Reboot and Select Proper Boot Device

Ever turned on your computer and been greeted with the dreaded “Reboot and Select Proper Boot Device” error? It’s like your computer’s way of saying, “Hey, I’m lost! Help me find my way.” But don’t fret! This guide will walk you through the causes and solutions to get you back on track.

This error message is pretty severe and will prevent you from accessing your system. There can be a lot of different causes for it so hopefully one will work out for you.

What is the Error?

The “Reboot and Select Proper Boot Device” error occurs when your computer’s BIOS (Basic Input/Output System) cannot find the bootable device or the necessary files to start the operating system. This error can be alarming, but understanding its causes can help you troubleshoot and resolve it.

Common Causes:

Understanding the root of the problem is half the battle. Let’s dive into some common culprits:

  1. Incorrect Boot Order: The BIOS follows a specific sequence to check devices for bootable files. If this order is incorrect, the BIOS might look in the wrong place, leading to the error.
  2. Faulty or Disconnected Cables: Loose or damaged cables can prevent the BIOS from detecting the boot device. Think of these as the bridges that connect your computer’s brain (the motherboard) to its memory (the hard drive). If the bridge is broken, the connection is lost.
  3. Corrupted Boot Sector: Essential files required during the boot process can become corrupted, making them unreadable. This issue can vary in severity because hard drive corruption can be an early indication of a larger issue with the drive. You should immediately start backing up your data in case the drive is going to fail.
  4. Failed Hard Drive: Physical damage or wear and tear can render a hard drive unusable.
  5. Outdated BIOS: An outdated BIOS might not support newer hardware or might have bugs that cause the error.

Step By Step Solutions:

Now that we’ve diagnosed some of the possible problems, let’s roll up our sleeves and get to fixing!

  1. Checking Data Cables: Start simple. Ensure that the cables connecting your hard drive to the motherboard are secure. If they look damaged or frayed that’s a cause for concern (what caused that?) Most likely if the issue is with the cables it will be one that popped out or possibly a broken connector.
  2. Check Boot Order: Access the BIOS setup (usually by pressing keys like F2, F12, DEL, or ESC during startup) and ensure the boot order prioritizes the device containing your operating system. Make sure that your boot order settings have your primary hard drive at the top.
  3. Inspect Cables: Ensure all cables, especially those connected to the hard drive, are secure. If booting from an external device, check its connection.
  4. Run Diagnostic Tools: Many computer manufacturers provide diagnostic tools to check for hardware issues. Running these can identify and sometimes even fix problems.
  5. Update BIOS: If your BIOS is outdated, visit the manufacturer’s website to download and install the latest version.
  6. Reinstall or Repair the OS: If other methods fail, consider reinstalling or repairing your operating system. Remember to back up essential data before doing so.
  7. Repairing the Hard Drive: If you suspect your hard drive is the issue, start by backing up your data. Then you can use whatever hard drive repair tool you prefer (Scandisk, CHKDSK, etc.)

Using Windows Recovery Tools

Insert a Windows installation or recovery disk. Boot from it and select “Repair your computer.” Follow the prompts to repair any issues.

Preventive Measures

An ounce of prevention is worth a pound of cure, right?

Regular Backups

Always backup your data. It’s like taking photos of your favorite memories; you don’t want to lose them.

Updating BIOS/UEFI

Manufacturers release updates to fix known issues. Stay updated to avoid problems.

Avoiding Physical Damage

Treat your computer with care. Avoiding bumps and drops can prevent many issues.

Real-World Scenarios:

A user on Microsoft’s community forum mentioned encountering this error after updating to Windows 11 Version 22H2. After some troubleshooting, the user accessed the BIOS by repeatedly tapping the BIOS key and reset the settings, resolving the issue. Another user suggested checking if the hard drive is recognized in the BIOS and ensuring it’s properly connected.


Facing the “Reboot and Select Proper Boot Device” error can be daunting, but with the right knowledge and a bit of patience, you can navigate the issue like a pro. Remember, every problem has a solution. And now, you’ve got a toolkit full of them!

Whether you’re a seasoned tech enthusiast or a casual computer user, understanding the causes and solutions can save you time and stress. Remember always to keep backups of essential data and consult professionals if unsure about any steps.
