Encountering an issue during boot-up is a common concern for HP or Acer users, as they may come across an error message indicating that no boot disk has been detected or that the disk boot failed.

This situation arises when the system is unable to locate the essential boot information required to initiate the operating system. In such instances, we will offer a comprehensive analysis of the specific cause behind this issue, presenting viable solutions to facilitate the successful booting of your computer system.

Why no boot disk has been detected?

When a computer encounters the "no boot disc has been detected" issue, it signifies a failure in the essential process of retrieving boot information from the hard drive, crucial for system startup. This problem may arise due to various reasons, including:

  • Flawed or loose connection of the hard disk.
  • Incorrect boot order configuration.
  • Corruption in boot configuration data.
  • Hard drive failure.
  • HDD/SSD lacking an operating system.

Identifying these root causes sets the stage for implementing effective solutions to address the "No Boot Disk Detected" or disk failure dilemma. Discovering the intricacies of each issue equips users with the knowledge needed to troubleshoot and resolve the problem successfully.

How to fix no boot disk has been detected error?

Addressing the "no boot disk has been detected" error requires a strategic approach. Here are 6 solutions to rectify this issue.

Solution 1. Verify Hard Disk Connection

To tackle the boot error, meticulously inspect the hard drive connection to ensure it's securely attached to your computer. External factors like laptop movement may loosen wires, leading to undetected boot disk errors. Exercise caution during this process to prevent hardware damage.

Step 1. Turn off the computer, remove the battery, and extract the HDD.

Step 2. Thoroughly clean all ports and cables before reconnecting the HDD.

⚠️Note: If you lack professional tools and expertise, consider seeking assistance from a qualified computer professional or engineer.

Solution 2. Modify Boot Order

In instances where the boot disk isn't positioned at the top of the boot order, the computer might attempt to boot from an alternative source, leading to undetected disk errors. To resolve this issue, consider adjusting the computer's boot order through the BIOS using the following steps:

Step 1. Power on your computer and access the BIOS by pressing F1/F2/F12/Del or the specified key.

Step 2. Navigate to the Boot option within the list of available choices.

Step 3. Locate the computer's boot order and utilize the arrow keys to elevate its position.

Ensure the boot disk takes precedence, facilitating the system's ability to locate valid boot information and mitigating the risk of undetected disk errors.

Solution 3. Restore the Boot Sector

Positioned at the initiation point of the bootable hard disk, the master boot record (MBR) plays a pivotal role in ensuring successful computer boot-ups. A corrupted MBR can impede the system's ability to recognize vital boot information, resulting in boot failures. Rectify this by repairing the boot sector, employing the user-friendly method.

Download and install MyRecover on a normal working Windows PC. Attach a USB flash drive or insert a blank CD/DVD to your computer.

Step 2. Select a way to create the WinPE bootable disk according to your needs and click "Execute".


There are three ways available to create bootable disk based on Windows PE.

  • USB Boot Device: To create a bootable USB Device.
  • Export ISO File: Use this method to make a bootable ISO file. After the ISO is exported, you need to burn it with a third-party burning program. Or, you can use the ISO to boot some virtual machines or burn it to other devices.
  • Burn to CD/DVD: To create a bootable CD/DVD. Here we take USB Boot Device for example.

Tips: "Add Drivers" allows you to manually add additional and necessary drivers into the bootable disk so that more devices will be available after you boot into WinPE.

Step 3. After you select the way and proceed, there will be a pop-up information window. The USB flash drive needs to be formatted and all data on it will be lost. If there is important data on it, please first make a backup. If you confirm, please click "Yes" to continue.
