I have a Lenovo G580 on which I installed Windows 8 and several Linux distros which have messed with my booting. The last I used was boot-repair tool. I have an EFI partition on sda2. The Grub load and I can boot to windows or Linux Mint or Mageia.
It seems now I cannot access UEFI by my regular F2 key. On searching around I found this thread: BIOS Setup Menu is not Accessible I want to know how can I get back my UEFI settings menu? From what I understand, I have messed up my Lenonvo's NVRAM. The tool efibootmgr shows no entries at all.Is there a safe way to restore it? I can boot to Linux but any change I make may render my laptop bricked as there are no other boot option.
