I bought a used computer upgraded to windows 10 that would not activate. Want to restore to factory setting where windows 7 is installed on computer from Gateway. System will not let me into advanced boot options and there is no gateway recovery option in Windows. I have tried Alt+F11, Alt+F10, F8 and nothing works. Can anyone help me? I also know that the system is partitioned. There is a 'System Reserved" part of the partition, which from everything I read is where I can go back to factory settings. The gateway is ZX4800. Thanks
Cynthia
