@hancor Thank you so much! I’ve just successfully flashed it and everything seems to work fine. I even got hi-res boot screen now for some reason :). I wonder, where did you get the F10a bios? Gigabyte does not list it under the support section of this motherboard
You are correct the latest on the “official” gigabyte website is F9c which is listed as beta.
However, when you go to the following website for Gigabyte support you occasionally find later dated bioses which didn’t make it to the “official website” even though they are final release quality.
Use diskpart in windows from OS with the NVME connected as secondary drive (Direct from any CMD Prompt), or from Win10 installer ISO (press Shift + F10 on the first setup screen where you pick language) Remove all other drives, so only the NVME is there, and any other disk you will recognize by size/name etc - so you don’t accidentally wipe wrong things.
At CMD Prompt >>
>> Diskpart >> List disk << Here, identify by size, and then note the number which disk you will be wiping to raw here (If in windows, this #'s will match what you see the drives shown as in Disk Management) - Be sure you do not select your USB or main OS drive if in OS >> Select Disk # << here, replace # with NVME # you want to wipe to raw. >> Clean >> Exit
