If you’re staring at a “boot device not found” error on your Windows 10 computer, it means your system can’t locate an operating system to boot from. This could be due to various reasons like incorrect BIOS settings or a malfunctioning hard drive. The good news? You can fix this yourself. Here’s a quick overview: Check and adjust BIOS settings, ensure your hard drive is properly connected, and use Windows recovery options if needed. Now, let’s dive deeper into each step.
How to Fix Boot Device Not Found Windows 10
This section will guide you through resolving the “boot device not found” error by troubleshooting BIOS settings, checking physical connections, and using Windows recovery tools.
Step 1: Enter BIOS Setup
Press the designated key (often F2, F10, or Delete) during startup to enter BIOS setup.
Accessing BIOS allows you to check if your hard drive is recognized. If your drive isn’t listed here, your computer won’t be able to boot from it. This is crucial for diagnosing the issue.
Step 2: Check Boot Order
Ensure that your hard drive is set as the first boot device.
If the boot order is incorrect, your computer might be trying to boot from a device without an operating system. Adjusting this setting could resolve the error instantly.
Step 3: Check Hard Drive Connection
Turn off your computer, open the case, and ensure the hard drive is properly connected to the motherboard.
Loose or disconnected cables can cause the system to fail to detect the boot device. Make sure all connections are secure.
Step 4: Use Windows Recovery Tools
Insert a Windows 10 installation media, boot from it, and select “Repair your computer” to access recovery options.
The recovery tools can help repair any corrupted system files that might be causing the boot device error. This could include running tools like Startup Repair or Command Prompt for advanced fixes.
Step 5: Check for Hard Drive Issues
Run a diagnostic test on your hard drive using tools available in BIOS or third-party software.
A failing hard drive can also be the culprit. Running a diagnostic test can help determine if the drive itself needs to be replaced.
After completing these steps, your computer should be able to boot up normally, or at least, you’ll have a better idea of what the problem might be.
Tips for Fixing Boot Device Not Found Windows 10
- Backup Your Data Regularly: Always keep a backup to avoid data loss in case of hard drive failure.
- Keep BIOS Updated: Updating BIOS can resolve compatibility and detection issues.
- Check for Physical Damage: Look for any visible damage to cables or ports.
