Troubleshooting Steps To Fix The Issue

The ‘Operating System Not Found’ error message on your computer can be quite alarming. It indicates that your computer is unable to locate the operating system files required to boot properly. However, there are several troubleshooting steps you can take to resolve this issue.

First, check your computer’s power and data connections. Loose cables can sometimes prevent the operating system from being recognized. Make sure all cables are securely plugged in and that there are no visible signs of damage.
