How to fix Windows 11, version 24H2 (repair version) Download error - 0x800703ed?

Gaurang Vichare 20

It's been months since I have not been able to update Windows 11. Each time I do so via Windows Update in the Settings, I get "Download error - 0x800703ed".

I saw online that I can do an in-place upgrade. I tried doing so by running the setup in the ISO file. But I get the following error:

"setup has encountered a critical error Sorry, we're having trouble determining if your PC can run Windows 11. Please close Setup and try again. Error code: 0x800703ED - 0x40008"

This may or may not be of importance but I had dual booted my machine to use Linux Mint a few months ago. I had then promptly uninstalled Linux Mint. Did that perhaps mess up some disk partitions or file systems or something?

Run from Command Prompt admin:

diskpart
select disk 0
select part 1
set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b override
gpt attributes=0x8000000000000000
select disk 1
select part 1
set id=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 override
gpt attributes=0x0000000000000000
exit

Post the screenshot of the output window.

Ok. See if you can upgrade to Windows 11 24H2 or 25H2.
Ramesh Srinivasan 174.7K Reputation points Volunteer Moderator

Note:

If you already have 24H2, no need to do a repair installation.

Install the latest cumulative update instead.

Any update?

I was able to update my device to Windows 11 Home 25H2.

But now I have a different problem possibly due to diskpart commands I ran earlier. I now see a Local Disk (E:) which was not there before. It is empty and I can't open it. Is there any way to revert that?

Why don't you delete the volume E: in disk management?

I deleted volume E and extended volume D. It converted volume D from a basic disk into a dynamic disk. I am not certain if that is of any consequence regarding video games stored on it, but correct me if I am wrong, to convert it back into a basic disk, I'll need to delete it and recreate it as a basic disk, yes?

To address the download error 0x800703ed when trying to update Windows 11, version 24H2, you can try the following steps:

Check Disk Space: Ensure that you have enough free disk space on your system drive. Windows updates require sufficient space to download and install.
Run Windows Update Troubleshooter: Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update, and run the troubleshooter. This can help identify and fix issues related to Windows Update.

Reset Windows Update Components: You can reset the Windows Update components by running the following commands in an elevated Command Prompt:

   net stop wuauserv
   net stop cryptSvc
   net stop bits
   net stop msiserver
   net start wuauserv
   net start cryptSvc
   net start bits
   net start msiserver

Check for Corrupted System Files: Run the System File Checker (SFC) tool. Open Command Prompt as an administrator and type:
```
   sfc /scannow
```
This will scan and repair any corrupted system files.
In-place Upgrade: Since you mentioned trying an in-place upgrade, ensure that the ISO file you are using is not corrupted. You can download a fresh copy of the Windows 11 ISO from Microsoft's official site.
Disk Partition Issues: If you suspect that the dual boot with Linux Mint may have caused partition issues, you can use the Disk Management tool to check your partitions. Ensure that your primary partition is set as active and there are no unallocated spaces that might interfere with the installation.

If these steps do not resolve the issue, consider seeking further assistance from Microsoft Support or relevant forums for more tailored help based on your specific configuration and error messages.

Please run the following command from Command Prompt (admin)

dism /online /cleanup-image /restorehealth

Once done, upload the following file:

C:\Windows\Logs\CBS\CBS.log

Run:

bcdedit

Post the output.

Yes. That's most likely the problem.

Right-click Start, and click Disk Management. Maximize Disk Management, adjust the column widths in the top pane to make all the entries visible. Post a screenshot.

I can't attach the CBS.log file since it is 11.1 MB and the attachments can only be 3 MB at max.

Here is the output after running bcdedit in the command prompt:

C:\Windows\System32>bcdedit The boot configuration data store could not be opened. The system cannot find the file specified.

I have attached a screenshot of the Disk Management window.
