Comment 181 for bug 1040557

@val. I have ubuntu under uefi. With a bios update grub gets erased and as you say 'Secure boot' is enabled. All I needed to do is disable 'secure boot' and run SystemRescueCd on a usb stick which detects the ubuntu present on the hard disk, I just boot into it and run an 'grub-install /dev/sda' and all is fine runing in uefi boot (see post #128 for more info about my setup).
