How to Recover Data After Boot Disk Failure & Fix the Error

Browsing Windows Forum as well as other major forums and portals, you will find that the error message “disk boot failure insert system disk and press Enter” is troubling lots of users. Here is a true example from Reddit:

Getting a "Disk boot failure insert system disk and press Enter" error message on startup after the computer crashes. Earlier I plugged in a new flash drive and began to put files on it when my computer froze. When I rebooted, I received that error message and can't get any further. I've tried disconnecting the flash drive and restarting and it didn't help.

I tried searching but I had no idea if anybody else's problems were related to mine. I'm not the most computer-savvy guy and I would appreciate any help.

Useful Disk Boot Failure Solutions

Why Does Disk Boot Failure Happen

Knowing why the disk boot failure occurred can help you address the issue more specifically. Here we list the most common causes.

Incorrect BIOS boot order: BIOS, a program that runs at the beginning of a computer startup, tries to find a bootable drive according to its boot device order. Setting the wrong order for the booting devices might leave the computer failing to boot.

Boot sector viruses: Some viruses can cause damage to the boot sector of the hard disk. If the boot sector is infected, the hard disk drive fails to boot.

Damaged disk: Damaged hard disk or partition is also a possible reason that causes your system fails to boot.

Damaged operating system: When your operating system is corrupted, BIOS will not be able to load it properly. Then the boot disk failure occurs.

Newly installed hardware: When you put a new disk in your computer and the disk configuration is wrong, you may also not be able to successfully boot the computer.

Now let’s see the corresponding disk boot failure solutions.

Solution 1: Change BIOS Boot Order

When the boot order is set incorrectly, you can follow the steps below to change the boot order safely on Windows 10:

1. Restart your computer.
2. Open the BIOS.
3. Go to the Boot tab.
4. Change the order to position the boot hard disk as the 1st option.
5. Follow the instructions on your screen to save these settings.
