“No Bootable Device” is the wording Acer and Lenovo laptops typically use when the BIOS can’t find an operating system to load. It’s the same fundamental issue as “No Boot Device Found” on HP machines or “Boot Device Not Found” on Dells — different brand, same problem.

What’s actually happening

When you press the power button, your computer runs through a startup checklist. One step is “find a drive that has an operating system installed.” If the BIOS gets through every connected drive without finding one, it shows this error and stops.

That can happen for a few different reasons:

  • The drive is fine but the BIOS is looking at the wrong device first
  • The drive has come loose physically (more common than you’d think)
  • The drive has failed
  • The boot files on the drive are corrupted

Free things to try

Unplug all USB devices. A flash drive, SD card, or even a phone plugged in for charging can confuse the boot order. Unplug everything except your keyboard and mouse and restart.

Check BIOS boot order. Press F2 (most Lenovo and Acer models) during startup to enter BIOS. Find the Boot section and make sure the main drive — usually labeled with a brand like Samsung, WD, or “Windows Boot Manager” — is at the top of the list.

Verify the drive is detected. While in BIOS, find the Storage or Information page. If you see your drive listed, the hardware is alive. If you don’t, the drive may need to be reseated or replaced.

Lenovo-specific: the OneKey Recovery angle

Some older Lenovo laptops have a small recovery partition that can show this error if the main partition table gets corrupted. We’ve fixed a number of these by repairing the boot record without losing user data — worth knowing before you write the laptop off.

Acer-specific: F12 to choose another boot device

Press F12 at startup on most Acer machines to bring up a one-time boot menu. If your drive shows up here, the drive is detected and the issue is the boot priority list. If it doesn’t show, the drive isn’t being seen by the BIOS at all.
