I have a windows 7 iso that I put on a USB drive. I got a new hard drive, booted to bios successfully, Changed priority to the sandisk USB and pressed enter, says "reboot and select proper boot device or insert boot media..."

What am I doing wrong?

I bought this PC from Craig's. I've done this before. My buddy did it for me last time though. He said the OS is in the thumb drive and should just plug and play. But its not. And he's in the army and isn't here to help like last time. I used another program called isotousb and it worked. I did that cus I was told the USB wasn't bootable. That program worked but its still saying insert proper drive etc etc when I try to boot from it
