My work laptop wont boot after a firmware update.

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
No bootable device -- insert boot disk and press any key
The update was going fine until the power flickered. I waited a long time before touching aynthing, then finally turned it off. Now it powers on but shows nothing. I've read about BIOS recovery features but I don't know whether my machine has them. Help me figure out my options before I start pricing new motherboards. pls help 馃檹
