Have an Asus GU502LU (i7-10750H, 16gb, 1660Ti) that I got not long ago. I decided to add a WD Blue 1TB M.2, besides the 516gb M.2 that came with the system. The issue is that the WD does not show in device manager, disk management, or in the BIOS. In the BIOS (which is updated), there are only two options under SATA Config: AHCI and Intel RST with Optane. Selecting AHCI gives me a BSOD saying INACCESSIBLE_BOOT_DEVICE. I'm not sure what else to do or try to get this drive to work.
