My hdd recently died in my pc so i had to replace it with a new one. I downloaded windows 10 installation media onto a usb so that i could put windows 10 on my new hard drive, but when i tried to access my BIOS in my pc (Lenovo legion y520t-25ikl) i was unable to enter it. Please does anyone know how i can access my BIOS or do i need to completely replace my motherboard?
