Hello, recently I wanted to reinstall my Windows and make a single partition on my HDD. So I enter in advanced settings → command prompt and I cleaned my partition but also she erased my bios… Now when I turn on my laptop it’s show me a window with “Boot menu” (boot menu is the single option). I tried to enter in bios from F2; Fn+F2; novo button, butt nothing, sometimes only a black screen. Also, I tried to change my CMOS baterry, nothing too… I searched on lenovo for bios, but there is only an update.exe
What can I do?
