I have a Lenovo laptop, when I turn it on, it gives me a black screen with a message saying "BOOTMGR is missing press ctrl+alt+del to restart".
And I did it for many times but it did not solve the problem, I even tried to Google the problem and the expert advices but everything in vain. When power is ON, I press for the boot option keys like F2, F10, DEL and click on repair option.
My boot option is F2 and I have tried tabbing this key for several times and it did not open the boot menu. Even I've tried to open the system recovery menu (F8), but it did not work.
