I have linux mint 17.1 currently and i bought windows 8.1. I dont have a cd drive so i tried installing it by usb. I used a program to create the iso from the cd on my brothers windows computer. When i boot to windows on my computer i get a message saying that the computer started using the windows installation media. remove the installation media and restart even though i havent installed it on my computer yet. When i try advanced settings it says that my hdd is formatted in gpt or something. Any solutions?
