Knowing that a rollback has occurred is not a big deal since I know that already.


0xC1900101 is a generic code that indicates that a rollback has occurred. The error code is a combination of two parts The “result” code and the “extended” code. The Troubleshootingįirst, let’s examine the error code 0xC1900101 – 0x4001E. If you don’t know it, the out of the box experience is the step when Cortana starts talking and ask you for your language preferences, Keyboard selection, Network connection…etc. But the setup was stuck again at phase 4 when processing the OOBE (Out Of the Box Experience) and failed with the following message:ĠxC1900101 – 0x4001E: The installation failed in the SECOND_BOOT phase with an error during PRE_OOBE operation. The other 2 PC's I used a clean install/upgrade, this one I needed to keep the files and chose to keep files and upgrade.In my previous post, I showed you how to solve a Windows 10 Upgrade error 0x8007001F – 0x20006.īut just after overcoming this error, the Windows 10 upgrade process continues over phase 02. I had no other issues updating my other 2 PC's from Win7 machines to Win10. I have not run either file as I wanted feedback from one of your experts before moving forward.

There is another file I downloaded Restoro.exe from the same URL. I cannot cut and paste their info to this message for some reason, but I found it on: It's a download and they state a repair program and will fix the issue. MS has a page to fix this error but I'm not a programmer and found this instead from Advanced system Repair Pro. I went through the update several times and finally got it all the way through then got the error message:Īt the end of the upgrade it stated "could not install" and put me back into Win7.
