Okay so I Just built a new gaming PC. I live in Quebec (A french speaking province in Canada) and I went to the best buy to buy windows 10. They told me they only have french copies but that I could change the language settings once I get through the install. Well i've installed it and trying to change the language settings has been a nightmare. I've got it that some stuff is written in english, but mostly everything is still in french. If no one has any suggestions on how to universally change the language of my operating system, I guess the next step would be to completely erase my hard drive and go purchase an actual english copy. How do I erase my hard drive and just have the computer boot straight to the BIOS again and start over?
