“No Bootable Device Found” – What It Means and How to Fix It

Few things are more alarming than turning on your computer and seeing the message: “No Bootable Device Found.”

This error means your system can’t locate an operating system to start from, leaving you stuck at startup. But don’t panic—this is often fixable with a few steps.

What It Is:

Your computer is trying to start up (or “boot”) but can’t find a drive that has a valid operating system (like Windows, Linux, or macOS). As a result, it halts and shows an error on screen.

No boot able device found - how to fix it

Common Causes:

  • 🛠️ Disconnected or Failed Hard Drive: The internal drive may have come loose (especially if the computer was dropped or opened recently), or the drive may have failed entirely.

  • ⚙️ Incorrect BIOS/UEFI Settings: If the boot order is wrong, the system might try to boot from the wrong device—like an empty USB port or network device.

  • 🔄 Corrupted Bootloader or OS Files: Sometimes system files are damaged due to a failed update or improper shutdown, making the drive unreadable during boot.

  • 🔌 Loose or Damaged SATA/Power Cables: Physical connections from the motherboard to the hard drive might be loose or damaged.

How to Fix It:

1. Check the Boot Order in BIOS/UEFI

  • Restart the computer and enter BIOS/UEFI (usually by pressing F2, F10, DEL, or ESC during startup).

  • Navigate to the Boot menu.

  • Ensure your system drive (e.g., SSD or HDD) is listed first in the boot sequence.

2. Reconnect or Reseat Internal Drives

  • Power off your PC and unplug it.

  • Open the case (if it’s a desktop) or access the drive bay (for laptops).

  • Ensure all cables connected to your drive are secure. If it’s a laptop with a removable hard drive, make sure it’s seated properly.

3. Run a Diagnostic Tool

  • Many PCs offer built-in diagnostics you can access from the BIOS menu.

  • Run a hard drive test to check for hardware failure.

4. Use a Bootable USB or Recovery Media

  • If the system files are corrupted, boot from a recovery drive or installation media.

  • Use the repair options to fix startup issues:

    • On Windows: Choose “Startup Repair”.

    • On macOS: Boot into Recovery Mode and use Disk Utility.

5. Replace the Drive (If Necessary)

  • If the drive has failed (you’ll often hear clicking noises or get error codes), it may need replacing.

  • Restore your OS from a backup or reinstall it using recovery media.

At PC Expert Services, we are committed to providing accurate and reliable repair estimates. To ensure this, we offer a free diagnostic service to thoroughly assess your device and identify the exact issue.

A crashing custom gaming PC can stem from various issues, including overheating, faulty hardware, outdated drivers, or RAM problems. To troubleshoot, check temperatures, ensure components are properly seated, update drivers, and test RAM stability.

Here’s a more detailed breakdown of potential causes and troubleshooting steps:

1. Overheating:

Check Temperatures:
Monitor your CPU and GPU temperatures during gaming using monitoring software. If they reach high levels, it could be a sign of overheating.

Ensure Proper Cooling:
Make sure your CPU cooler is properly installed and that your case has adequate airflow.

Clean Dust:
Dust buildup can hinder cooling, so clean your PC’s fans, heatsinks, and case.

2. Hardware Issues:

RAM Problems:
Faulty or mismatched RAM can cause crashes. Test your RAM stability.

Power Supply Issues:
A faulty or insufficient power supply can lead to crashes, especially under heavy load.

Motherboard Issues: A faulty motherboard can cause random crashes or shutdowns.

Graphics Card Issues:
A faulty or overheating graphics card can lead to crashes during gaming.

3. Software Issues:

Outdated or Corrupted Drivers:
Ensure your drivers, especially for your graphics card, are up-to-date.

Driver Conflicts:
Conflicting drivers can cause instability.

Corrupted Operating System:
A corrupted Windows installation can lead to crashes.

Background Applications:
Some software can interfere with gaming performance, so close unnecessary programs.

