I have non genuine windows on my laptop and my laptop is also very old ( lenovo G580 ) . The problem i am facing is that i am unable to access bios settings which i need to enable virtualisation . ( yes my device supports virtualisation ) . I have tried it many ways , by constantly pressing f2 , f1 , Fn + f1 , fn + f2 and other ways . I have also disabled fast startup from battery settings . I have also tried to access it through settings < recovery < restart now < advanced options ...but the UEFI firware option is missing there. Please help.
