Can you help me. I have a Inspiron M301Z laptop that originally had Windows 7, but I installed the free Windows 10 upgrade. I needed to have a ‘System Restore’ after it finished and rebooted, I got the error message ‘A operating system wasn’t found. Try disconnecting any drives that don’t contain an operating system. A full diagnostic test found no problems. I would prefer to reinstate the original Windows 7 and Dell drivers, but I assume installing Windows 10 removed the Windows 7 installed on my motherboard. How can I reinstall an operating system? Robert (kingsthorne50).
