Problem with the crazy gigabyte X570 Master
Problem with the crazy gigabyte X570 Master
I've constructed my own systems for years and dealt with numerous gigabyte motherboards, yet this issue has never occurred before. Everything functions perfectly until I update the main BIOS to a newer version. Then Windows fails to load, though the backup BIOS works without problems—definitely not a hardware problem. I can still access the main BIOS and adjust settings, but Windows won’t boot. It displays a message indicating no boot drive is available. I suspected this might be a defective board, similar to what Gigabyte experienced when I filed a technical support ticket. However, I received a replacement from Amazon, assuming the original was faulty, and now it’s behaving the same way. There must be a software-related cause, but I can’t identify it despite extensive research. Any suggestions would be greatly appreciated. The only postcode listed is AA, which seems to be a placeholder or reserved code. Your help is much appreciated.
Your motherboard model is the Z390 Aorus Master. You're currently running BIOS version X and are planning to update to version Y. You're using an SATA SSD or an M.2 (NVMe) drive for booting. For instance, you have a Samsung 970 Evo Plus NVMe M.2 and needed to access the second M.2 slot because it wasn't showing up in the primary slot.
It seems the system is working well with the current setup—a gigabyte X570 Master, Ryzen 3800X, and a Samsung 4TB 860 Evo 2.5 SSD. Everything boots correctly in the backup BIOS, which is the factory F4 version. You've tried other BIOS versions like F7, F6, and even returning to F4, but the problem persists.
I’ve discovered only a few discussions about needing a new Windows 10 setup. It seems the issue might not be limited to just a couple of scattered forum posts. More insight is needed from someone with real experience. I’m just going to search for it myself.
Are you worried about too many components being installed on the motherboard, possibly blocking the PCI lanes required for the boot drive to work? I'm not sure, but I'm thinking it could happen—maybe a BIOS update will change how those lanes are managed. That's a long shot, but worth considering. Also, you might want to try a fresh installation using a known reliable BIOS, then update it later.
Have you checked the drives within the BIOS settings? Have you attempted to boot using the installation media? Did you use the built-in repair tool? A possible GPT corruption could explain this, though that seems unusual... Are you certain the system is running in UEFI mode? (This might not make much sense.)
It seems there are not many issues occupying the PCIe lanes. Just a 2080 TI and SATA drives. I can view the bios and select it, but I keep seeing an AORUS logo that keeps trying to load Windows without success. I've tested UEFI, disabled settings, and legacy modes—it doesn't seem to help.
Consider the simplest setup with the OS disk included. Run the Windows installation file and check the boot process. Attempt a repair if needed, or proceed with a fresh install. If reinstalling isn't possible, let me know your situation. Have you reached out to Gigabyte for assistance?
