Cannot update to 24H2 because of partition error

Hello, I really need help with performing the update to Windows 11 24H2 update.

I have tried to search for update in Windows Update multiple times, and yet it keepts telling me I'm on the latest update. There are nothing in the optional section either. This is despite the fact my build version is 21H2, which is very old now.

I have tried downloading the Windows Update Assistant, but that was to no avail because every time it keepts telling me "we couldn't update the system reserved partition". I have 95 free gbs on my OS:C and so I have no idea what is causing this. I tried deleting temporary files, using the CMD and create a Y drive then deleting fonts through it, labelling the product file to .old and even tried a set of command to restart registries. The Update Assistant or the ISO version, both returned with the same message.

I have grown quite desperate now since I realized Windows never even offered to update me to 22H2 and 23H2. All the tutorials on Youtube all pointed to the MS guide to deleting the fonts. I ran out of options, and I can't contact any agents because the system keep telling me my account was logged in too many times.

Hope someone can help me here, thank you.

Here is my spec:

Device name LEGION5-KB

Processor AMD Ryzen 7 6800H with Radeon Graphics 3.20 GHz

Installed RAM 32.0 GB (31.2 GB usable)

Device ID CE7ECE7D-319F-442B-B4F1-B2ABD3A4024F

Product ID 00330-81480-16870-AA476

System type 64-bit operating system, x64-based processor

Pen and touch No pen or touch input is available for this display

    From admin Command Prompt, please run:

    • MD c:\dellbios
    • CD /d y:\efi\dell\bios\recovery
    • Move *.rcv c:\dellbios\

    Post the output.

    Rerun the 24H2 setup.

    For those who may not be aware, this issue has been prevalent in Windows since the release of Windows 8. Microsoft removed the option to set EFI partitions during the initial stages of a Windows installation. Even more concerning, they have not extended the partition despite being aware for years that this causes problems during automated updates. The internet is filled with reports of this issue, yet Microsoft has not provided a resolution, only workarounds. If you use BitLocker, you may also encounter blue screens due to this problem.

    We faced the same issue with Windows 10, and now it persists in Windows 11. Here are your options:

    A. Delete the Fonts folder and hope it resolves the issue. B. Use Command Prompt to delete the existing EFI partition and create a new, larger one after shrinking the OS drive. C. Use third-party software to extend the EFI partition on the fly (note that no free tool effectively does this). D. Completely reinstall Windows, for example, upgrading from W11 23H2 to W11 24H2.

    This is a significant issue for us and many businesses, as we recently updated to Windows 11 23H2 and now find that the 24H2 update will not install without extending the EFI partition. We are deeply disappointed with Microsoft's blasé attitude towards this problem. Managing a network of over 400 systems and encountering this issue as a professional service is unacceptable. We hoped this would be resolved in Windows 11, but unfortunately, it has not been.

    Terrible service!

    Follow the steps under "Windows 10 with GPT partition" in this link. It applies to Windows 11 also.
