How to Fix Boot Device Not Found Windows 10
Boot device not found errors in Windows 10 are like those pesky hiccups that always seem to come at the worst possible times. But don’t worry, fixing it is actually quite straightforward. You’ll need to check your BIOS settings, possibly reset your BIOS, and ensure your hard drive is properly connected. These steps will get your computer back on track in no time.
How to Fix Boot Device Not Found Windows 10
In this section, we’ll go through the steps to fix the boot device not found error in Windows 10. By the end of these steps, your computer should successfully boot up without any problems.
Step 1: Enter BIOS Settings
First, restart your computer and press the designated key (often F2, F10, or DEL) to enter the BIOS settings.
This step is crucial because the BIOS manages system settings and startup processes. You need to access it to check if the boot order is correctly set.
Step 2: Check Boot Order
Once inside the BIOS, go to the Boot tab and ensure your hard drive is set as the primary boot device.
Sometimes the boot order gets altered, causing the system to look in the wrong place for the operating system. Setting the hard drive as the primary boot device corrects this issue.
Step 3: Save and Exit
After adjusting the boot order, save your changes and exit the BIOS.
Saving changes ensures that the new settings will take effect the next time your computer restarts. Usually, there’s a key (like F10) that saves changes and exits.
Step 4: Check Hard Drive Connection
Turn off your computer and open the case. Ensure the hard drive cables are securely connected.
Loose or improperly connected cables can prevent the computer from detecting the hard drive. Make sure both the power and data cables are firmly connected.
Step 5: Reset BIOS to Default
If all else fails, restart your computer, go back into the BIOS, and find the option to reset to default settings.
Resetting the BIOS can resolve any misconfigurations that might be causing the boot device error. This option is often found in the Exit menu.
After completing these steps, your computer should boot up without showing the "boot device not found" error. If the problem persists, it may be a sign of a failing hard drive or motherboard issue.
