Windows 10 Boot issue after Gigabyte GA-Z77-D3H reflash to F22

I had some issues when upgrading to windows 10 – when sleeping/waking I sometimes got a blue screen error which forced an immediate reboot. I was running bios revision F18, so elected to upgrade to the latest non-beta version which was F22 at the time.

Reflashing was fine using qflash straight from the bios having placed the new bios image on a flash drive. It was also safe as the motherboard was dual bios so wouldn’t brick itself if I accidentally had a power fail whilst flashing.

However, Windows 10 would not boot after the reflash. The reflash reset all motherboard settings to default, so after some investigation I noticed that the Peripherals, SATA mode selection was set to IDE rather than AHCI, the latter being required by Windows 10 (and also used by my Windows 7 installation previously). Changing this allowed the system to safely reboot, only needing a slight repair fix by windows which took only a few seconds. All was then well. I had also tried to set the OS type to “Win 8” rather than the default of “Other”, but this was in fact a red herring – not sure what this setting does exactly (claims to allow certain Windows 8 features but does not elaborate), so in the end I just left the setting at “Other”.

This fixed the issue.
