We couldn’t install Windows 10; 0x8007002C–0x4000D

I was seeing the same damned error (“We couldn’t install Windows 10”; 0x8007002C–0x4000D The Installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation) on all four of my systems that I was trying to upgrade.

Microsoft may be changing a lot and trying to do better, but they’re NEVER going to succeed as long as they continue to maintain the mentality that error codes are a good thing.  I wouldn’t actually mind them if they provided a widely published and constantly updated database of what each and every Error code means.   But they don’t publish these codes widely, instead they only publish the one that a million people are complaining about.  And each new Error Code is as cryptic as the last.

Take the error code I mentioned previously:

WP_20150731_11_49_02_Pro“We couldn’t install Windows 10”
The Installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation.

The error was noted while Upgrading Windows 7 Ultimate to Windows 10 Pro.  The upgrade process would get to somewhere in the 83% to 85% range and would then go to a blank screen, no warnings or errors.  It would sit there for approximately 50 minutes until the system would just spontaneously reboot, with subsequent boot screen messages indicating that Windows was reverting to the previous Operating System, or something to that extent.

It turns out that what they really mean is to do the following prior to beginning the process:

1.) Uninstall any third party Firewall/Security and AntiVirus/AntiMalware software you might be using.
2.) After removing software, reboot your computer to ensure a fresh start.

After removing AVAST Business Antivirus (it’s really a great A/V solution, can’t beat that it’s free!). AVAST had some additional cleanup that required a reboot, so I elected to “do the reboot later” and then I also removed Malwarebyte’s AntiMalware (also a really great A/M solution, and is also free!). 

I then restarted each computer and then restarted the Upgrade Process, and then went back to playing a game to kill time while it re-downloaded everything all over again. 


Two other aspects that I should probably mention, as they could have some impact on your results:

1.) I was using the Microsoft Media Creation Tool to launch my upgrade process. 
2.) I started it by right-clicking on the file and selecting “Run as Administrator” just to be safe.

This time, each of the four systems ran to completion, and successfully installed Windows 10, so I can call this a success.  The fact that the error message never once spoke of this particular issue in all of my research proves that Microsoft really needs to start working on those error messages, for everyone’s sake (and sanity).

Best of luck in your Upgrading efforts!

  1. I had the exact same error 🙁 but I don’t have any third party firewall/security/AntiVirus/Antimalware software installed, only Windows defender. Any ideas of how to solve this problem?

  2. Try doing a clean boot. Run msconfig.exe, hide all Microsoft services and disable the visible services. Then, disable all start up items and reboot. Do the upgrade again and that should work.

  3. First of all, thanks for trying to help. I’ve just followed the steps described here https://support.microsoft.com/en-gb/kb/929135 restarted my computer and tried to update again, it didn’t work 🙁 I got the same error. I had tried disconnecting all my peripherals except the keyboard and mouse, that didn’t work either. I don’t know what’s wrong :/ it’s so frustrating…

  4. Sounds like you’re on the right track Cristopher! I also had to do some extra sleuthing that I didn’t mention in the article, but that also helped to paint a more accurate picture for me.

    First I rebooted my computer and read a file in a hidden folder, as is indicated in this thread. This is the point where I saw references to my AVAST Antivirus.

    Then I followed this step to ensure my existing update files were purged:

    It was after that I uninstalled my AVAST and AntiMalware.

    Since you don’t have any 3rd party security software, then your problem may unfortunately lie elsewhere.

    Let me know what happens!

  5. Thank you kind sir for writing this article. As the problem you described to have had is identical to mine, the solution (supposedly tested on 4 pcs) must be as you have written, because i also use avast, aswell as malwarebytes at times.
    I had almost given up on upgrading to W10 because i ran out of patience (also because some other threads implied that the issue had something to do with windows updates – which i just cba to deal with), but now this article has given me hope, and I’ll try again tomorrow after uninstalling the mentioned software and report back on how it goes :).

  6. Thanks for the reply…

    I’ve been googling the error code like crazy and tried everything that is suggested in various webpages. At this point I think I’ve tried pretty much everything, but I just keep getting the same error code and it just rolls back to Windows 8.1…

    I can’t make much sense of the “setuperr” file. To top it all, I’m not even getting any answer from Microsoft and something tells me I never will :/ http://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install/we-couldnt-install-windows-10-error-0x8007002c/4aac7698-2cad-4244-9ee7-3fd4b8d7974e?tm=1438655383357

    I think I’m about to give up…

  7. Shoot me a copy of your setuperr file. I’ll have a look at it. David at matsonconsulting dot com.

  8. Yes, I feel very confident that your future attempt will work well. I only used the 4PC point to illustrate that all four of my upgradable systems suffered the very same issue, which statistically makes it a much more likely issue that others may suffer the same problem. And that all 4 PCs worked fine on subsequent attempts with AVAST and AntiMalware removed.

    Best of luck Benjamin!

  9. Everything worked out well at the end, so thanks again !
    Still don’t know why/how avast causes this issue, since I have upgraded another pc while running AVG and it worked out fine.
    oh well… glad i got it sorted out – thanks to you 🙂

  10. Excellent news! Glad to hear it!

  11. David Matson, good news! 🙂 I finally managed to upgrade to Windows 10! The problem was this: I have a little program called “Folder guard” that I use to protect my important folders with password. It turns out that Windows was trying to migrate those folders, but since they were protected, it wasn’t able to! So I removed all the passwords from the folders and tried to update again, it worked without any major problems, and all my software seems to be working as expected 🙂 if I only I had known sooner! The solution was so simple… Thanks to you, I was able to figure it out. Now, let’s enjoy Windows 10! =)

  12. Wonderful news Cristopher! I’m so very glad that worked-out for you. And thank you for replying back after the solution was determined, knowledge is power!

  13. Hi Christopher. Thank you. After countless hours trying to solve error code issues and over 20 attempts to install W10 on my 3 PCs, you hit it out of the park with your discovery. I also had the great Folder Guard program on all of my PCs but as soon as I released the passwords, voila. SUCCESS. I am not sure what the MS policy is on publishing fixes to known installation problems, but it would be more than helpful for them to mention your discovery. I am pretty sure that we are not the only 2 persons with Folder Guard. Well done sir and thanks.

  14. Hi Scott. Wow, I’m so glad this actually helped someone. It took me days to figure it out, but I managed to do it. It goes without saying that I agree with you that Microsoft should mention this so other people won’t have to go through what I had to. Surely there are more people using file/folder protection software. Thank you for your words and let’s enjoy Windows 10.

  15. Good to know – updating an old Win7 machine and it has Avast on it and the Media Creation Tool keeps crashing out.

  16. I had to uninstall SonicWall Global VPN client as well as any AV/Anti-malware software. Making my second run at an upgrade now. I’ll come back and confirm my success and any additional software removals as needed.

    Update – That did the trick. I have a successful upgrade.

  17. Excellent news Victor! And a big “Thank you!” for updating us on removing the SonicWall VPN Client, it is greatly appreciated!
