"Bootable device not found" means the computer could not start from the expected storage device. It does not automatically tell you whether the drive is dead, Windows is damaged, or the boot settings changed.

If the computer contains important files, avoid reinstalling Windows before checking storage health. A failing drive may still contain readable data, but repeated boot attempts and repair tools can reduce options.

Common causes

The internal SSD or hard drive may not be detected. The boot order may have changed after a BIOS reset. Windows boot files may be damaged. A loose storage connection, liquid damage or motherboard fault can also cause the same message.

On desktops, recent moves or upgrades can loosen cables. On laptops, storage may be soldered or hidden, making diagnosis model-specific.

Useful first checks

Take a photo of the exact message. If you know how to enter BIOS safely, check whether the storage appears, but avoid changing multiple settings. Do not initialise or format the drive if Windows recovery prompts appear.
