I have referenced one of my earlier posts in this reply.
I have been contacted for additional information from two moderators on this forum.
I have been contacted by a Microsoft support person by email and provided him with the files he requested.
None of these individuals have returned my contact. I have tried every single suggestion offered in this thread, have tried some of my own ideas such as updating the firmware on my Samsung 840 SSD drive.
When that changed the error code of the failure I was having, I decided to migrate Windows 8 to a different hard drive and try the update again.
Still the same failure and error code.
After four weeks of attempts and untold hours of effort all resulting in the same failure to update I decided to try a fresh install of windows 8.1.
I have several dozen software applications on my machine, so a fresh install set me up for hours of preparation and reinstallation of this software.
Adobe products have to be deactivated before the machine is decommissioned. Other software can be reactivated with the original keys while other software might require telephone authorization for activation.
Needless to say it is a much more time consuming process than what should have been an in-place upgrade.
After preparing deactivating the Adobe software I began the upgrade.
Using a Windows 8.1 ISO loaded onto a bootable USB drive and using a generic 8.1 activation key to begin the process.
I left all hardware in place, including dual Nvidia 660 video cards, a PCI eSata board and all of the peripherals running under windows 8.
The installation went quickly and perfectly. I activated Windows 8.1 with my original Windows 8 Pro key, then upgraded to Media Center with the Windows 8 upgrade key.
I installed all of the drivers for my Intel DX79SR motherboard and supplied USB Bluetooth/WiFi module, the Nvidia cards, the Syba eSata card, the Microsoft Keyboard and mouse and the Logitech Touchpad.
I followed by reinstalling the dozens of software packages I originally had on my Windows 8 installation.
It all works perfectly.
The really troubling thing is that I now have exactly the same machine as I would have through an in-place upgrade, yet the upgrade fails.
All of the hardware and software is the same, the drivers are the same, yet the upgrade failed.
This tells me that the problems we are having are introduced by the way the upgrade process is handled by Microsoft and has nothing to do with hardware or driver incompatibilities.
After an investment of 4 or 5 hours I now have a machine working properly under Windows 8.1.
It is quite disappointing that after a month Microsoft has not apparently been actively involved in correcting what is clearly a process error rather than a driver or hardware issue.
