Introduction

This error typically occurs during the boot process of a computer and prevents it from loading an operating system. It indicates that the computer’s firmware (BIOS or UEFI) could not find a bootable device or media, such as a hard drive, SSD, or USB drive.

Causes of the Error

  • Faulty or disconnected hard drive
  • Corrupted or missing boot sector
  • Damaged or outdated BIOS or UEFI firmware

Troubleshooting Steps

1. Check BIOS/UEFI Boot Order

Enter the BIOS or UEFI settings (usually by pressing F2, F10, or Del during boot) and ensure that the primary boot device is set to the correct hard drive or SSD where the operating system is installed.

2. Reseat Hard Drive

Power down the computer, open the case, and firmly reconnect the SATA or NVMe cable to the hard drive. Ensure that the connections are secure and the drive is properly seated.

3. Perform System Diagnostics

Many computer manufacturers provide built-in hardware diagnostics tools. Run these diagnostics to check the status of the hard drive and other critical components.

4. Repair Boot Sector

Use a bootable Windows USB drive or recovery disk to access the Windows Repair Environment. Select “Startup Repair” to automatically scan and repair any boot sector issues.

5. Update BIOS/UEFI Firmware

Visit the manufacturer’s website for your computer’s motherboard and check for any available BIOS or UEFI firmware updates. Download and install the latest version.

6. Check Hardware Compatibility

If you have recently installed new hardware, such as a graphics card or RAM, ensure that it is compatible with your motherboard and operating system.

7. Reset CMOS

Locate the CMOS battery on the motherboard and remove it for a few minutes. This will reset the BIOS or UEFI settings to their default values. Replace the battery and restart the computer.
