Windows 10: reagentc confusion...

Can someone explain this behavior?C:\Windows\System32>reagentc /enable REAGENTC.EXE: Operation Successful. C:\Windows\System32>reagentc /info Windows Recovery Environment Windows RE and system reset configuration Information: Windows RE status: Disabled Windows RE location: Boot Configuration Data BCD identifier: 00000000-0000-0000-0000-000000000000 Recovery image location: Recovery image index: 0 Custom image location: Custom image index: 0 REAGENTC.EXE: Operation Successful.

ReAgentC will not enable

Oh derp!

Copying the Recovery folder from a known-good-working computer and pasting it to the not-working computer does not work. C:\Windows\System32\Recovery\ReAgent_Merged.xml1 file is custom created on-the-fly for each machine.

1. Check to see if Windows\System32\Recovery\ folder exists;
   • if N skip to next step;
   • if Y rename it RecoveryBUP or something similar, then continue;
2. using 7-Zip or similar navigate the installation media to ...\Sources\ install.wim or install.esd
3. double-click either and go to ...\1\Windows\System32\
4. click the Recovery folder and tell 7-Zip to extract it to the target machine at C:\Windows\System32\;
5. reboot
6. Go to Settings > Update & Security > click Recovery in the left menu list;
7. under Advanced startup click Restart now
8. You should now see the full Recovery console like this:

MBR2GPT.EXE is a Microsoft program included free in Windows. If running Windows 10 v 1803 or later and the objective is to convert MBR to GPT with NO data loss, MBR2GPT.exe will do that. It is fast and works well. MS posted a video of it in use at their site. There is also an updated step-by-step tutorial at WindowsCentral with pictures. The steps follow:

In order to enable UEFI on a UEFI-able system that has been using BIOS because it was running Windows 7 or some such, the MBR (master boot record) first must be converted to GPT (GUID partition table):

• click Command Prompt in the Recovery Console to open an elevated command prompt without the Windows GUI;
• that should bring you to C:\Windows\System32;
• type MBR2GPT.exe /validate;
• type MBR2GPT.exe /convert and await the successful conversion;
  • there may be an error message about reagentc.exe, you can ignore that until after you change the CMOS/BIOS settings

now change BIOS to UEFI:

• reboot and tap F12 continuously before the Windows logo appears (or whatever key your device requires to enter the BIOS settings)
• change boot to UEFI from BIOS & reboot
• DONE

Now, ensure the Recovery console is as you want it...

1. In Windows launch an elevated command prompt and navigate to C:\Windows\System32
2. type reagentc /info and tap [enter], if disabled
3. type reagentc /enable and tap [enter]

RESOLVED & DONE with much thanks to SIW2 and NavyLCDR!

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?
