Windows 10 to 11 error 0x800703ee fix?

Hey everyone, my pc in health check is fully compatible for windows 11, For over a year I have tried to update to windows 11 just reading through different forums and trying different methods to solve 0x800703ee, none seem to work. Can someone please walk me through all the possible solutions, I will gladly retry certain things and upload screenshots until we can get it figured out.

Hi Kotyba, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

I understand the issue you have, there is nothing to worry I am here to help, this error occurs when there is a miscalibration on Windows update and since the PC health check says that your device is compatible, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

Kindly follow the steps from this link:

Let me know how it goes and I hope that helps.

Bernard

Hey Bernard,

Thanks for the quick response, after install attempts to happen I am met with a message that states "we can't tell if your PC has enough space to continue installing Windows 11" my only drive has 170 gb of free space, any thoughts?

Hi Kotyba,

The EFI boot partition or the BCD might be the problem.

Please run the bcdedit command (from admin Command Prompt) and post the output.

Also, share the following setup log file on OneDrive/Dropbox and post the link here:

 

  • C:\$WINDOWS.~BT\Sources\Panther\setupact.log

Hi, thank you so much for that information, since the in-place upgrade didn't push through, we need to run a custom installation to fix the issue, however, the process will delete all apps but will retain all files on the PC, if you are okay with that, you may follow the steps provided below:

Since you already downloaded the ISO (Windows 11 ISO), kindly right-click on ISO then click Mount> Click Sources folder>then look for Setup.exe inside the sources folder

Then follow the second picture to the last from this link:
