Im moving back to Windows, and maybe ill dual boot with Ubuntu afterwards. Anyway, I have that .iso file sitting in my documents. My laptop doesn't have a disc drive, which is really unconvenient for a laptop that said in the description, "Runs on ubuntu, can easily install Windows". So im going to need to either find a way to install it on a flash drive or do it without using anything. I am limited to this computer only, so I can't use another computer to install the .iso file on the USB or anything. Im going to need to do it here. So, help?
