Same issue (C1900101-40017) here... (regular upgrade from W7/SP1 x64)
Asus N56VM (Intel Core i7 3610QM @ 2.30GHz, 6GB RAM, 512GB SSD-Samsung 840 Evo)
Upgrade process Windows 10:
- Installing features and drivers 100%
- Preparing automatic repair
- diagnosing your PC
Only option is roll back to Windows 7....
The log file (setuperr) last row:
2015-08-04 14:50:46, Error [0x080863] MIG MigHost: CMigPluginSurrogate::COMGenericThreadingHostThreadProc:
LoadAndRegisterServerInThreadContext() failed hr=0x8007007f.[gle=0x0000007f]
The MediaCreationTool results in the same error, but with more explanation:
C1900101-40017
Installation failed in the second_boot phase with an error during boot operation
Solved C1900101-40017 ;-) (aug 6th 2015)
After the failure during the upgrade process go to advanced/startup settings en activate disable drivers signature.
The upgrade process continues with configuring and completes with boot Windows 10 ;-)
