Just wanted to save someone else some time if they have a G3258 and are trying to install Windows 10. Upgrade, clean install, upgrade install. All versions of the current retail Windows 10 version, have the offending code installed. This currently applies to all versions of Windows 10. Current as of July 29th...
Some people have reported being able to install W10 if they are not overclocking, and in some cases disable one core of the G3258. My system is completely stock and still will not install.
**Update #2**
THE ONLY MANUFACTURE TO CREATE A WORK AROUND IS ASROCK SO FAR.... SEE THREAD HERE (ASrock website with custom BIOS update work around). ASrock actually has listened to its forum users, and created individual BIOS updates for people so they can install Win 10, and USE both cores of the G3258...
Many people with G3258's will not be installing Win 10. Hopefully this gets fixed ASAP.

What happens:
Installing Windows 10 via the update tool from Windows 7 OR 8.1. ALSO OCCURS WITH A CLEAN INSTALL ISO! All CURRENT Retail and upgrade builds contain the code that does NOT allow the installation to work properly. The update runs checks, downloads Windows 10, and restarts. During the restart, the error occurs. There have been more than a few different error codes, but the error I got in particular was listed below.. When the computer restarts, the following error occurs:
Error:
0x1900101-0x20017 The installation failed in SAFE_OS phase with an error during BOOT operation
Problem:
Intel sent out a microcode update to Microsoft, apparently limiting OC'ing and some "features" on the G3258 specifically. MS integrated this microcode into a MS update, KB3064209. This update happened to both Windows 7, and Windows 8.1, and it also is currently BY DEFAULT installed in the current retail/upgrade build of Windows 10, both 32 bit and 64 bit. If you un install the KB3064209, and try to repeat the Windows 10 install, it still does not work, because the microcode is already injected into the Windows 10 retail version that is current.
Manufacturer responses:
Initially MS and Intel did NOT answer. This has ben going on since an update last month to Windows 10 when it was not ready for retail. Intel also did not acknowledge the problem at the time. Now today since Win 10 was "officially" released, the internet has been asking for answers from both sides.
(There have been various posts on different forums about official responses from Intel and MS. I have not directly had contact with either, so I decided to remove this part of the OP)
EXCEPTIONS / Temp Work Around:
Some users have reported disabling one core on MSI boards allow the G3258 to install windows 10. Other users have stated if the brand motherboard supports disabling cores, the installation CAN work. But you essentially end up with a single core processor. And since Win 10 uses a hashtag type hardware signature as a "Key" during the upgrade process, changing to dual core later may nullify the activation. In other words, its a waste of time....
