Hello All,

We have about 100 PCs, Dell OptiPlex 5000, some running Windows 11 23H2, some 22H2, and only 4 PCs running Windows 10 22H2. Since the drop in support for Windows 10 on October 14, we have been unable to upgrade to the latest Windows 11 Build. We continue to get the message:

We've set your PC back to way it was right before you started installing windows 11. 

0xC1900101 - 0x40017 

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

We have tried all available steps outlined on the internet to fix this issue but nothing works.

How do we overcome this hurdle?

Thanks, everyone.
