXE: Operation Successful.


2. Enable agent


C:\windows\system32>reagentc /enable

REAGENTC.EXE: Operation Successful.


3. Disable agent


C:\windows\system32>reagentc /disable

REAGENTC.EXE: Windows RE is already disabled.


4. Enable agent again


C:\windows\system32>reagentc /enable

REAGENTC.EXE: Operation Successful.


5. Query info again


C:\windows\system32>reagentc /info


Windows Recovery Environment Windows RE and system reset configuration

Information:


Windows RE status: Disabled

Previously agent had problems writing to BCD – “REAGENTC.EXE:Unable to update Boot Configuration Data.”– that was worked around by specifying the BCD guid using/osguid parameter.

ReagentC "operation failed: 32"

Hello.

What, exactly, does "operation failed: 32" mean when it comes from ReagentC?

Is their a published list of all of the ReagentC failure numbers, and what they mean or what triggers them?

 

Reagentc failed

Empty recovery image location string. Setting image path before winre enabling needed.
perform these steps:

1. set drive letter to recovery partition
2. reagentc /setreimage /path F:\Recovery\WindowsRE
...winre.wim registration (use proper drive letter)
3. reagentc /enable
...winre activating
4. remove drive letter from recovery partition

Can't enable Windows Recovery Environment

 

How does Windows boot to advanced recovery option e.g. command prompt?

- that gives me a 454 'Unexpected error' This tells me that the BCD is partially corrupted.

The commands: shutdown.exe /r /o /f /t 00
or: %SystemRoot%\System32\Cmd.exe /c reagentc /boottore&shutdown /r /f /t 00
should boot into Recovery if everything is configured correctly.
FYI, If Windows is configured correctly:

1. If Reagentc is disabled, you still can get into Recovery but with limited options.
2. If Reagentc is enabled, you'll get all options.
3. If you boot Windows using Recovery USB stick, You'll get into Recovery with couple of options missing.

Here's my suggestion if you want to try:
OPTION 1: Will save the trouble of re-install Windows.

1. Download the image of my first 3 partitions (450MB Recovery, 100 MB EFI partition, and 16MB unformatted primary)
   EFI_Boot-00-00.7z - Google Drive
2. Run Macrium and restore the image from step 1, overwriting your existing 1st three partitions, leaving C alone.
3. Delete the 490MB Recovery partition.
4. From Macrium, run fix boot problems.
5. Reboot. Open Admin command prompt then run Reagentc /info to make sure that it is enabled. If not, enable it.
   if failed to enable, reboot and try again.

OPTION 2: Assuming you've already had Windows backup with Macrium.

1. Wipe out the first 5 parttiions. (450MB, 100MB, 16MB, C Drive, 480MB)
2. Fresh install Windows 10
3. Restore C drive from backup image, run fix boot problems
4. repeat step 5 from OPTION 1 above.
