I bought a new computer they installed linux mint 17.3. Now I want to relpace linux with windows 8.1. I tried for that but unfortunately I couldn't do that. It is is because of partition problem. Now I want to unpartition the linux installed system disk. I searched in internet and follow the path using command prompt, command fdisk is working after that I entered command p but unfortunately commands like p, m (help) are not working. How can I unpartition the linux installed disk for replacing linux with XP. Please help me.......or please give me a new idea for replacing linux with windows...........
