So, for my new gaming pc, I had to get windows of course and the way I was gonna do that was with a usb stick and an iso. But, I ran into some problems. First, being I couldn't even download the frickin windows iso setup tool. The reason why is because I have no windows computers. My dad only buys macs and nothing else (i'm 14) so I had to find another way. I tried using boot camp and selecting the make a windows boot drive but, on el capitan, there is no option to do that, only partitions -_- So then, I decided to do terminal, there wasn't any other direct way in osx. I followed a tutorial on how to do this and after 3 tries and 2 hours, the thing didn't even work partly. The guy who was doing it was trying to make a windows boot drive with the linux method. Then, I found in the comments that a guy knew that this was wrong and knew how to do it correctly, so after that, I got stuck on erasing the drive and formatting it to MS-DOS FAT and had to do a terminal command. Then, some of the files in the windows 10 iso didn't work either. So I had to zip them and un-zip them in the flash drive folder. Then, after I was finally done, I plugged it into my computer, I got this message saying Non-system disk Press any key to reboot. Is there any thing that I can do? Or would I just have to restart. Really hope those 7 hours of figuring this out weren't for nothing.
