Computer says no boot device found

Share it

Certainly! When your computer displays a “No bootable device found” error, it can be quite alarming. This message indicates that the BIOS or UEFI firmware is unable to locate a drive with the necessary tools to boot an operating system. But fear not—I’ve got you covered with a step-by-step process to troubleshoot and resolve this issue.

Understanding Boot Issues

Before we dive into the steps, let’s understand the boot process and recognize the specific error messages. When your computer fails to find a bootable device, it’s crucial to pay attention to any accompanying error codes or instructions. Here’s an overview of the boot process:

 1. Power On and POST (Power-On Self-Test):

    • When you power on your computer, the BIOS or UEFI firmware initializes and performs a self-test.
    • It then searches for a bootable drive containing either the Master Boot Record (MBR) or the System Partition (for UEFI systems).

  2. Boot Order:

    • The boot order in the BIOS/UEFI determines the sequence in which drives are checked.
    • Incorrect boot order settings can lead to the system overlooking the intended bootable device.

  3. Components in the Boot Process:

Now, Let’s Fix It Step by Step:

 1. Perform a Hard Reset:

  • Sometimes, rebuilding the connection between hardware and BIOS can resolve issues.
  • To perform a hard reset:
  • Turn off your device by holding the power button for a few seconds.
  • Restart your computer and keep pressing the appropriate key (usually F2) to access the BIOS settings.

 2. Reset Your Hard Drive:

  • Try resetting the hard drive:
  • Access the BIOS settings (as mentioned above).
  • Look for an option related to resetting the hard drive.
  • Follow the prompts to reset it.

 3. Run CHKDSK Command:

  • Open Command Prompt as an administrator.
  • Type chkdsk /f and press Enter.
  • This command checks and fixes any bad sectors on your hard drive.

  4. Reset BIOS Default Settings:

  • In the BIOS, look for an option to reset to default settings.
  • Confirm the changes and reboot.

  5.Boot from Bootable Media and Rebuild MBR:

  • Create a bootable USB drive with Windows installation files.
  • Boot your PC from this USB drive.
  • Use recovery tools to repair or rebuild the MBR.

  6. Consider Resetting Your PC:

  • If all else fails, consider resetting your PC to factory settings (backup your data first).

“Remember, patience and attention to detail are key during troubleshooting. Follow these steps, and hopefully, your system will be up and running smoothly again! 😊🔍🖥️”
