windows 8 Unabled to complete Win 8 to Win 8 Pro upgrade

[News Bot]

I can usually figure stuff out on my own, but this one has been driving me nuts for 2 hours now as it's just one of those things that "should" just work.

I've got a Win 8 test machine here with our MSDN copy of Win 8 on it. I'm trying to "add new features" and get it upgraded to Win 8 Pro with our MSDN Win 8 Pro Key.

 

The Win 8 Pro key is input and accepted and the upgrade takes off. Upon 1st reboot feature installation gets to around 90%, then fails. 2nd reboot it tries again and immediately fails, then reverts the system to Win 8 Basic.

 

Error upon logging reads: "Failed Adding Windows Features. Previous version of windows restored. Contact support".

I have scoured the net and try several solutions including:

1. Clean boot without optional apps and services: Same Results

2. Diagnostic boot: unable to verify key as needed services for wifi are disabled. (Guess I could enable them all, but was skeptical).

3. sfc /scannow. Complete with no errors found

4. Ran windows update troubleshooter: found 2 issues and resolved, but same results upon pro upgrade.

5. Applied all available updates: Same Results.

6. Event logs show no associated errors.

 

I'd rather not spend 4 hours on the phone with MS for this issue, and would rather not have to reinstall our test machine.

Any assistance would be appreciated.

 

Thank you.
