|I don't see what you can when you are in the BIOS screens. I just put it out there for you to review again.|
You seem to be convinced you should be able to boot from the USB drive. Perhaps you are right but you have the drive prepared wrong or have the wrong files.
Did you download 61M29306.zip?
You need to extract that zip file and then follow the instructions on how to prepare the floppy (flash).
If flashing from the boot you need two files on the media. AWARD flash and the Bin file.
There is also a Windows flash option included.
Your problem might be that the flash file wants to backup the existing BIOS file and it can't write to the USB flash drive. The workaround would be to use a floppy or flash from within Windows.
