I've spent the past three days trying to upgrade from Windows 10 to 11 and have been pulling my hair out trying to get it to go through. I initially started with using the Windows Installation Assistant, but it was never able to complete all the way through at the end. I have always been met at the very end with an "Undoing changes made to your computer". I've checked with the PC Health Check and I'm good, I've got plenty of storage left (202 GB), and I've also already ran as admin in a command prompt both;

DISM.exe /Online /Cleanup-image /Restorehealth

sfc /scannow

I've checked for any unknown devices in device manager and have checked for any driver updates. I've checked for Windows Updates and even ran the troubleshooter. I've also ran the upgrade through both C:$GetCurrent\media and using the ISO, while also unplugging every external device save for just my monitor so I can watch it. I have done all of these things and I'm still getting "Undoing changes made to your computer" however, after I started using the $GetCurrent and ISO options I've started to get a prompt after the upgrade fails now saying;

0xC1900101 - 0x40017

the installation failed in the SECOND_BOOT phase with an error during BOOT operation

I would also really like to not have to do a clean installation, requiring me to go through the process of backing up files before it wipes them all as well if possible. From what I've been able to gather from most advice I've seen elsewhere, there seems to be some driver error I'm getting, but for the life of me I can't tell what it might be. I would really love some help and if any other further information such as any kind of specs or logs are needed I would be more than willingly to update.

Please run the fixlist below.

  • Download fixlist.txt
  • Save Fixlist.txt to the same folder as FRST64.exe.
  • Close all programs.
  • Launch the Farbar Scanner tool and click "Fix".
  • Restart Windows when prompted.
  • Upload the output log file (FixLog.txt) to your OneDrive.

NOTE: The fixlist.txt script was written specifically for this user and for use on that particular machine. It is not recommended to run it on another machine, and don't run the same fixlist.txt more than once.

    Hopefully this works / is correct. I've never tried sharing a .zip folder through OneDrive before. If not let me know.

    0xC1900101 - 0x40017 is usually caused by bad device drivers. Please share your Farbar scan logs for analysis.

    • Download Farbar Recovery Scan Tool 64-bit FRST64.exe
    • If the OS language is not English, rename FRST64.exe to FRST64English.exe.
    • Run the program. Don't check or uncheck any options. Click "Scan".
    • Add the two logs, FRST.txt and Addition.txt, to a zip archive.
    • Share the zip file on OneDrive or GoFile.io, and post the link here.

    Note: If Microsoft Edge or Chrome mislabels the Farbar Scanner executable as PUA/malware, choose to keep it by tapping … in the bottom bar, choosing Keep, and then choosing Keep anyway in the dialog that appears. See this screenshot. It's a safe tool used in most antimalware forums.
