If you encounter the “Reboot and select proper boot device” error message, don’t panic. There are several solutions you can try to fix the issue. In this section, we will discuss the most common methods to resolve the problem.
- Check the boot order in BIOS: As we mentioned earlier, an incorrect boot order can cause the error message. To check and modify the boot order, you need to access the BIOS (Basic Input/Output System) settings. To access BIOS, restart your computer and press the designated key (usually F2 or Delete) during the boot-up process. Once you’re in the BIOS, navigate to the boot order menu, and make sure the bootable device (usually your hard drive or SSD) is listed first. Save and exit the BIOS, and restart your computer.
- Repair the boot sector: If the boot sector is damaged, you can repair it using the Command Prompt. To do this, you need a Windows installation disk or a bootable USB drive. Insert the installation disk or USB drive and restart your computer. Select the language, time, and keyboard options, and click on “Repair your computer.” Select “Troubleshoot” and then “Command Prompt.” In the Command Prompt, type “bootrec /fixboot” and press Enter. Then type “bootrec /fixmbr” and press Enter. Finally, type “bootrec /rebuildbcd” and press Enter. Restart your computer.
- Check the hard drive or SSD: A failed hard drive or SSD can cause the error message. To check if this is the case, you can run a diagnostic tool. Many hard drive and SSD manufacturers provide free diagnostic software that you can download and use. Run the diagnostic tool and check if there are any errors or bad sectors. If your hard drive or SSD has failed, you need to replace it.
- Check the SATA or power cables: If the SATA or power cables are loose or damaged, you can try reconnecting or replacing them. Turn off your computer and unplug it. Open the case and locate the cables connecting the hard drive or SSD to the motherboard. Make sure the cables are firmly connected and not damaged. If the cables are damaged, replace them with new ones.
The “Reboot and select proper boot device” error message can be frustrating, but with the right troubleshooting steps, you can fix the problem. By checking the boot order, repairing the boot sector, checking the hard drive or SSD, and checking the SATA or power cables, you can resolve the issue and get your computer running smoothly again. Remember to back up your important data regularly to avoid losing it in case of a hard drive or SSD failure.
