Hi, I can't upgrade my win 11 from 23H2 to 24H2

Here is panther and rollback logs.

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.

    Yes, I recon BitLocker blocked access to a boot device.

    Great. I'm glad it's resolved.

    Hi Ramesh,

    Yes, but it resolved the initial issue and allowed the upgrade process to progress further.

    I'll describe everything in the next post,

    Hi Alexey,

    Thanks for the update.

    It seems you were able to resolve the second error, 0xC1900101 - 0x40017. Am I correct?
