I've tried setupdiag, cleanboot, driver update, unplugging all external hardware, sfc, chkdsk, dism. Nothing helped.

Hello,

I'll try to describe everything from scratch:

Note: I have a system drive running on an NVMe disk and a data drive configured as RAID 1. Additionally, BitLocker is enabled on my system disk.

First Issue:

During an in-place upgrade, the installation proceeds through the initial checks and starts the upgrade process. At this point, I see the following screen:

Image

Once the process reaches 95%, the PC reboots but fails to start. After several failed attempts, the system rolls back the upgrade, and upon reboot, Windows displays an error message:

Image

Solution:

As suggested by Ramesh, I completely disabled the SATA controller (or you can switch it to AHCI mode) since it wasn’t required for my Windows installation. This allowed the upgrade process to proceed further.

Second Issue:

After completing the first phase, the PC reboots at 95% (as mentioned earlier) and continues installing the update up to 30%.

  • After the second reboot, the installation reaches 100%.
  • However, on the final reboot, a BSOD with the error "INACCESSIBLE_BOOT_DEVICE" appears.
  • After several failed attempts, Windows rolls back the installation and upon reboot, Windows displays an error message: Image

Solution:

  1. Deleted RAID drivers (though I don’t believe this was the cause of the issue, just noting it for reference):
    • rccfg.inf
    • rcraid.inf
    • rcbottom.inf
  2. Completely disabled BitLocker, as suspending it didn’t resolve the issue.

    Hello,

    I can't see the OneDrive share. Please make sure that anybody on the internet with the link can view.

    Also, error 0xC1900101 - 0x20017 is just a generic rollback code.

    Hope this helps.

    Hi Alexey,

    We can eliminate some drivers and try again. Unfortunately, it's a trial-and-error fix.

    1. Create a Restore Point.
    2. Backup the registry using Acelogix Regbak.
    3. Run the fixlist below.

    Download fixlist.txt

    Save Fixlist.txt to the folder where FRST64English.exe is located.

    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.

    1. Enable Memory Integrity. To enable memory integrity in Windows, go to Windows Security > Device security > Core isolation details > Memory integrity. If it shows any incompatible drivers, post the screenshot here.
