Driver Problems - Error Code: 0xC1900101 - 0x20017

[RGary774]

I've used FlyBy11 V1.6 with Win11_24H2_Englishinternational_x64.iso, on 3 Laptops. All were updated to the latest Win10.
The DELL Inspiron N411Z completed the upgrade from WIN10 to WIN11 successfully. The other 2 (DELL Inspiron M5030 and HP Pavilion dm3-111sa, both 2011/20212) failed after the full screen 'Installing Windows Server' reached over 90% complete - they then rebooted. Upon restart they displayed an error.

We couldn't install Windows Server - We've set your PC back the way it was ...........
0xC1900101 - 0x20017
The installation failed in the SAFE_OS phase with an error during BOOT operation.

I am compliant with all suggestions relating to the 0xC1900101 error codes, which suggests it's a driver problem, but Windows update doesn't identify any driver problems. Any ideas?
If it's a driver, how do I identify which driver, or bypass the problem.
Thanks
