How to Fix Windows Server Error - 0x0000007B - INACCESSIBLE_BOOT_DEVICE

Windows Server users may encounter the dreaded error code 0x0000007B, also known as INACCESSIBLE_BOOT_DEVICE. This error occurs when Windows is unable to access the system partition during startup. It can be a frustrating issue, but there are several methods to fix it. In this article, we will explore the causes of this error and provide step-by-step solutions to resolve it.

Causes of the Error

The 0x0000007B error can be caused by various factors, including:

  • Corrupted or missing boot files
  • Incorrect BIOS settings
  • Faulty hardware
  • Outdated or incompatible drivers

Solutions to Fix the Error

1. Check BIOS Settings

One of the first things to check when encountering this error is the BIOS settings. Ensure that the boot order is set correctly and that the hard drive is recognized by the BIOS. If the settings are incorrect, adjust them accordingly and try to reboot the server.

2. Use Windows Recovery Environment

If the BIOS settings are correct, the next step is to use the Windows Recovery Environment (WinRE). To access WinRE, you will need to boot from a Windows installation media. Once in WinRE, you can use the following tools to fix the error:

  • Startup Repair: This tool can automatically fix boot-related issues.
  • Command Prompt: Use the command prompt to run the bootrec command, which can rebuild the boot configuration data (BCD).

3. Check for Faulty Hardware

Faulty hardware, such as a damaged hard drive or RAM, can also cause the 0x0000007B error. Run hardware diagnostics to check for any issues. If any hardware components are found to be faulty, replace them before attempting to boot the server again.

4. Update or Roll Back Drivers

Outdated or incompatible drivers can lead to boot errors. If you recently installed new hardware or updated drivers, try rolling back to the previous version. Alternatively, check the manufacturer's website for updated drivers that are compatible with your server's operating system.

5. Perform a Clean Boot

If the error persists, performing a clean boot can help identify any software conflicts that may be causing the issue. To perform a clean boot, use the msconfig utility to disable all non-Microsoft services and startup programs, then restart the server.

The Windows Server error 0x0000007B - INACCESSIBLE_BOOT_DEVICE can be a challenging issue to resolve.
