Encountering the "Inaccessible Boot Device" error on Windows 11 can be frustrating, but you can resolve it with a few straightforward steps. First, restart your computer and access the BIOS settings. Then, check and adjust your boot order. Next, boot into Safe Mode and update or uninstall faulty drivers. Finally, run some built-in Windows troubleshooting tools to fix any remaining issues.

Steps to Fix Inaccessible Boot Device on Windows 11

Before we begin, these steps will help you boot back into your Windows 11 system without hitting the "Inaccessible Boot Device" error. By the end of this guide, your computer should boot normally.

Step 1: Restart Your Computer and Access BIOS

Power off your computer, turn it back on, and press the designated key (like F2, F12, Del, or Esc) to enter BIOS.

Restarting and entering BIOS is essential because it allows you to reorder your boot sequence and ensure your primary hard drive is set to boot first. Sometimes, this simple fix resolves the issue.

Step 2: Check and Adjust Your Boot Order

In BIOS, navigate to the Boot menu and ensure your primary hard drive is set as the first boot device. Save the changes and exit.

Setting the primary hard drive as the top priority ensures your computer is trying to boot from the correct device. If another device is listed first, it might cause the "Inaccessible Boot Device" error.

Step 3: Boot into Safe Mode

Restart your computer, hold the Shift key, and click Restart. Then, navigate through the Advanced Options to boot into Safe Mode.

Booting into Safe Mode is crucial because it starts Windows with a minimal set of drivers and services. It can help you identify and fix issues without interference from other software.

Step 4: Update or Uninstall Faulty Drivers

Once in Safe Mode, open Device Manager, find any devices with a yellow exclamation mark, and either update or uninstall their drivers.

Faulty or outdated drivers can often cause the "Inaccessible Boot Device" error. Updating or uninstalling them ensures your system is using compatible and functioning drivers.

Step 5: Run Built-in Troubleshooting Tools

Open Command Prompt as an administrator and run commands like "chkdsk /f /r" and "sfc /scannow" to check and repair disk and system file errors.

These commands are powerful tools that scan your hard drive and system files for errors and repair them. They can resolve issues that might be causing the boot error.

After completing these steps, your computer should boot normally without displaying the "Inaccessible Boot Device" error. You’ve addressed the common causes and performed necessary troubleshooting.
