I 'am trying to flash bios via usb with no O/S I would LIKE to know the step by step process if anyone can help out that would be great!Not every computer's bios can be updated through USB.  You'll have to check the Manufacturer's website for what update options are available for your system.

Why do you want to update the bios ?having an issue with windows 7 install it freezes after first INTIAL copying of files screen then just stays at that screen. I used hp format utillity to made my usb bootable, downloaded the bios update executable, now it says find DOS files to add i dont know which dos files i need .Before messing with the bios to fix this problem try a few other things first.

Check the installation media for SCRATCHES and or smudges and clean if possible.  Reseat all the power and data cables, reseat the system's ram.  Blow the dust out of the system.  Try the install on another hard drive.  If none of that works try swapping in another power supply of equal/greater wattage.  A failing power supply can have a variety of effects on computers.absolutely actually this is a laptop iam working on and someone had told me that it was a mobo issue something to do with the hard drive controller was not sure wanted another opinionOh it's a laptop... Ok

That does MAKE it more difficult to isolate the problem. 

let's see..   Without bringing it to a tech SOMEWHERE and paying money, you're going to have to put some work into this.  Test the voltage output of the charger first, with a volt meter.  Battery may not be working well and charger may be under par.  Always have to check for power problems.  No power, no dice, period.

Pull the ram and re-seat that.  Re-seat the hard drive.. You can access both of them most likely from the bottom of the laptop.  Sometimes there is one stick of ram under the keyboard.  Try with only one stick of ram, and each stick in a different slot.  You can run MemTest86 but changing the ram around is quicker. In other words if it work with only one ram module installed then you can bet the other module is bad. You can tell if the hard drive controller is bad by hooking the drive up to another computer with an adapter and testing it in that machine.  If it works then the drive is good, and the controller on the laptop is likely an issue.

Do these things and try the install again.  If you've gotten this far and still not working, you're going to have to take the laptop apart for further troubleshooting... If you want to go down that road let me know I'll try to help.

I believe he thinks it's a solution to his problem installing Windows.