4. Troubleshooting Steps:

Check Event Viewer:
Look for error messages in the Event Viewer (Windows + R, type perfmon, press Enter, expand Monitoring Tools, select Reliability Monitor) to identify potential causes of crashes.

Check for Error Codes:
If your PC beeps or displays error codes during startup, note them down and research their meaning.

Reseat Components:
Ensure all your components, including RAM, graphics card, and power supply connectors, are properly seated.

Try a Different Power Supply:
If you suspect the power supply, try a different one if you have access to one.

Clean Install Windows:
If you suspect a corrupted Windows installation, try a clean install.

Stress Test Components:
Use stress testing software to identify potential hardware issues.

5. Specific Issues:

Blue Screen of Death (BSOD):
If you’re getting BSODs, search for the error code online to find specific solutions.

Game-Specific Crashes:
If the crashes only occur in specific games, it could be a game-related issue.

Upgrading Laptops

Upgrading a laptop can help improve its performance, expand its storage capacity, or enhance its capabilities. While the upgrade options available depend on the specific laptop model, here are some common upgrades you can consider:

1. RAM (Memory) Upgrade:

  • Increasing the amount of RAM in your laptop can significantly improve its multitasking capabilities and overall performance.
  • Identify the type and maximum capacity of RAM supported by your laptop.
  • Purchase compatible RAM modules and follow the manufacturer’s instructions to install them properly.

2. Storage Upgrade:

  • Upgrading the storage drive can provide more space for your files and potentially boost your laptop’s speed.
  • Consider replacing the existing hard disk drive (HDD) with a solid-state drive (SSD) for faster data access and better reliability.
  • Clone or reinstall your operating system and transfer your files to the new drive using appropriate software or professional assistance.

3. Graphics Card Upgrade:

  • Note that graphics card upgrades are often limited to gaming laptops or high-end models that allow for discrete graphics card installation.
  • Research compatible graphics cards and ensure your laptop’s power supply and cooling system can handle the upgraded card.
  • Follow the manufacturer’s instructions to install the new graphics card correctly.

4. Wi-Fi Card Upgrade:

  • If you’re experiencing slow or unreliable Wi-Fi connectivity, upgrading the Wi-Fi card can help.
  • Research compatible Wi-Fi cards that support faster connection standards (e.g., 802.11ac or 802.11ax).
  • Consult your laptop’s user manual or the manufacturer’s website for instructions on replacing the Wi-Fi card.

5. Battery Replacement:

  • Over time, laptop batteries lose their capacity to hold a charge effectively. If your laptop’s battery life has significantly diminished, consider replacing it.
  • Purchase a compatible replacement battery from the laptop manufacturer or a reputable third-party seller.
  • Follow the manufacturer’s instructions to safely remove the old battery and install the new one.

6. External Peripherals:

  • Consider expanding your laptop’s capabilities by connecting external peripherals such as a larger monitor, keyboard, mouse, or docking station.
  • Check the available ports on your laptop and ensure compatibility with the peripherals you intend to use.
  • Connect the peripherals following the manufacturer’s instructions or seek assistance if needed.

Before attempting any laptop upgrade, it’s essential to research and ensure compatibility between the upgrade components and your laptop model. Consult the laptop’s user manual, visit the manufacturer’s website, or seek professional advice if you’re unsure about any aspect of the upgrade process. Additionally, consider backing up your important data before making any hardware changes to avoid potential data loss.

  • Viruses or malware can cause various issues on your laptop, including sluggishness, pop-up ads, or system crashes.
  • Use a reputable antivirus program to perform a full system scan and remove any detected threats.

5. Check for Disk Errors:

  • Disk errors can cause performance issues or prevent proper functioning of your laptop.

  • They can provide specific troubleshooting steps or advise on further actions to take.

Remember, these are general steps, and the specific troubleshooting process may vary depending on your laptop model, operating system, and the issue you’re facing.
