UEFI boot and GRUB2-- cannot reach BIOS menu

view story

https://bbs.archlinux.org – I am using UEFI boot and grub. Ever since installation, I haven't been able to open my BIOS menu or my multiboot menu. I am using a Lenovo Z580. When I turn on the laptop, I see the lenovo splash screen and the "Press F2..." on the bottom, and when I press F2 the text changes to "Please wait", but then goes straight to the grub screen. I tried turning off the laptop, taking out the battery for 60 seconds and rebooting (I think that is the way to hard reset), but it didn't change anything. I read on this thread in the Lenovo forums that it might be a hardware probl (HowTos)
