Yes. It looks good. Let me know if you have any questions.
How do I delete the EFI partition and then expand another partition

I first opened this issue in the MicrosoftAnswers community and before I could report back, it was Locked and moved somewhere (message did not indicate where). I was making progress and am pretty close to the end. I hope I am in the right place.
I was given the following instructions in one of the last posts:
|Ramesh Srinivasan [VM] has replied to your question Update Won't Install (error 800f0922). Unable to reload
Windows from media in Microsoft Support Community.|

|The Recovery partition's size is insufficient to hold the latest winre.wim image. I suggest converting the 356 MB partition to an EFI partition. Once done, delete the 100 MB EFI partition and extend the recovery partition. To convert the 356 MB partition to EFI, open admin Command Prompt and run: diskpart select volume D del part override create partition EFI format fs=fat32 quick assign letter=Y list vol list part exit · bcdboot C:\Windows /s Y: /f UEFI Post the output.|
I was able to follow the instructions butwas unable to post the results because the thread was closed.
Per the instructions, I tried to delete the 100MB partition with diskpart del partition override command but I got an error. I have a screen shot but don't know how to post it.
Ultimately, I am trying to re install the winre.image.
Any help would be greatly appreciated. I would also like to know where my original thread is located.

2025-07-16T15:50:07.5333333+00:00 Thanks for all of your help. Is there something I should have done differently during this case? The PC is a clients device and he is notorious for not keeping Windows updated. Also, is there something I should have or could have done differently from a case management perspective?
Always wanting to learn and improve here. -

You could have performed the in-place upgrade after nuking the 100 MB EFI partition and merging the unallocated space with C. That way, Windows 11 Setup would have resized the existing recovery partition instead of creating a new one.

I am trying to get in touch with https://learn.microsoft.com/en-us/users/ramesh-9281/ so he can continue to help you. I have left him a message so hopefully he will help you soon, not sure what time he is on so might take a few hours.
Use the following if you are happy using CMD etc or wait for Ramesh.
In Windows CMD admin run bcdedit /enum firmware then look at the {bootmgr} entry — especially the device line. It should reference partition=Y:. If it does then you can delete the 100MB partition by either from within Windows CMD
diskpart
select disk 0
select partition 4
delete partition override
Option 2:
Use a Windows install USB
Boot from the Windows 11 install media
On the language screen, press Shift + F10 to open Command Prompt
Run DiskPart again and delete Partition 4 using:
cmd
diskpart
select disk 0
select partition 4
delete partition override
If any partitions are marked system, etc by Windows delete will fail.

There can be different reasons of failure for that error code,
Can you post the cbs.log file. ( c:\windows\logs\cbs\cbs.log)
It may be the disk space issue but there are other potential causes thus the ask to see the cbs.log file which we hope will give us additional information.
See this page for a list of possible reasons.

2025-07-16T02:02:45.4866667+00:00 I followed the above and was able to delete partition 4. I tried to then combine the new unallocated space with the 356MB EFI partition and could not do it. I used Aoemi Partition Assistant (which I have used before) but the 356MB partition was greyed out and I could not combine it with the unallocated space.
I did check and the winre.wim file was not there but I was able to extract the install.esd from my Win 11 boot disc. I'm stuck with how to merge the 2 partitions.
I am also confused as to why I have two recovery partitions on my system disc.
I appreciate any help.
