Flash the bios

Immediately apologize for my English :)
After installing Fedora on a laptop, broken boot and efi menu. I tried to use efibootmgr, but received empty response. After that I tried to lod DOS disc images, and iso on grub2, but this method did not work.
Please help me, I'm confused. :(
My laptop Fujitsu LifeBook A552
OS - Fedora 18 Beta X64.

Dos tried to connect as follows:
menuentry 'biosupdate'{
linux /memdisk root=UUID=id partition
initrd /bioupdate.img
}
system reboot...

Attempts to use the command
menuentry 'biosupdate' {
linux16 /memdisk root=UUID=id partition
initrd16 /bioupdate.img
}
Error: Could not find the command linux16
Error: Could not find a team initrd16
how to do it?
