Summary: This blog discusses the causes of a disk boot failure and then provides possible resolutions. If you happen to lose any of your files due to disk boot failure or while fixing the disk, you can opt for a data recovery software like Stellar Data Recovery Professional.

What is Disk Boot Failure?

Disk boot failure occurs when your Windows doesn’t load properly, at the time of PC startup. It is a frustrating issue as it prevents you from accessing your computer.

The error message looks like below:

It happens when your PC’s BIOS (Basic Input/Output System) cannot locate the boot device. The boot device contains the files by which a system boots into the Operating system. A failure in the process can happen due to the following reasons:

a. BIOS has an incorrect boot order: This occurs when the boot sequence is incorrect, i.e., the files meant for a PC startup are in an incorrect order.

b. Malfunction in the Operating system: This occurs when BIOS fails to recognize the operating system.

c. System disk corruption: This happens when your system hard drive gets damaged or unreadable.

Let us look at the different methods by which we can fix the Disk Boot failure issue.

Method 1: Change the BIOS’s boot order

1. Restart your PC

2. Upon restart, you will see a BIOS key (set by the manufacturer), displayed on the monitor. The most common ones are F10, F2, Esc, F12, F1, Del. Click the appropriate key.

3. The boot tab will then open.

4. Place your hard drive/hard disk as the first in order 

5. Save the changes.

6. Restart your PC.

Method 2: Repair Operating System

If Method 1 doesn’t work, then the next course of action should be to repair the corrupt OS. To use this method, you need to first burn Windows 10 in a CD/DVD or a USB drive.

1. Put the USB drive or CD/DVD in your computer and boot the computer.

2. In the Windows Setup page, click Next.

3. On the next screen, select Repair your computer. Then click Troubleshoot.

4. A page with Advanced options will open up.

5. From the options, select Startup Repair.

Method 3: Fix Unrecognized System Disk

Your disk might be damaged or have bad sectors, and this can cause a boot failure. The remedy of this is a little tricky. You’ll have to take out the hard disk from the system first and connect it to a working computer. You can then use the steps as described in the blog post How To Repair Bad Sectors In The Hard Drive.

A disk boot failure can be a frustrating issue for anyone. It is caused by an error in the boot order, which can be easily fixed.
