How to Fix Disk Boot Failure  

Quite often, we get questions about an error called “Disk Boot Failure” from our users. In addition, many users have detected a loss of files in their computers. In this article, we will look at the main causes of the error “Disk boot failure, insert system disk and press Enter”, and the solutions.

Disk Boot Failure at Windows startup: the main causes and and the solutions

When you turn on your computer, the BIOS runs first, and then the operating system starts booting. If the BIOS cannot find the disk to boot from, you will certainly see the error message “Disk Boot Failure” in the screen. In addition, the boot process will be canceled and, as a result, you will not be able to access your data. If you want to fix this problem, you need to find out why it happens. Let’s look at a few basic reasons and, accordingly, the methods to eliminate them.

1. A damaged hard drive or partition

If the hard disk or partition is damaged, you will see a “Disk Boot Failure” error, because the operating system will not be able to boot.

The solution: in this case, you’d better replace the drive and reinstall the Windows operating system immediately.

2. Incorrect configuration of a new hard disk

Perhaps you have just installed a new hard disk into your computer. But when you try to start Windows, you still see the “Disk Boot Failure” message. In this case, the new hard disk is likely to be configured incorrectly.

The solution: after installing a new HDD, you need to insert the installation disc and restart the computer.

3. The hard disk is not connected correctly

In addition to incorrect configuration, your hard drive will not be able to communicate properly with your computer if it is not connected properly, and it will also lead to the “Disk Boot Failure” error.

The solution: in this case, you can turn off the computer, and then check the connection between the hard drive and the motherboard. After making sure that everything is correct, you can try starting Windows again.

4. Software settings conflicts

In addition, sometimes after installing any third-party software and restarting the computer you can also get this error. In this case, there is a great chance that the software conflicts with your operating system.

The solution: in such situations, the only way is to use a system recovery disc or simply reinstall your operating system. However, you may experience data loss in the process.

5. Boot Sector Viruses

Usually most viruses can only damage files on the hard drive, but there are some viruses that can damage the boot sector of the drive. If the boot sector is infected, the hard disk will certainly not be able to boot.

The solution: this situation is rather complicated. Removing viruses from the hard drive will cause a lot of problems in the BIOS settings and Windows system. It is quite difficult. Therefore, you must take daily precautions. For example, it’s easy to install a reliable anti-virus program and update it regularly.

6. Incorrect BIOS boot sequence

The BIOS is a program that works to find a bootable hard disk based on its boot order of devices when the computer starts. Therefore, if the BIOS boot sequence is incorrect, it cannot find a boot disk.

The solution: in this case, you can change the boot order in the BIOS. When you restart your PC, open the BIOS and go to the “Boot” tab. Then change the boot sequence so that the internal hard drive is the first boot option. Save the settings and restart your computer.

7. A Windows Failure

In addition, the failure to boot disk can also be caused by Windows system failures, such as damage to system files.

The solution: as in the above case, you must reinstall the Windows operating system.

A Windows Failure: damaged system files

We listed the main causes of the error “Disk boot failure, insert system disk and press Enter”. As we wrote earlier, this error is very often accompanied by loss of files. In case of a similar situation, we recommend using the data recovery software. For example, Magic Partition Recovery. This utility for file recovery includes various advanced algorithms that allow the program to return deleted files and folders that other recovery products do not even recognize.
