Drive Missing in BIOS Too the Dead or Disconnected Drive Test
The drive is missing in BIOS itself — which means every software fix is a waste of time until the hardware answers. This split-test separates a loose cable from a dead drive in about fifteen minutes.

There is one hard rule in drive troubleshooting: if the BIOS cannot see the drive, Windows Setup never will. No driver, no DiskPart command and no BIOS mode setting fixes a drive the firmware itself cannot detect. When the storage page in BIOS is empty, stop working on software and run this physical split-test in order — cable, slot, seating, and finally the drive itself.
BIOS — Main / Storage information page
SATA Port 1 ............ Not Present
M.2 Slot 1 ............. Empty
Windows Setup reads this same hardware list.
If it is empty here, it will be empty there too.
The BIOS view that settles the argument. A drive missing here is a connection or hardware problem, full stop.

Reseat the Drive and Check the Cables
Power the PC fully off and unplug it. On a laptop, remove the charger and hold the power button for ten seconds
For a 2.5 inch SATA drive: reseat both cables — data and power. A SATA data cable that is half a millimetre loose is the classic cause
Try a different SATA data cable and a different SATA port on the motherboard — cables fail far more often than drives do
For an M.2 drive: remove it, check the gold contacts are clean, reinsert it fully at a slight angle until it seats, and refit the screw — an under-seated M.2 is invisible
On laptops, check any ribbon or interposer cable between the drive bay and the board; these work loose in transit

Check the M.2 Slot Type Trap
M.2 is a shape, not a promise. Some slots accept only SATA-protocol M.2 drives, others only NVMe, and many budget laptops have one of each behaviour per slot. An NVMe drive in a SATA-only slot will never appear in BIOS, and nothing is actually broken. Check the laptop or motherboard manual for the slot specification and try the other slot if one exists. The same applies in reverse for a SATA M.2 drive in an NVMe-only slot.

Prove the Drive on Another Machine
Connect the suspect drive to a second PC, or put it in a cheap USB enclosure or adapter
If the second machine's BIOS or Disk Management sees it, the drive lives — the fault is in the first PC's port, cable or board
If no machine sees it anywhere, the drive's controller is dead
For a spinning hard disk, listen as well: repeated clicking, beeping, or total silence with no vibration all point to mechanical or board failure inside the drive.
🔴 Honest note: a drive that no BIOS can see and that holds data you cannot lose is a data recovery lab job — do not keep power-cycling a clicking drive, because every attempt can make recovery harder. If the data is replaceable, replace the drive; a new SSD costs less than one hour of guessing.
🎥 Watch the Complete Fix in the Video
Watch the video after the hardware checks — it covers the setup-side fixes for drives the BIOS can see.
Can Windows Setup see a drive that BIOS does not show
No. Windows Setup builds its drive list from the same hardware the firmware detects. If the BIOS storage page says Not Present or Empty, setup will show an empty list no matter which driver you load. Fix the physical side first — cables, seating, slot type — or confirm the drive is dead.
My NVMe drive worked in my old laptop but not the new one
Most likely a slot protocol mismatch: M.2 slots can be SATA-only, NVMe-only, or both, and the shape is identical. An NVMe stick in a SATA-only slot is electrically invisible. Check the new laptop's manual for the slot specification, or try the second M.2 slot if it has one.
The drive clicks repeatedly and BIOS does not list it — is the data gone
Clicking means the heads cannot read the drive's own service data — a mechanical failure. Power it off and stop retrying; repeated attempts can damage the platters further. If the data matters, a professional recovery lab is the only realistic route. If it does not, the drive is finished and should be replaced.
