Windows 10: 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: https://answers.microsoft.com/en-us/windows/forum/windows_10-update/windows-10-re-kernel-is-missing-or-contains-errors/a3e7cd53-537a-4a58-ace3-9e03e3d3213f. I scanned the system withsfc /VERIFYONLYand 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 wo

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.

REAGENTC.EXE setreimage /? The parameters did not work or not correct,..,ect.

Note: I already know my hoe to get he information from the

bcdedit /unum /v

command but don't know the parameters to to use with the REAGENT.EXE /setreimage

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!
