On a Vostro 3700 you must copy the .hdr file and rename it to winery70.hdr.  Otherwise, the instructions above are spot-on!  Thanks!

Ok I figured it out. You need to make sure you format the flash drive to fat 32 first or the motherboard wont read the flash drive

@ferfuji: Here it worked for the first time. Check flash drive, try another USB port. Press and hold End key _while_ connect AC power and hold it for another few seconds... it loads and starts BIOS from USB, and a recovery screen comes in.
