Hi all. I'm trying to install Windows off of a USB. I have the .iso files already on the USB, but I still need to make it so that my computer can boot off of the USB. I tried Bootsect, but because I have a 32-bit OS currently and I have 64-bit OS installation parts on the USB, it doesn't work. How can I make my USB the main loader?
