How to Fix The Error “Disk Boot Failure Insert System Disk And Press Enter”

When you boot your PC, a modern machine, or an old and dated one, one error that you can encounter is the Disk Boot Failure, Insert System Disk, And Press Enter.

The message appears on a black screen and stops you from starting your computer normally. At first glance, the word ‘disk’ in the error message gets most people thinking that the error is related to the hard disk. However, that is usually not the case. The ‘disk boot failure’ message means that the system failed to boot from the disk.

Booting (or starting up) is the process where software and hardware come together and all the components of the PC are made available to you. BIOS (Basic Input/Output System) is the first thing that gets activated in this process. BIOS contacts Master Boot Record (MBR), which is the first sector of a partitioned hard drive that contains information about the Operating System (OS).

If in this booting process, BIOS is not able to successfully retrieve information about the OS from the MBR of the drive, the Disk Boot Failure message shows up. The second part of the message, therefore, requests the user to insert a drive from where the BIOS can get information about the OS and start the device.

It is also possible that there is a CD in your device, which is hampering the boot process. You can remove the CD or any external device connected to your computer or laptop to fix the error.

Even if that doesn’t fix your issue, there are several ways to quickly and easily solve the problem.
