    It is a EFI bios generally easy to recover and this method is describe at dozens of places around, eg:http://forums.mydigitallife.net/thr...hod.-Use-andy-s-tool-to-obtain-possible-names., anyway:

    preparation:
    1- download the pavillion dv7 1247cl bios from HP: ftp://ftp.hp.com/pub/softpaq/sp45001-45500/sp45071.exe
    2- extract the content of sp45071.exe with Universal Extractor
    3- format an USB stick in FAT or FAT32
    4- copy 30FCF49.fd from extracted bios to USB stick, rename the file 30FC.fd

    recovery:

    1- power off the laptop, remove the power cord, remove the battery.
    2- insert USB stick
    3- press Windows b keys
    4- insert power cord
    5- power on, keep the 3 keys pressed few seconds, then release power and Windows b keys.
    6- recovery is starting for one or 2 minutes (the USB stick should blink showing activity)

    regards

    if it doesn't work try to rename the bios file from 30FC.fd to FC.bin

    this model suffers from loose chipset BGA soldering and sometimes cpu socket solder.

    i just fixed 2 of them by using kester 951 no clean flux and 330 degrees for 3 minutes... wait the board warps so apply heat while watching it in angle so it dont overwarp and push solder against chip = splat balling is now glob of solder.

    this is the result of cheap board makers going thin on PCB
