Troubleshooting No Operating System Found Error

B.

Based on the given scenario, the error message "No Operating System Found" indicates that the computer is unable to find a bootable operating system on any of the connected storage devices. Since the error message disappears when the new secondary hard drive is unplugged, it is likely that the boot order is incorrectly configured or the new hard drive is causing a conflict.

The next step for the technician should be to check the boot order in the BIOS/UEFI settings of the computer. The boot order determines the order in which the computer looks for a bootable operating system on the connected storage devices. If the boot order is not set correctly, the computer may be trying to boot from the new secondary hard drive, which may not have an operating system installed on it.

To check the boot order, the technician should restart the computer and press the key to enter the BIOS/UEFI setup (usually F2, Delete, or F10). Once in the setup, the technician should navigate to the boot order menu and ensure that the primary hard drive with the operating system installed is set as the first boot device.

If the boot order is correctly configured and the error message still appears, the technician may need to perform further troubleshooting, such as checking the hard drive connections, performing a Windows Recovery, or running the chkdsk command to check for disk errors. However, formatting the new drive should not be necessary at this point, as it would delete any data stored on the drive and not necessarily solve the problem of the operating system not being found.
