It’s easy to understand the “Reboot and choose proper boot device” error. Restart your computer and select which hardware your system uses for booting up. What’s the best solution to this problem?
The “Reboot and choose the correct boot device in most cases, the error message that appears on the black screen just before Windows starts up is caused by one of these causes:
· Incorrect hard drive selection in BIOS
· Windows boot loader does not work correctly, or it is not detecting your hard drive.
· Hardware error on the hard drive
To solve an error, the first step is to find its root cause. Most mistakes can be corrected.
Cause of error: In the BIOS, an incorrect hard drive was selected
Often a weak BIOS battery or an incorrect BIOS setting is why your computer isn’t recognizing your hard drive, and your computer won’t start.
The BIOS (Basic Input Output System) is the only software permanently installed on your PC. This memory chip includes a program that recognizes the most important components of your computer and allows you to start the operating system from your hard disk, CD-ROM, DVD, or USB drive.
1. To make changes in the BIOS, you’ll need to press a certain key to access the BIOS setup during the booting process. The prompt will appear on the screen for most computers.
2. You can reset BIOS to its default settings in the BIOS Setup program. In most cases, this is sufficient.
3. If this doesn’t work, you can check the BIOS listing for the hard drives. A PC usually boots from the first hard disk. You can control the order that the BIOS Setup program searches for boot sectors on the drives. “Reboot and choose the proper boot device”OS not found error message could also indicate that your computer is not equipped with the operating system it needs to be booted.
4. The BIOS detects the attached hard drive automatically and enters the required hardware parameters. In most cases, this process works well. If the issue is not resolved, the BIOS will display the hard drive incorrectly, and Windows won’t recognize it. Many BIOS versions include a “custom type” on the hard drive that allows you to enter your hardware parameters. You can find them on the hard drive but not directly from the manufacturer’s specifications.
5. It is possible to set the system hard disk as the default boot drive in some BIOS versions and disable the optional graphic boot menu.
6. Save your BIOS settings after making the changes.
Reason for error: The Windows Boot Loader isn’t working correctly
If the BIOS has been set correctly, but the computer still displays the “reboot or select proper boot device” error during startup, it is possible to fix this. Windows system repair options can help you repair the boot loader.
1. Since this type of error means that the Windows 10 boot loader can no longer be found, boot your computer from a Windows installation DVD or a bootable USB drive containing the Windows installation files. These media contain advanced boot options, which allow you to fix the operating system and recover your data.
2. Select your language first, then click “Repair your Computer” on the next page. You don’t need to reinstall Windows.
3. On the next screen, click “Choose an Option” and “Troubleshoot.” You can also use this option to troubleshoot error messages if Windows is not starting.
4. You will be taken to a dialogue window that allows you to restore your computer to its factory settings. If all other repair options fail to help, this option is necessary.
5. For additional options to repair a Windows system that has been damaged, you can select “Advanced Options”. This will allow you to get it back up and running.
6. The Startup Repair tool is helpful if Windows won’t start because of the boot sector. This is a common problem.
Start Startup Repair and wait until it is finished. Disconnect the USB drive from the drive, then remove the Windows DVD and restart the computer.
Startup Repair will not resolve the problem of “reboot and choose the proper boot device.”
Startup Repair may not be able to fix the problem. If that is the case, Startup Repair may not be able to fix it. Write a new boot sector to your hard drive. This feature is available in Windows 8.1 and Windows 7
1. This method allows you to boot your computer using a Windows installation DVD. Select your language, then click “Repair my computer” on the next page.
2. Next, choose “Choose an Option” > “Troubleshoot”> “Advanced Options” -> “Command Prompt.”
3. Now, type the following command: bootrec /fixmbr
4. This command creates a new master boot file on the hard drive. Next, type bootrec /fixboot
5. This command creates a new boot section to the disk to replace any overwritten boot loader with an older Windows version.
6. To close Command Prompt, choose exit and then select Restart in the Repair Options. Restart from your hard drive and not the Windows DVD.
Reason for error: A hardware problem has occurred on the hard drive
A hardware problem can make your hard drive sound more serious than it is. Sometimes, the problem might be as simple as a hardware error. Defective connecting cables. Nearly all modern computers use a SATA interface for connecting hard drives. These cables don’t last forever. Over time, the tiny connections can become corroded or dusty. Even the smallest kinks in the cable could cause your computer not to recognize the attached hard drive.
1. Disconnect the power supply from your computer. Next, disconnect the SATA cable between the motherboard and hard drive. Finally, wipe the contacts clean with an alcohol wipe. Then reconnect the cable and restart the computer. This will often solve the problem. You can also try another SATA cable.
2. After you have ruled out SATA cables being the culprit, take the hard drive off the computer and turn it on again. It is possible to use a hard drive with a boot sector defect that is not hardware related.
3. After installing the hard drive as a secondary drive on the other computer, you will need to change the boot order in your BIOS to ensure that the computer continues to boot from the Windows operating system’s hard drive.
4. Windows will startup, and the second drive is displayed in the File Explorer. This happens as long as the file system of the drive is still being recognized by Windows.
5. Right-click the drive from the File Explorer and select “Properties”. Next, go to the “Tools” tab. Click “Check.”
6. Then, you can choose which checks you wish to run. You can run a full scan and recover any bad sectors.
7. Then, back up as much data as you can from the hard drive. Important data should not be stored on a hard drive that has a defect in its hardware. Errors will probably occur in other sectors.
8. If the File Explorer repair tool is not working, right-click on the Windows logo in your taskbar and run Command Prompt. Then you can repair the hard disk with the chkdsk command. This will give you an excellent chance to recover data.
Once you have successfully backed up your data, replace the hard drive.
