I had to buy a USB Expansion PCI card because my motherboard wouldn't handle USB storage devices anymore. Now when I'm using my USB flash drive to boot up to something on startup, it doesn't recognize the flash drive in the expansion card, how do I make flash drives/externals pickup on boot up? Any help is greatly appreciated!
