Bios for my hp dv6775us

Hey guys i just joined the forums and was having a problem with a friends hp laptop. here are all the specs i can gather

Model: hp dv6775us
system board id: 30d2
processory type: intel core 2 duo
memory-3gb
bios version: f.33



So heres the problem the computer boots up to the hp splash screen and stays their . if i press any key it will go in to the setup utility but will only have a main tab which displays specs on the computer. if I leave it at the spalsh screen it will eventually go to the bios setup utility. I figured i needed to flash my bios so i go to hp's website only to find that they only have the bios in a winflash version (where you need to be in the windows os to flash the bios) what can i do ?

thanks
