When you see this error message, it’s essential to understand its potential causes and explore the various solutions available to resolve it.

Possible causes of the error

Several factors can trigger the „Reboot and Select Proper Boot Device” error on a Windows 10 system. One common cause is a misconfiguration in the BIOS or UEFI settings. If your computer is set to boot from an incorrect or non-existent device, you’re likely to encounter this error.

Steps to fix the error

Resolving the „Reboot and Select Proper Boot Device” error requires a systematic approach. Here are some steps you can take to troubleshoot and fix the issue:

Check Boot Device Priority: Access your computer’s BIOS or UEFI settings and verify that the correct boot device is selected as the primary boot option. Ensure that the hard drive or SSD containing your operating system is properly recognized.

Verify Hardware Connections: Open up your computer’s case and inspect the connections between the hard drive/SSD and the motherboard. Ensure that all cables are securely attached and that there are no loose connections.

Run Startup Repair: Boot your system using a Windows 10 installation media (USB/DVD) and select the „Repair your computer” option. Navigate to Troubleshoot > Advanced options > Startup Repair. Follow the on-screen instructions to let Windows attempt repairs automatically.

Use Command Prompt: From the same Windows 10 installation media, access the Command Prompt in the Advanced options. Use commands like bootrec /fixmbr, bootrec /fixboot, and bootrec /rebuildbcd to repair the Master Boot Record (MBR) and boot configuration data.

Check Disk for Errors: Run the CHKDSK utility to scan and repair any errors on your hard drive or SSD. Open Command Prompt from the Advanced options and type chkdsk C: /f /r (replace C: with the drive letter where Windows is installed). Restart your computer after the scan completes.

Update BIOS/UEFI Firmware: Visit the manufacturer’s website to download and install the latest BIOS or UEFI firmware for your motherboard. Be cautious while updating firmware and follow the instructions provided by the manufacturer carefully.
