Asus B85M-G Won't Boot From USB

[Acapella]

Hello! I just built a system with an Asus B85M-G motherboard, and I have Windows 7 Professional boot installation files on a USB Drive. It is a FAT32 format 3.0 with the installation files dd'd onto the drive from the .img file I got from my online download. I have been working at trying to solve this all day, browsed around here a lot and did lots of googling, sadly, to no avail. The system just refuses to use the USB Drive as a boot drive. I set it as the #1 priority, and disabled all other drives, and it just skips straight to BIOS on system start. Thanks in advance for any help that anyone is able to provide.

Use Rufus to create the bootable USB. Choose "MBR partition scheme for BIOS or UEFI CSM"
