I recently put in a new hard drive into my old pc to have it work again. I bought windows 10 for it. I have a h81m-e33 and I need help installing the windows 10 from a USB. It's saying "reboot and select proper boot drive." It's recognizing my hard drive and optical drive but I need it to install the Windows 10 from the USB. The bios menu is very bad and non-user-friendly and hard to understand. It has UEFI which I really don't know what to do with it. If you could help at all, it would be great!
