Hrmm...it seems to be mostly g3258 users that are experiencing a SAFE_OS error while trying to upgrade to windows 10. So here's the gist of what I read so far:
- g3258 processors are receiving "SAFE_OS" error while attempting to upgrade or fresh install of windows 10 if overclocked and using an H, B, or Q series board. Z board users do not appear to be affected by this.
- To fresh install or upgrade to windows 10, users must set to stock speed and, in some situations, use only single core.
- Users who have installed windows 10 on an H, B, or Q series board will experience the "Bootloop death" if they attempt an overclock afterwards.
- This problem seems to be associated with update "KB3064209" after build 10130.
- Build 10130 introduced an Intel microcode "mcupdate_GenuineIntel.dll" that appears to be interfering with overclocking
- Some windows 10 users are only able to overclock just 1 core after this build.
- Some windows 10 users have been able to restore full overclockability after deleting or renaming the Intel microcode.
- Some windows 7, 8, and 8.1 users have also had this same overclocking issue after the microcode was updated on their system.
- Microsoft claims it is not on their end but rather it's a problem with the aforementioned Intel Microcode.
- Intel claims to be working on correcting the faulty microcode.
So for anyone who is considering overclocking on a post 10130 windows 10 build...you may have issues if you're running a non-Z board. I will attempt the fix listed in the link below and update.
Here's a summary of this issue and possible solutions on the MS forums:
