A missing SSD in BIOS is almost never a dead SSD. It is usually seating, a protocol mismatch with the slot, or a storage-mode setting. Check them in this order before you think about returns.
You fitted the drive, powered on, and the BIOS storage list is empty — or Windows setup says no drives found. Stay calm and work the list: physical seating first, then slot compatibility, then BIOS settings. Each step below rules out one family of causes, and the drive itself is the last suspect, not the first.
Power off, charger out, battery disconnected (same safety order as the swap). Remove the SSD and fit it again: a 2.5-inch drive must slide fully onto its SATA connector — a half-seated connector is the number one cause of a missing drive. An M.2 stick goes in at a shallow angle, then presses flat; make sure it sits on the standoff and the end screw holds it without bending it. A stick screwed down while slightly raised at the connector end will not make contact.
An NVMe drive in an M.2 SATA-only slot is not detected at all — no error, just absence. The same applies in reverse on the rare NVMe-only slot. This is a specification question, not a settings question: check your laptop model's storage specification. If the protocols do not match, no BIOS setting will fix it — the drive must be exchanged for the type the slot supports.
Many Intel laptops ship with the storage controller in RST / RAID mode. Two different problems hide here. On a fresh install, Windows setup may show no drives until the Intel RST driver is loaded from a USB stick — a setup-screen issue, not a BIOS issue; the BIOS usually sees the drive fine. With a clone, keep the mode exactly as it was on the old drive: switching between RST and AHCI after cloning commonly ends in an INACCESSIBLE_BOOT_DEVICE blue screen, because Windows was installed against the other mode's driver. Only change modes deliberately, and know that converting an existing Windows between modes needs preparation, not just a BIOS toggle.
On older machines, a Legacy / CSM boot setting can hide an NVMe drive from the boot list — early BIOS versions could only boot NVMe drives in pure UEFI mode. Set boot mode to UEFI and, if the drive appears in storage but not in boot order, look for the drive's own entry or Windows Boot Manager after an install exists. Secure Boot rarely blocks drive detection itself, but a BIOS update from the manufacturer is worth checking on models from the early NVMe years — some gained proper NVMe support only in later BIOS versions. Update BIOS carefully, on charger power, and only from your model's official page.
If the slot protocol matches and reseating changed nothing, test the SSD in another machine or a USB enclosure: if it appears there, the drive is fine and the laptop slot or its settings are the story; if it appears nowhere, you may genuinely have a dead-on-arrival drive — they are uncommon, but they exist, and that is what the return window is for. Do not keep forcing a suspect drive through repeated power cycles.

▶️ Watch Full VideoThis is the classic Intel RST situation: the BIOS detects the drive, but the Windows installer lacks the storage driver to see it in RST/RAID mode. Either load the Intel RST driver during setup from a USB stick, or switch the BIOS storage mode to AHCI before a fresh install. For a cloned system, prefer loading the driver — changing mode breaks the clone's boot.
Usually not. A blank drive has nothing bootable on it, and many BIOS versions only list drives in boot order once they contain a boot loader. Install Windows (or finish the clone) first — the drive then appears as Windows Boot Manager. Judge detection by the storage/device list, not the boot list.
On some early-NVMe-era laptops, yes — manufacturers shipped fixes for specific drive compatibility in later BIOS versions. It is worth checking your model's BIOS release notes for storage mentions. Apply updates only from the official support page, with the charger connected, and never interrupt one.
