Description and Symptoms

The error messages, alerts, warnings, and symptoms below are tied to this error.

Symptom 1: “Disk Boot Failure” error screen on startup

Every time a computer is turned on, as part of the boot process the BIOS tries to find a bootable drive to continue the loading process by starting its first sector. However, if BIOS is unable to find a drive to boot from, then a “Disk Boot Failure” error screen is displayed and the boot process is halted.

Here is an example of “Disk Boot Failure” error screen for all versions of Windows:

Causes of this Error

This error has been known to occur as a result of one of the following causes:

Cause 1: Incorrect BIOS boot order

The most common cause of this error is an incorrect order of boot devices in BIOS. Usually BIOS tries to find a bootable drive according to its boot device order, so if a PC has a floppy drive set to a higher priority than a hard drive, and there is a floppy disk inserted – then the PC tries to boot from a floppy disk, and a error message is displayed.

Cause 2: Faulty data cables

Like all components of our PC’s, hard drive data cables tend to deteriorate as the time passes. If the same data cable was used for several years(or even the same one across several computers), then it might me the cause of periodic read/write errors that can affect the loading process.

Cause 3: HDD is damaged

A hard drive can become damaged or inaccessible due to read/write errors, power outages, or virus attacks. If that’s the case, then the drive should be checked for errors and scanned for viruses to make sure that it works correctly.
