The “No Boot Device Found” error on Windows 10 indicates that the computer is unable to locate the operating system files necessary to start up the system. This could be due to a variety of reasons such as corrupt files, a faulty hard drive, or a misconfigured boot order. Here are some steps you can take to resolve the issue:
- Check Boot Order: First, check the boot order in your system BIOS. Ensure that your hard drive is set as the primary boot device. To access the BIOS, restart your computer and look for a message that says “Press F2 (or another key) to enter setup.” Once you’re in the BIOS, navigate to the boot menu and check the boot order.
- Check connections: Make sure that all cables and connectors are properly connected to the hard drive and the motherboard.
- Use the Windows Recovery Environment: Boot your computer from the Windows installation media (USB/DVD), and select the “Repair your computer” option. This will launch the Windows Recovery Environment. Select “Troubleshoot” and then “Advanced options” to access the startup repair option.
- Repair your operating system: From the same advanced options menu, you can also try using the System File Checker (SFC) tool to repair corrupt system files. To do this, select “Command Prompt” and enter the command “sfc /scannow” to start the process.
- Check your hard drive: Run a diagnostic test on your hard drive using a tool like CHKDSK or a third-party disk utility. This will help you identify any errors or bad sectors on the hard drive.
- Reinstall the operating system: If all else fails, you may need to reinstall the operating system. This will erase all data on the hard drive, so make sure to back up important files before proceeding.
If you’re still unable to resolve the “No Boot Device Found” error, it may be a hardware issue and you may need to seek assistance from a professional technician.
