Expand Recovery Partition and Enable Windows RE with MBR Disk

I recently increased the size of my Recovery Partition and had difficulty enabling Windows RE in the larger partition. However, Windows RE appears to be working now as shown below.

What is the proper sequence of steps required when using an MBR disk? I started with the steps shown below.

1. Reagentc /disable
2. Shrink C: partition 283 MB using MiniTool Partition Wizard
3. Expand Recovery Partition to 850 MB
4. ..

Initially WinRE.wim was found in C:\Windows\System32\Recovery when disabled and C:\Recovery\WindowsRE when enabled.

It was not clear whether the Reagentc /setreimage command was required. The Microsoft instructions shown below do not include the /setreimage command.

Windows 10 Home - Version 22H2 OS Build 19045.3803

Thanks for any help.

It seems to be okay. You don't need the Reagentc /setreimage command.

Do this command:
Dism /Get-ImageInfo /ImageFile:\\?\GLOBALROOT\device\harddisk0\partition3\Recovery\WindowsRE\winre.wim /index:1

Post the return.

Uefi or mbr working.

You must do this command on the computer and the Windows disk on which you applied the kb.

The dism command I configured according to your first post, harddisk0 and partition3

Thanks all for the help.

The recovery environment is working correctly. I tried the ReagentC command boottore last night on the MBR system and the system did boot into the recovery environment.

In regards to my original question on the sequence of steps, is it necessary to delete the expanded recovery partition first and then create the new one as suggested in the Microsoft instructions?

I believe I just did the quick format and set ID=27 for the MBR disk.

Thanks all once again for the help.

Since the Microsoft instructions did delete the partition, it's surprising that they didn't include the /setreimage command.

I think my difficulty resulted from initially using an incorrect ID for the MBR partition. In addition, /setreimage commands that I tried did not appear to work.

It looks like I could have just done a Diskpart quick format followed by Set ID and then ReagentC /enable.

If your disk is MBR, run create partition primary id=27

quick format fs=ntfs label=”Windows RE tools”

And because I had a small problem on an old mbr computer
I redid just after these commands above the command set id=27

Edit: When you do reagentc /disable the wimre.wim file is moved from the recovery partition to the c partition.
No need /setreimage command.

Is it necessary to set the ID before the quick format?

I believe I performed those steps in the opposite order.
