1.Power off the computer.
2.Open the back panel (for laptops) or case (for desktops).
3.Ensure the HDD/SSD is firmly seated.
4.Restart the system.

Method 2 – Change Boot Order in BIOS:

Often, the system tries to boot from the wrong device. To fix no boot device found error, you must check your BIOS boot priority.

1.Enter BIOS.
2.Look for Load Default Settings or Restore Factory Settings.
3.Save and restart.

This method is especially helpful for those who upgraded from Legacy BIOS to UEFI and are facing the no bootable devices problem.

Method 4 – Run Windows Startup Repair:

If the issue lies in corrupted system files, use Windows recovery tools:

1.Insert a bootable USB with Windows 10/11.
2.Boot from it.
3.Select Repair Your Computer → Troubleshoot → Advanced Options→ Startup Repair.
4.This tool can fix missing boot configuration files without reinstalling the OS.

Method 5 – Fix Boot Device Error Without Reinstalling OS (Using Command Prompt)

If Startup Repair fails, you can fix the boot loader manually.

Steps:

1.Boot into Windows Recovery Environment. Do it by holding the Shift key while selecting Restart from the Start menu’s power options.
2.Select Repair Your Computer → Troubleshoot → Advanced Options
3.Select Command Prompt.

4.Run the following commands:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands repair the MBR (Master Boot Record) and rebuild boot configuration data, often resolving the no boot device with command prompt error.

Method 6 – Run Disk Check:

Sometimes the disk is not recognized during boot due to bad sectors.

From Command Prompt, run:

chkdsk C: /f /r

This scans and fixes disk-related issues that may cause troubleshooting boot device error messages.

Method 7 – Reinstall Windows (Last Resort)

If nothing works, you may need to reinstall Windows. Ensure you back up data (if possible) using an external drive or live USB before proceeding.
