B450i fails to detect M.2 device initially, then successfully identifies it later.
B450i fails to detect M.2 device initially, then successfully identifies it later.
I previously set up a system with those components and it worked well for years. I transferred it from an open case to an NZXT H210i to give to my nephew. Now I encounter a recovery error (0xc00000e9) when starting up. After checking the BIOS, only the SATA drive appears, not the M.2 drive I usually use. I expected that issue to cause the error, but I’m getting a Windows recovery prompt instead. I’ve tried desoldering the USB and SATA headers on the motherboard, but it doesn’t help. I’ve updated the BIOS and plan to reinstall Windows from the SATA drive, then remove the M.2 drive to test. Is there anything missing? I’m aware of settings that can restrict bandwidth for USB or M.2 devices, but I don’t see specifics for this case. Your help would be really appreciated!
It seems the M.2 storage device isn't being detected by the motherboard. Possible causes include a defective drive, a faulty M.2 slot on the board, or problems with the cables or connectors. You might want to verify the BIOS configuration to ensure the M.2 is listed as the main boot option. If it doesn’t appear in the BIOS, the hardware may be faulty and you could need to replace either the drive or the motherboard. Also inspect the cables and connectors—confirm they’re firmly attached, as loose connections can lead to this issue. Should you go through these checks and still face recognition problems, consider reinstalling Windows on the SATA drive to isolate whether the issue lies with the M.2 unit or the system. In short, the problem could stem from a bad drive, motherboard compatibility, or cable issues. You can try adjusting BIOS settings, securing cables, and performing a fresh Windows setup to resolve it. Let me know if you need more details!
