I need to revert back to Windows7 for some reasons, I have Ubuntu 14.04 installed. I have extracted my windows7 iso and copy it to a pen drive but when I restart my laptop I cannot boot it, F12 wont work.
I've been searching around but I don't understand how to fix this issue, what is the simplest way to go back to Windows7?
winusb
