    it says so somewhere in the manual that the usb stick must be fat 16/32, not ntfs, i read it while trying to find my error with updating bios.

    Just seems to be odd you can browse though your C drive but not flash off it thats all.

    The application (the flashing tool is dos) will not work without FAT32 - the wrapper that you navigate the USB stick with is able to read NTFS formatted drives.

    Hope that helps.
