Please help me install win 10 on a machine that already has win 7 on it. i want everything wiped because i bought this machine incl. hard drive from a friend and then upgraded it myself, but i dont want any of his stuff on my computer, but also i want win 10, when i run the normal client it says that my version of win 7 isn't legit so i have to put in a product code from when i bought it. Is there anything i can do, if so please help me !
