Unable to access the Advanced Startup Options (WinRE)

Perfect: is there any specific instruction I can follow to do that?

Here are the instructions. There was also a PowerShell script to automate the task. https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/add-update-to-winre?view=windows-11

Example (the OP was using Windows 10 PC, though) https://answers.microsoft.com/en-us/windows/forum/windows_10-update/windows-10-update-kb5057589-error-0x80070643-april/0f192298-7939-4b58-86a6-a860d0f90f6b?messageId=d5203f12-9904-4d9a-aab6-9637759a9e0a

Anyway, Windows Update will do that automatically. You may wait for the May 2025 Safe OS dynamic update.

Actually, now I'm okay with WinRE in the separate recovery partition and I've no reason to do that. I was just curious to understand how Windows decides whether to look for the WinRE files in the Windows\System32\Recovery directory of the C drive or in the Recovery partition created specifically for this purpose.

When you enable or disable WinRE, the BCD changes. You can see that by running bcdedit /enum all. The winre.wim path will be referenced in the BCD when WinRE is enabled.

Hi Moris,

We're not done yet. Wanted to go step by step. I'll let you know once it's done.

Boot into Windows.

From admin Command Prompt, run:

• diskpart
• select vol S
• remove
• set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
• gpt attributes=0x8000000000000001
• exit
• reagentc /enable
• reagentc /info

Post the output.

1. The existing Winre image is good. It's fully updated.

There is no recovery partition. Although Winre.wim can exist in the C drive, creating a separate recovery partition is suggested. However, the C drive might run out of disk space in the future; currently, it has 11 GB of free space. You can use AOMEI or a similar tool to shrink the D drive and create unallocated space before it. Then, extend the C drive as needed.

(or)

Now that you've replaced the wim file, re-enable Windows Recovery Environment (WinRE). It will be placed on the C drive as before.

Run:

reagentc /enable

reagentc /info

If you still get the ATTEMPTED_WRITE_TO_READONLY_MEMORY BSOD error, please share the contents of the C:\Windows\Minidump folder if there are any dump files there.
