BIOS未显示M.2插入设备
You're setting up your first PC and facing issues with your M.2 NVMe SSD not appearing in the system. Despite trying various steps like changing settings, resetting BIOS, and using a different HDD, it's still missing. It might help to double-check the physical connections and ensure the SSD is properly seated. Also, verify that the CMOS battery is functioning correctly and that the motherboard BIOS recognizes the device after resets.
I faced a similar issue once. I fixed it by inserting the m.2 in another slot—even if it wasn't the optimal one—and unplugging my hard drive. After that, I checked the BIOS and saw the m.2 listed. Honestly, I stopped using the hard drive afterward. Even after clearing the CMOS, make sure you do it correctly: remove all components from the back of your PC, disconnect everything, take out the battery and let it rest for 5 to 10 minutes (usually around 10 minutes), then reinsert the battery and power up again. P.S. When troubleshooting, it helps to plug in whatever you need first—like a monitor or keyboard, not peripherals like speakers or webcams.
I’d attempt to restore your BIOS to its standard configuration. Usually this can be achieved via the BIOS interface or by disconnecting the CMOS battery (if you plan to replace any components, make sure the device is off and disconnected from power). Once removed, wait until it’s completely inactive before placing it back in. After that, reinstall the CMOS battery. Either way, the BIOS should return to its original defaults. Occasionally I encounter issues with M.2 drives not appearing—this might stem from a BIOS adjustment. In your scenario, the drive could be improperly seated. Start by verifying the M.2 placement on the motherboard manual; sometimes the correct slot isn’t obvious at first glance. Adjusting to the proper slot can resolve detection problems before you tweak BIOS settings.
I finally changed my bios to the latest release, and the drive displayed correctly this time using RAID. I'm performing another CMOS reset to check for any effects. Additionally, I reinstalled the HDD, which also showed up in RAID.
