Understanding these common causes of boot errors can help you troubleshoot and resolve the Windows Stop Code Inaccessible Boot Device Error.

Sometimes the best way to solve a problem is to stop trying to fix it.

Strategies for Recovering from Boot Errors

  • Access the BIOS by restarting your computer and pressing the designated key (often Del or F2) to enter setup.
  • Locate the Boot Order or Boot Sequence settings and ensure that the correct drive (usually the C: drive) is set as the first boot device.
  • Save the changes and exit the BIOS, then restart your computer to see if the error is resolved.

Run Automatic Repair

  • Insert your Windows installation media (such as a USB drive or DVD) and restart your computer.
  • Choose the option to boot from the installation media and select Repair your computer.
  • Follow the prompts to run Automatic Repair, which will attempt to fix any boot-related issues automatically.

Check for Disk Errors

  • Open Command Prompt as an administrator by searching for “cmd” in the Start menu, right-clicking on it, and selecting Run as administrator.
  • Once in Command Prompt, type chkdsk /f /r C: and press Enter to check for and repair any disk errors on the C: drive.
  • Allow the process to complete, then restart your computer to see if the error is resolved.

Verifying Boot Disk Connection and Accessibility

To verify the boot disk connection and accessibility, start by checking the physical connections of the boot disk, ensuring that it is properly connected to the motherboard and power supply. If using a USB flash drive or external hard drive as the boot disk, try connecting it to a different USB port to rule out any issues with the port.

Next, access the BIOS or UEFI settings to confirm that the boot disk is recognized by the system. This may involve checking the boot order to ensure that the correct drive is selected as the primary boot device.

If the boot disk is recognized in the BIOS or UEFI settings, but you are still encountering the Inaccessible Boot Device error, you may need to use Windows Preinstallation Environment (WinPE) to access the Command Prompt and run diagnostic tools to check the disk’s file system integrity.

Using the Command Prompt, you can also use the diskpart tool to verify the disk’s partition structure and file system. Additionally, you can use commands such as chkdsk to check for and repair any file system errors.

If the boot disk is not accessible, you may need to connect the disk to another computer to perform data recovery or repair the file system.

By verifying the boot disk connection and accessibility, you can address issues that may be causing the Inaccessible Boot Device error in Windows.

When you reach a dead end, it’s time to stop and reassess your approach.

Integrity Checks for Boot Configuration Data

To resolve the Windows Stop Code Inaccessible Boot Device error, it is important to perform integrity checks for the Boot Configuration Data (BCD). This can be done by using the built-in Windows tool called “bootrec.”

First, you will need to access the Windows Recovery Environment. This can be done by inserting a Windows installation media such as a USB flash drive or a DVD, and then booting from it. Once in the Windows Recovery Environment, select the “Repair your computer” option.

Next, open a Command Prompt by selecting “Troubleshoot” > “Advanced options” > “Command Prompt.” In the Command Prompt, type the following commands:

bootrec /scanos
This command will scan for Windows installations on the computer and display the results.

bootrec /rebuildbcd
This command will rebuild the BCD based on the scan results.

After running these commands, restart the computer and see if the issue has been resolved. If the error persists, it may be worth considering other troubleshooting steps such as checking the hard disk drive for errors or performing a system restore.
