firmware update nightmare.

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
i was updating teh work laptops BIOS using the P7H55-M PRO Bios package from ASUS. then the progress bar froze. since then, black screen. im reasoanbly technical but Ive never had to recover a BIOS. is this repairable at home?? the keyboard lights flash briefly when i press power, then notihng 😭 i have another computer available to download files and prepare a USB stick if a recovery procedure needs it. i just dont want to make things worse by guessing.
