1. Check the Hard Disk Connection
Check the hard drive connection to your computer, ensuring it's properly connected, as laptop shaking can cause wires to loosen and lead to boot disk errors. Be cautious when handling it to avoid damaging the hardware.
Step 1. Remove the battery and hard drive from the computer to turn it off.
Step 2. Clean all ports and cables and reconnect the HDD.
Note: If you don't have the necessary tools and expertise, it's best to consult a computer professional or engineer for assistance.
Boot Device Not Found Hp Laptop? How to Fix?
If you're seeing an error on your HP laptop, such as 'Boot device not found HP laptop,' then continue reading this article as we show you how to fix this. To resolve the issue, you can try booting your laptop in safe mode, checking the boot order in the BIOS settings, or running a system file checker to identify and fix any corrupted system files.
2. Change the Boot Order
If the boot disk is not at the top of the boot order, the computer will try to boot from another source, potentially causing undetected disk errors if it can't find valid boot information. To resolve this, change the computer's boot order in the BIOS by following these steps:
Step 1. To access the BIOS settings on your computer, turn it on and immediately hold down the key that triggers the BIOS setup. This key is usually F1, F2, F12, or Del, but it can vary depending on the computer model.
Step 2. Select the Boot option from the list of options.
Step 3. To change the boot order, you can enter the BIOS settings by pressing the corresponding key (usually F2, F12, or Del) when the computer first starts up. Once in the BIOS settings, navigate to the "Boot Order" or "Boot Priority" section, and use the up and down arrow keys to reorder the devices.

3. Repair the Boot Sector
The master boot record (MBR) is a crucial component located at the beginning of the bootable hard disk, responsible for facilitating a successful computer boot-up. However, if the MBR becomes corrupted, it can prevent the system from recognizing boot information, ultimately leading to a failed boot. Fortunately, there are two ways to repair the boot sector:
Use Qiling Disk Master to Rebuild MBR
Qiling Disk Master is a user-friendly tool that simplifies the process of repairing the Master Boot Record (MBR) and creating a WinPE bootable disk, making it ideal for those who are not familiar with computer operations.
Free download this powerful tool and rebuild MBR:
Step 1. Create a WinPE bootable disk
- Launch Qiling Disk Master, click "Bootable Media" on the toolbar, and select "Create bootable media".
- Click "Next" to finish the process.
Step 2. Boot Qiling Disk Master Bootable USB
- Connect the bootable USB or CD/DVD to your PC.
- When you restart your computer, press F2 or Del to enter the BIOS screen. From there, set your computer to boot from a removable device or CD-ROM drive. This will allow Qiling Disk Master to run automatically once your computer boots up.
Step 3. Rebuild MBR
- In the "Disk management" tab, right-click the disk's head and select "Rebuild MBR".
- After selecting the type of MBR, click "Proceed" and the MBR will be successfully rebuilt on the specified disk.
If you encounter other boot errors, you can use Qiling Disk Master to resolve them:
Use CMD to Rebuild MBR
If you are familiar with computer commands, you should use the Windows Media Creation Tool to create bootable media and then use the command prompt to repair the MBR in the Windows recovery environment:
Step 1. To start the process, insert the Windows bootable installation CD or DVD into your computer's CD or DVD drive. Then, restart your computer.
Step To start the command prompt, select the "Troubleshoot" option from the "Choose an option" menu, and then select "Command prompt" from the "Advanced options" menu.
Step 3. Enter the following commands in sequence at the command prompt box and press enter:
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /scanos
- bootrec /rebuildbcd
Be cautious when executing the commands to prevent data loss. After running the commands, restart your computer to verify if the issue with the failed disk has been resolved.
4. Check the File System
If your system hard drive has a file system error, you may get a "the disk has failed" error. To fix this, you can use bootable media to check and repair the file system. This process is similar to method 3 and involves creating bootable media. You can then use this media to check and repair the file system on your hard drive. This is a way to detect and fix the file system error on your hard disk.
Use Qiling Disk Master to Check File System
Qiling Disk Master provides "Check File System" and "Disk Surface Test" to help you find and fix hard disk errors, offering a simpler and more comprehensive alternative to Windows commands. After creating a bootable USB, you can use the tool directly to troubleshoot issues.
Step 1. Right-click the target partition that has a problem.
Step 2. Choose "Advanced" > "Check File System".
Step 3. Confirm if you want to hide the partition or not.
Step 4. In the Check File System window, select the "Fix the error on the disk" option.
Step 5. Click "Proceed" to check errors on your partition.
The tool can check hard drive health comprehensively and alert you if there are problems with hard drive performance or temperature.
Run CHKDSK to Check File System
CHKDSK is a method Windows provides to detect and repair file system errors. To use it, go to the command prompt and type "chkdsk" followed by the drive letter of the drive you want to check, for example, "chkdsk C:" or "chkdsk D:". This will scan the drive for errors and prompt you to schedule a full disk check for the next reboot, giving you the option to automatically fix any errors it finds.
Step 1. Start your computer from a Windows bootable device.
Step 2. Go to Advanced Options and select Command Prompt.
Step 3. Type the command: chkdsk c: /f/R/X and press Enter.

5. Run the Automatic Repair
To fix the error that prevents your PC from booting, you can run the Automatic Repair or Startup Repair on your system. However, before doing so, you must use Qiling Disk Master or Windows installation media to enter the Windows recovery environment.
Step 1. Boot from the CD/DVD and press any key to continue.
Step 2. Click on Repair your computer and select Troubleshoot.
Step 3. Select Advanced options>Automatic/Start-up Repair.
Step 4. Wait for Windows to finish repairing automatically.
6. Do A Fresh Install of Windows
If all solutions are not working, a Windows system may fail. To fix the error, you can do a fresh install of Windows, but this will erase all files, so it's recommended to back up important information before doing so. Alternatively, you can copy a partition to another drive to save your files. This will allow you to start fresh with a clean Windows install while preserving your data.
