You're welcome! Several things there you are doing wrong, some of these will cause this combo CPU/Win10 to fail.
1. Please load optimized defaults, then save and apply, reboot back to the BIOS and make all other changes you need. Do not load fail safe defaults.
2. No execute bit (NX bit) needs to be set to enabled. Default is enabled (w/ Optimized loaded), it's called no execute memory protect in this BIOS - set this enabled, should already be enabled once you load optimized defaults
3. Ensure Virtualization is enabled too
Don't use BIOS from random websites, only Gigabyte official site, or places like this forum where other users might help you update them.
You might be able to use the BIOS I posted with Qflash, but I am not sure, that's why I suggested to go ahead and use FlashSPI right away from DOS, save you some hassle maybe.
Sometimes Qflash will not accept modified BIOS images, so you get an error when trying, I assumed you might so said to use FlashSPI.
But yes, if you can flash it with Qflash without Checksum error or invalid BIOS image error etc, then go ahead and use Qflash.
