‘No boot device’ Hard Disk Error and Recovery

‘No boot device’ Hard Disk Error and Recovery

When the computer system starts, it looks for a boot device generally to load an installed operating system. Hard disk is the common boot device used, while in some cases Floppy Disk, USB Flash drive, DVD, CD-ROM etc. are also used. If the system cannot find any boot device (when hard disk is being used as boot device) or detects it but displays an error message related to corruption, you might encounter issues pertaining to data loss. If data backup is unavailable or faulty, such issues lead to Hard Disk Recovery.

Consider a scenario, when you start the system and get the following error message:

"No boot device"

With some of the systems, you may also get options to reboot the system or enter setup. The boot process gets halted as the system doesnt find any operating system to load.


The above error message may be encountered because of the following reasons:

• A removable drive is inserted/attached to the system, which doesnt contain boot files
• Hard disk is not properly connected to the system
• Hard disk is not correctly configured in BIOS (Basic Input Output System)
• Boot partition is not the active partition
• Hard disk is physically damaged


Based on possible causes, you need to try these steps to recover the lost data:

• Verify if no removable disk is inserted or attached to the system. If it is, you should remove it (viz.a floppy disk).
• Check that all hard disk cables are physically fine and properly attached.
• If you have recently altered the BIOS configuration, check that hard disk is configured properly.
If you still face the same issue, power down the system and replace the hard drive. Use your recent data backup to restore lost data. However, if backup is unavailable or damaged, you should consult and send the failed hard drive to data recovery service professionals for diagnosis and recovery.
