Many Windows users often encounter the Inaccessible Boot Device error. This issue usually arises from problems with the boot process, preventing the system from loading correctly. It can be frustrating because it often leads to an unbootable system and potential data loss. The Inaccessible Boot Device error is a prevalent issue on Windows that leads to the Blue Screen of Death (BSOD). Luckily, there exist do-it-yourself approaches to resolve this.
What is a Boot Device
Before we discuss fixing this error, let’s first understand what a boot device is. A boot device is any hardware or software that helps your computer start up and load the operating system (OS). Common boot devices include hard drives, solid-state drives, and USB flash drives. The boot device must be formatted with a file system compatible with Windows, such as NTFS or FAT32.
What is the Cause of the Inaccessible Boot Device Error
The inaccessible boot device error in Windows can occur due to various factors. Some of the typical causes include:
- Outdated or corrupt drivers: If your hard disk or SSD drivers are outdated or corrupted, the system might not recognise the boot device.
- Damaged hardware: Physical damage to the hard disk, SSD, or other components can prevent the system from accessing the boot device.
- Incorrect BIOS configuration: Misconfigured BIOS settings, like boot order or storage configuration, can trigger this error.
- Recent software installations: New software or updates may conflict with existing system files, causing boot issues.
- Malware infection: Viruses or malware can modify critical system files, leading to an inaccessible boot device error.
- File system errors: This issue can be caused by file system corruption, which is often caused by improper shutdowns or disk errors
Steps to Resolve the Inaccessible Boot Device Error
There are several methods to fix the inaccessible boot device error in Windows. If the error prevents you from accessing your system normally, you can boot into Safe Mode and apply one of the following solutions.
-
Check and Update Drivers
If outdated or corrupt drivers are causing the issue, you can update them using these steps:
- Reboot your computer and repeatedly press F8 to enter Safe Mode.
- In Safe Mode, access Device Manager and expand Disk drives.
- Right-click on each drive listed under Disk drives and select Update driver.
- Follow the on-screen prompts to conclude the update process.
- After updating all drivers, restart your computer and check if the error persists.
-
Run System File Checker (SFC)
The System File Checker tool checks and fixes system files that could trigger the inaccessible boot device issue. Here's how to execute it:
1. Access Safe Mode and press the Windows key + R to open the Run command.
2. Enter 'cmd' and press Ctrl + Shift + Enter to launch an elevated Command Prompt.
3. In the Command Prompt, input 'sfc /scannow' and press Enter to start the scan.
4. After the scan finishes, reboot your PC and verify if the error is still there.
-
Use System Restore
If you just installed new software or updates, a system restore may help resolve the issue. This will revert your system to a previous state where it was working correctly.
- In Safe Mode, go to Control Panel and click on System and Security.
- Select System, then click on System Protection in the left pane.
- Choose System Restore and follow the instructions to choose a restore point.
- Once the restore is finished, restart your computer and check if the error persists.
-
Check for Disk Errors
Corrupted file systems or disk errors can trigger the inaccessible boot device error. You can check and repair disk errors using the Check Disk tool.
To run a disk check in Safe Mode, follow these steps:
1. Launch an elevated Command Prompt.
2. Enter `chkdsk C: /f` (substitute "C" with your drive letter) and press Enter to initiate the scan.
3. Adhere to the on-screen instructions to plan a disk check for the next boot.
4. After the scan finishes, reboot your PC and verify if the issue remains. -
Check your computer's BIOS Settings
If misconfigured BIOS settings are the root cause of this error, you can fix it by changing a few settings.
- Reboot your computer and press the key indicated on the boot screen (usually F2 or Del) to enter the BIOS setup.
- Go to the Boot tab and confirm your hard disk or SSD is set as the primary boot device.
- If you have multiple disks, make sure the one containing the OS is set as the primary boot device.
- Save changes and exit BIOS.
- Restart your computer and review if it boots up without any error.
-
Perform a clean Boot
A clean boot involves starting Windows with only the essential drivers and startup programs. This approach helps resolve software conflicts that may lead to BSOD errors. To execute a clean boot, follow these steps:
- Press the Windows key + R to launch the Run dialogue.
- Enter `msconfig` and press Enter to access System Configuration.
- Navigate to the Services tab and pick the Hide all Microsoft services option.
- Disable all services, then move to the Startup tab and open Task Manager.
- Within Task Manager, turn off all startup programs by right-clicking on each one.
- Exit Task Manager, return to the System Configuration window, and click Apply.
- Reboot your computer and confirm if the problem remains.
