Laptop Model: Asus ROG Scar II, GL504GS.
OS: Windows 10 home (64bit)
BIOS Version: GL504GS.308
Disks: (C:) 256 SSD, (D:) 1 TB HDD
Yesterday windows prompted an update, when i shut down my laptop. The update started, and apparently was a BIOS update (Did not know windows update could force that). The update completes successfully, and restarts, then boots to windows. I quickly realize that the HDD (D:) is missing in windows, and only the (C:) SSD is showing. The HDD is not showing up in device manager, and it is not showing up in the BIOS. It is as if the HDD is not being registered at all by the laptop.
Help resolving this issue would be very much appreciated
