I've tried what feels like every tutorial on creating a bootable USB. Went with dd'ing zeroes to the drive, then fdisk, mkfs.vfat, alternatively gparted, then either dd'ing the iso to the /dev/sd or mounting both and just copying. All those left me with either "not bootable" or "missing OS" when I tried. Gave up yesterday and the first try using woeusb today just worked. Might be that the problems I had came from upgrading win 8.1 to 10 when it came out. So far even the wifi stick works out of the box without disconnecting. Next is to figure out how to make dual boot happen with my existing debian SSD.
