Cannot update to 24H2 because of partition error

Anonymous

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

Hi Chris,

There is no need to revert anything. If the problem reoccurs when installing a quality update, delete those .ttf files again.

I think it can be left as it is because the lack of free space in the EFI partition will cause the quality updates to fail.

(or)

Delete the .ttf files in Y:\EFI\Microsoft\Boot\Fonts.

Then, copy the two BIOS files to y:\efi\dell\bios\recovery

Ensure there is at least 20 MB of free space in that partition.

Understood. Enlarging the EFI partition would be my next step then. As for now, after the 24H2 update is complete would you recommend I place the BIOS_PRE and BIOS_CUR files back where they were originally? (provided there is still space) And if I cannot do both files which one should I prioritize?

Thank you so much Ramesh! It worked like a charm. I was lucky I had similar circumstances by having a DELL laptop as well, although I must say that it caused an annoying inconvenience. Would you say this is a DELL exclusive problem or just a coincidence?

Anyways, thanks again!

I'm glad that helped. By default, the Windows setup creates a 100 MB partition, which is insufficient for OEM systems because these systems store the firmware updates (and the current UEFI firmware backup) in the EFI partition. On such systems, enlarging the EFI partition using a third-party tool (or creating a new EFI partition after discarding the old one) is the permanent fix.
