I just finished my first custom PC build and everything seems to power on normally, but the Windows installer does not show my NVMe SSD as an available installation drive. The drive is a 1TB TeamGroup MP44Q PCIe 4.0 NVMe M.2 SSD installed in a Gigabyte B550M Gaming X WIFI6 motherboard. I have reseated the SSD several times, but the installer still cannot find it. I'm not sure whether the drive appears in BIOS or what settings I should check. What is the best way to determine whether this is a BIOS setting, an installation-driver issue, a faulty SSD, or a motherboard problem?

If the drive is visible in BIOS but missing from Windows Setup, check that the system is using UEFI boot mode with CSM disabled. Also look for storage settings such as SATA mode or AMD RAID. Unless you intentionally enabled RAID, use the normal AHCI configuration. The fact that there are no SATA cables does not prevent these settings from affecting storage detection.
Updating the motherboard BIOS is worth considering if the firmware is old, especially with newer hardware. Before doing that, verify the M.2 slot is enabled and inspect the connector for damage. If the SSD remains invisible in BIOS after trying the supported slot and updated firmware, the most likely possibilities are a defective SSD or motherboard, and testing the parts separately is the fastest way to identify which one.
A storage-controller driver may be needed if RAID mode is enabled, but loading random files from the Windows USB usually will not help. Only use the correct driver package for the motherboard and select the folder containing the actual driver files. If the SSD is not present in BIOS, focus on hardware detection first rather than Windows Setup.
I tried using the Load Driver button, but browsing files on the USB just returns me to the drive-selection screen and the SSD still does not appear.
First check whether the SSD is detected in BIOS/UEFI. If it does not appear there, Windows drivers will not fix the problem. Power down, reseat the drive carefully, confirm it lies flat and is secured with the correct standoff and screw, then try the other compatible M.2 slot. If neither slot detects it, test the SSD in another computer or USB NVMe enclosure if possible. That will help distinguish a bad drive from a motherboard issue.
I’ve reseated it several times and it is sitting flat, but I’ll check both BIOS and the other slot. The lower slot seems like it may not fit the drive, though.
I tried changing the settings suggested by various guides, but I’m not completely sure which options are currently enabled.
