Identifying the Boot Error

Error Message on Dell Laptop

If your Dell laptop shows the message “no bootable device found,” it means your system is not starting properly. To troubleshoot this, press and hold the power button for about 10 seconds to turn it off completely. Then, unplug all external devices like mouse and power cables. Restart your laptop and continuously tap the F2 key as it powers on.

When the keyboard blinks, release the keys.
Press Ctrl + Alt + Delete together, then hit the F2 key again.

Once in the boot menu, check the boot sequence settings. Make sure the time and date are correct before selecting SATA operation and ensuring it is set to AHCI.

Initial Power Down

After checking the settings, look at the drive options. Make sure that both SATA 2 and any other required options are ticked. Apply the changes, and exit the menu to see if the issue is resolved. If not, you need to adjust other settings.

You can also try changing the boot sequence to Legacy mode. This can be done by selecting the hard drive option and ensuring it is at the top of the list. Verify that the Legacy option ROM is enabled and the Secure Boot setting is disabled. Apply your changes, exit, and reboot the system.

If the error persists, you may need to restore your BIOS factory settings. This action can reset all system settings but may resolve the boot issues. After restoring settings, check again if the laptop can boot up properly.

Preliminary Steps

Disconnecting External Devices

Before troubleshooting the error message on your Dell laptop, make sure to turn off your device properly. Press and hold the power button for about 10 seconds to shut it down completely. Once your laptop is off, remove all external cables. This includes any mouse, power, or other connected devices. After disconnecting all external devices, you can start the laptop again to see if the error persists.

Accessing BIOS Setup

Turn on your laptop. Press the F2 key repeatedly as soon as it powers on to access the BIOS setup. Keep an eye on the keyboard; it should blink if you are hitting the key at the right time. After entering the BIOS, check the boot sequence settings. Ensure the correct settings are selected.

Make sure the date and time are accurate. If they are not, update them within the BIOS. Next, look for the SATA operation setting under the system configuration tab. You want to ensure that AHCI is selected. Click on this option, apply the changes, and exit the BIOS. If issues persist, you may need to explore additional troubleshooting methods.
