BIOS SETUP MENU IS NOT ACCESSIBLE
I purchased Lenovo G580 on 11/07/2012. I installed Fedora 17 in it. Yesterday I installed Windows 7. After successful installation, a strange problem appears. The system automatically set the atheros ethernet as 1st boot device. In the bios screen when i pressed F2, nothing happened, it can't be able to go to bios setup. When i pressed F12, boot device menu opened, where 1st boot device is Fedora.

my bios version is phoenix SC-T v2.2

can anyone provide me the bios file? i can't find it anywhere..

RE: BIOS SETUP MENU IS NOT ACCESSIBLE
Hey thanks for your reply. I think I figured it out.

The problem is with UEFI based bios. Lenovo G580 comes with UEFI ON by default. First thing we need to do is disable this option from bios and then install Ubuntu on top of it. Now I'm using Ubuntu and Windows 7 dual booted on my G580. Feel free to contact me in case of any issues here.

Hey I'm having a similar issue, my UEFI bios is messed up so now I can't get into my BIOS menu to turn it off!!!

I'm not sure how to fix it, my F2 for Bios and F12 for boot menu are both broken now

PS: Lenovo U410 Laptop...

Any way to clear UEFI NVRAM?!?!?

RE: BIOS SETUP MENU IS NOT ACCESSIBLE
For the sake of future generations, I post my experience regarding this issue here:

This nonsense happens only after installing something other than Windows 8/8.1 in UEFI mode. Usually it's linux, but if it's not, god bless you, skip to solution #2.

SOLUTION #1:
Your only way to interact with UEFI is via your Linux system, so don't [censored] it up.
Ubuntu/Linux Mint/Archlinux etc. for some reason don't install properly on Lenovo G580 in UEFI mode. I have no idea why, but they always register themselves in UEFI boot sequence as entry number one. And that's the exact reason why BIOS isn't accessible anymore, Setup Utility is always "Boot0000" (entry #1), therefore Linux overwrites it and UEFI doesn't know about Setup anymore.
Luckily, these great people, Lenovo engineers, integrated some sort of emergency default settings. When UEFI lacks an entry, it restores itself from these defaults. Problem is, after installing Linux Boot0000 is still there, even if it points to something different from Setup, it's still there and the solution is to remove it.
Code:
[sudo] efibootmgr -b 0 -B
That's it. There's no Boot0000, system will restore the default entry: "Enter Setup Utility". Your OS would become inaccessible, but who cares, there are plenty of guides how to restore it.

SOLUTION #2:
I personally experienced this kind of problem twice. And the first time I screwed up trying to find a solution like the one above. I practically bricked my laptop. If you were as stupid as I was, bring your laptop to Lenovo, they'll replace mobo for free.
