If you have a removable SSD (M.2 or 2.5"), open the bottom panel and ensure the SSD is firmly seated.
Look for bent pins, dust, or loose screws.
Enter BIOS/UEFI
Restart the laptop and press F2 repeatedly when the Dell logo appears.
Check “Storage” or “Drives” → See if the SSD is listed.
If not listed, try:
Load BIOS defaults → Exit → Load Defaults → Save.
Change SATA Operation from RAID to AHCI (or vice versa), then save and restart.
If it shows up here but not in Windows → your issue is likely OS or driver related.
Update BIOS & Storage Drivers
Go to Dell’s official support page → enter your Service Tag Download and install Latest BIOS update. Intel Rapid Storage Technology driver (if applicable) Chipset drivers.
Test with Diagnostics:
Restart and press F12 → select Diagnostics.
Dell’s hardware test will check the SSD.
If it fails → the SSD is faulty.
If it passes → the problem is software-related.
Try an External Adapter
Remove the SSD and connect it to another PC using an M.2/2.5” to USB adapter.
If detected there → the laptop’s slot or settings are the issue.
If not detected → the SSD is likely dead.
Pro Tip:
On some Dell Inspiron models, switching SATA mode from RAID to AHCI after Windows install requires a safe boot tweak, or you’ll get a blue screen.
