Windows 10: How do you test the Windows RE partition, set with the reagentc /setreimage /path command?

I just copied all data from a prior 1TB HDD to a new 512GB SSD. Since the Windows RE partition was at the "end" of the 1 TB drive, I copied that partition separately, and reduced the size of C: from 800+GB to 300+ GB to fit the new drive.When I was done, I installed the 512GB drive, but hadn't replaced the Recovery partition yet. I decided to test the "before" and "after" replacing this partition to make sure replacing it worked.To my surprise, holding the shift key while clicking restart still took me into the Windows Recovery Envirionment blue screen, choose Continue, Troubleshoot, other de

Reagentc failed

I was in the same situation but I had a hard time to set the path; eg: reagentc /setreimage /path D:\Recovery\WindowsRE

It wouldn't let me. I had to do the following inside DISKPART (Using your snapshot for the syntax):
- "select disk 0"
- "select volume 0" (your partition listed #1 as the Recovery)
- "assign letter = D"
Note: commands without double quote

After above steps, "reagentc /setreimage /path D:\Recovery\WindowsRE" will work.

The file ReAgent.xml under C:\Windows\System32\Recovery will be updated (if you made a backup prior, you will notice the updated timestamp)

Another way instead of using Drive letter, syntax is as follow:

"reagentc /setreimage /path \\?\GLOBALROOT\device\harddisk0\partition1\Recovery\WindowsRE"
(note the bolded variable that matches the information from DISKPART)

When REAGENTC.EXE: Operation Successful. Windows RE status will always be disabled still.

In order to enable Windows RE status, you need to reboot into the Bios then turn off Legacy Bios in CSM and Secure Boot will automatically pickup the Windows EFI System Partition. Save the Bios and boot into Windows.

Once started, Windows RE status will be Enabled automatically. No need to enable it.

In System Information Bios Mode will be UEFI.

Hope this explain a bit more of the final step as I was struggling why I couldn't enable the RE status when "reagentc /setreimage /path D:\Recovery\WindowsRE" was successfully completed.

Good luck!

 

REAgentC.exe tool & its /setreimage command

Hello.

I'm dealing with a problem regarding Windows RE rescue drive. Although, it can be created, I can not boot from it (my problem is described here: Redirecting).

I scanned the system with

and some errors were found. Before I start to fix them, I want to be able to do a bare-metal system recovery from a backup if something goes wrong. Unfortunately, a backup solution I use (Veeam Agent for Microsoft Windows Free) needs to have a working Windows RE to create a rescue drive, and so the circle is closed.

Following a Veeam Knowledge Base article (KB2685: Veeam Agent – Windows recovery image file not found) I try to make it possible to create a working rescue media. Their procedure uses a Windows REAgentC.exe tool at some step. After writing a

command I'm getting an error message:

Although I've read a Microsoft documentation (REAgentC command-line options), I still don't understand how to use /path and /target arguments together with /setreimage command.

Could someone explain to me, what does a

argument in the above piece of code stand for? Is this the path to the recovery partition on the system drive (the one that is located after a system partition)? Any help will be appreciated. Regards
Dominik

 

ReAgentC cannot unmount recovery image after applying update package

See Step 1 ("Reagentc /setreimage" command-line) in that linked MS article in my previous post.

If you've re-created the partition, you need to follow all the steps in that article.
