The “Boot Device Not Found” error typically indicates that the computer’s BIOS (Basic Input/Output System) cannot locate a bootable device from which to load the operating system. 

In the boot process of a computer, the boot device holds the essential files and instructions necessary to load the operating system and initiate the user interface. This boot device is typically a hard drive, SSD (Solid State Drive), or USB drive containing the operating system’s files. 

When you power your computer, the BIOS is critical in initializing hardware components and locating the boot device to start the operating system. However, when the BIOS fails to find a suitable boot device, it triggers the “Boot Device Not Found” error, leaving the user unable to access their system.

Boot device not found error codes

Some manufacturers can specify when the boot device is not found with error codes instead of only displaying a message. Here are some manufacturers with their codes:

  • HP: Hard Disk 3F0
  • Dell: No bootable devices found
  • Lenovo: Default Boot Device Missing or Boot Failed
  • Acer: No bootable device
  • Asus: Reboot and select proper boot device

How to fix the boot device not found error message

To fix the boot device not found error, you can follow the next solution steps on your own. However, if you are not confident about how to perform a task, contacting an expert is the best way to fix the issue and prevent data loss.

Here are 8 solutions you can try to solve the issue:

Checking hard drive connections

Hard drive connections play a critical role in ensuring that your computer can boot properly. If the SATA or power cables connecting the hard drive to the motherboard or power supply are loose or improperly connected, the hard drive may not be detected by the computer during the boot process. This can result in the “boot device not found” error.

Physical damage to the SATA or power cables, such as fraying or bending, can also interfere with the proper connection between the hard drive and the motherboard or power supply.

  1. Shut down your computer completely and disconnect the power cord from the power outlet to prevent any electrical accidents. If possible, remove the battery.
  2. Open the computer or laptop to access the internal components.
  3. Ensure that both the SATA data cable and the power cable are securely connected to the hard drive and the motherboard.
  4. Examine the SATA and power cables for any signs of damage, such as fraying, bending, or broken connectors. If you notice any damage, replace the cables with new ones.
  5. Close the computer or laptop reconnect the power cord to the power outlet and power on your computer. 
  6. Turn the device on and check if the “boot device not found” error persists during startup. 

Verifying BIOS settings and boot order

Verifying BIOS settings and boot order is crucial in fixing the “boot device not found” error. That’s because the BIOS (Basic Input/Output System) controls the initial startup process of your computer and determines which device to boot from. If the BIOS settings or boot order are incorrect, your computer may attempt to boot from the wrong device, leading to the error message.

The boot order in BIOS determines the sequence in which your computer attempts to boot from different devices. By verifying the boot order, you can ensure that the hard drive is listed as the first boot device. Sometimes, changes in BIOS settings or firmware updates can inadvertently alter the boot order or settings, causing boot-related issues. 

  1. Restart your computer and access the BIOS setup utility during the startup process. The key or key combination to enter BIOS varies depending on your computer’s manufacturer but is commonly Esc, F2, F10, or Del. 
  2. Once in the BIOS setup utility, navigate to the “Boot” or “Boot Order” section using the arrow keys on your keyboard.
  3. Review the boot device order list to ensure that the hard drive containing the operating system is listed as the first boot device. If it’s not, use the appropriate key (usually F5 or F6) to move the hard drive to the top of the boot order list.
  4. After verifying and adjusting the boot order, save the changes by selecting the option to “Save and Exit” or pressing the corresponding key (often F10). Confirm the changes and exit the BIOS setup utility.
  5. Allow the computer to restart and boot up normally. Check if the “boot device not found” error persists. 

Running hardware diagnostics

Hardware diagnostics tests various components of your computer, including the hard drive, memory (RAM), processor, and other essential hardware components, to check for any failures or issues. 

Running hardware diagnostics can help fix the “no boot device found” issue by identifying any underlying hardware problems that may be causing the error. 

Refer to your computer’s user manual or visit the manufacturer’s website to find instructions on how to run hardware diagnostics specific to your computer model. Some manufacturers provide built-in diagnostics tools accessible during startup or through specialized software.

Pay close attention to any error messages or codes provided by the diagnostics tool, as these can help pinpoint the specific hardware component that may be causing the issue.

If the diagnostics tool detects any hardware failures or errors, take appropriate action to address the issues. This may involve replacing faulty hardware components, such as a failing hard drive or defective memory module. 

Performing a system restore 

If the issue started recently after a software change or update, consider performing a system restore to revert the system to a previous working state.
