Tyler,  When a USB stick is formatted for UEFi booting, it will show up in the boot menu under the heading "UEFI BOOT".  I have formated regular USB sticks with "Rufus" that show up in the "UEFI BOOT" section of the boot menu, but the created DIA USB will not show under the "UEFI BOOT". My question to you is why does the DIA USB stick NOT show up in the "UEFI BOOT" section in the boot menu, when it is formatted with fat32?
I have a E6440 with UEFI enabled in the bios.  I have installed windows 7 64bit Ent.  I have installed DIA and created a usb stick and captured my image.  Now when i test the usb stick on the same E6440 with UEFI enabled, the usb stick DOES NOT show up in the boot menu under "UEFI BOOT" what did i do wrong?  why wont the usb stick that i create with DIA show up with UEFI enabled? 
Create DIA USB for UEFI boot?
