You wake up, see that the sun is out, and decide that today will be a good day. You get ready, drink your coffee, and try not to watch the news or look at your phone in the morning if either makes you feel bad. Then, you head to your office to start your day. As soon as you're comfortable, you turn on your computer.

Only one thing is wrong. "boot device not found" is what you see when your screen turns on. Really? Your computer isn't working on a day that started great, and it says, "boot device not found." What does that mean? Even though this error sounds scary, most of the time, it can be fixed.

Errors like "boot device not found" happen a lot in computers. It happens for several reasons, but the result is always the same. Even if you can't fix this problem, you can still get your data back with the help of a company like DriveSavers. But I'll talk about that later.

Here's what you need to know about no bootable device found errors, why they happen, and what you can do to fix them.


You've probably been blissfully unaware of the critical role played by the boot device… until it failed. When your computer tells you the boot device is not found, it can't find the hard drive containing the instructions for loading your operating system. Of course, you know the purpose is there because you haven't taken your computer apart and physically removed it. And you're pretty sure no one has played a cruel joke on you. So what gives?

Usually, when you press the power button, the BIOS recognizes the boot device and uses the software to start your computer's operating system. But without the instructions to create the operating system, your computer is stuck, and you're most likely staring at a black screen with a blinking command prompt.

A few things could cause your computer to say, "No bootable device found." Here are the four most common ones.


Failed hard drive

Most boot devices are a part of the computer's internal hard drive. If your hard drive breaks down or corrupts, your boot device will. The BIOS can't recognize startup software on a broken dream, so it will think there's no boot device to be found.


SATA/IDE cable malfunctioning

The cable that connects the hard drive to the motherboard can break or stop working. If this happens, the BIOS can't talk to the boot drive, so it will tell you it can't find any bootable devices.

Boot sector or partition table corruption

When a disc's metadata drive is broken, the BIOS might see an empty partition on the drive where the operating system is stored. If so, the BIOS thinks the boot drive is missing and gives an error message: No bootable device found.

Configuration errors : 

Have you changed your operating system or computer's software architecture? The BIOS may get confused. The BIOS may try to boot from the incorrect disk, find no software to start the computer and display the no bootable device detected message.

How do you fix the "Boot Device Not Found" error in the Laptop?

Method 1. Change boot order

First, check that the disk you are booting from on the hard drive is correct. If you make the mistake of setting it to boot from a device that is not bootable, it will not be able to start successfully from the unbootable device and will instead display the error message "Boot Device Not Found."

Installing an operating system on your hard drive would be much appreciated. You need to go into the BIOS and modify the boot order, then let it boot from the bootable media. If it is the boot device and you have received this error, the following solutions are available.

Method 2. Perform a hard reset

You can carry out a hard reset if you run into the issue where no boot device is found. A hard reset, sometimes called a forced reset, deletes all the information stored in the computer's memory and may restore regular operation. You are compelling the operating system to delete and reconfigure the software connections between the BIOS and the hardware by doing a hard reset on your computer. The following procedures need to be carried out to carry out a hard reset:

Step 1: Put the computer into sleep mode. Remove the computer from any port replicator or docking station it may connect to.

Step 2: Remove the AC adapter from your computer and disconnect any external devices.

Step 3: Take the battery out of the cabinet where the batteries are stored.

Step 4: Maintaining pressure on the Power button for around 15 seconds will allow you to release any electrical charge that may have been stored in the capacitors that guard the memory.

Step 5: Do not connect any of the computer's peripheral devices, including USB storage devices, external screens, printers, etc. Instead, plug in the AC adapter and the battery and plug the adapter into the computer.

Step 6: Put the PC in the on position. If a start menu appears, use the arrow keys to pick Start Windows Normally, then press Enter to continue.

If restarting the hard disk does not resolve the issue, you may use the following technique.

Method 3. Restore BIOS default settings

It's possible that restoring the default settings in the BIOS would repair the problem that says "boot device not detected" in HP. The steps that you may take are as follows:

Step 1: power down the machine and wait for at least five seconds.

Step 2: After restarting the computer, continuously hit the F10 key to access the BIOS configuration menu.

Step 3: When you are on the setup page for the BIOS, hit the F9 key to choose and load the default settings for the BIOS setup.

Step 4: To save and exit, use the F10 key.

Step 5: When asked to exit while saving changes, choose Yes and press Enter.

Step 6: When prompted, restart the computer by following the on-screen instructions.

If the machine usually restarts, your work is finished. Proceed to the next step if the error message "boot device not detected" continues to appear after attempting the previous one.

Method 4. Check hard drive

If the procedure described above cannot resolve the issue, you might think about doing a check on your hard drive. If you need to examine a hard drive, we strongly suggest using the AOMEI Partition Assistant Standard. This utility may assist you in checking partitions, repairing faults, and checking the disk itself.

You need to connect your boot disk to another Windows PC on which AOMEI Partition Assistant has been installed. Another option is to use AOMEI Partition Assistant to generate a bootable USB drive that you may use to start your machine successfully.

Step 1: Enter the AOMEI Partition Assistant application and choose the hard disk that will be your boot device. Right-clicking the boot partition and selecting Check Partition from the context menu will bring you to this screen.

It will allow you to choose the method you want to use to examine partitions and correct faults.

Step 2: Right-click the hard disk to launch your computer and then choose Surface Test.

After you click the Start button, the examination will immediately begin.

Last but not least, if your hard disk has any issues, address them, then the problem with the HP computer where the boot device is missing could be resolved.

Method 5. Rebuild MBR

The Master Boot Record, or MBR, is an essential part of the hard disk regarding how the computer boots up. If it is damaged or contains problems, the error message "boot device not found" will be shown. You may repair MBR with the assistance of the AOMEI Partition Assistant.


Step 1. To repair the MBR, right-click the hard disk and then pick the "Rebuild MBR" option from the context menu.

Step 2: In the pop-up box, choose the kind of MBR corresponding to the currently installed operating system, then click OK to begin rebuilding the MBR.

After that, you'll have to restart your Laptop to continue.
