Nothing, I repeat nothing in log you posted points to location of Users folder being the culprit. Googling your error codes gives two reasons for a failed upgrade install (repair install = upgrade install using same Windows version and edition):
- A third party AV program
- Corrupted boot records
For instance in this thread on Microsoft Community the logged errors are almost identical with yours: windows 10 upgrade fails, please help - Microsoft Community
Same issue and suggestions for a solution here and here.
Reading about those issues similar to yours gives a clear idea for a possible fix. I am not saying this will for sure fix your issue, I am only saying this is worth to test:
- Disable / turn off your antivirus application
- Boot to Windows Startup Repair
as told in this tutorial: Startup Repair - Run in Windows 10 - Windows 10 Forums
- When you reach Step 8 in above mentioned tutorial, select Advanced options
- Select Troubleshoot
- Select Advanced options
- Select Command Prompt
- Enter these commands, in this order (list numbers refer to example screenshot below):
1. bcdedit /createstore bcd
2. bcdedit / import bcd
3. bootrec /rebuildbcd
4. Type A
and press Enter
when asked to add installation to boot list
- Reboot PC, try repair install again
And once again: your issues have nothing to do with relocated Users folder. Of course you are the boss, it's your computer and you can move Users back to C: when and if you want to, but it does not resolve your issues.
Sysprep, the tool used to relocate Users folder is a native Microsoft tool. The method, relocating Users folder is designed by Microsoft to separate Windows and user data. It works perfectly when done correctly, for instance I have used this method for 10 years now on all my computers, since first beta versions of Windows Vista, and I have never had any issues with it.
Microsoft in fact made the method even better in Windows 10; until Windows 10 version 1511 you had to move Users back to C: before doing an in-place (repair or upgrade) install, but since version 1511 you can now do in-place install regardless where your Users folder is relocated. The only reason for this change was to make upgrade easier for those users like me who prefer user data on another drive.
Just because of this thread I did two repair installs this morning, to see it myself (have had no need to repair install, wanted to see it by myself). Both, one physical machine, one virtual machine have Users folder on E: drive, both repair installs worked without issues.
