Laptop: HP Compaq 6710b

I can boot from usb just fine with the following usb flash drives:

  • Cruzer micro 4GB
  • HP 4GB

The flash drive that will not boot:

  • Flash Voyager 8GB

To knock out variables I did the following:

  • Using Hard Disk Low Level Format Tool I performed a low level format
  • Full erase with Flash Memory Tookit
  • In windows 7 I formated the drive to fat32
  • Used USB-Boot-Tester to write to the drive
  • Also used uNetbooting with various distros to see if that would make a difference

My guesses on what could be preventing the drive from booting:

  • The laptop does not support booting to usb flash drives larger than 4GB
  • The drive is defective in some way
