Install Windows 7 on new Windows 8 laptop

Is there a way to install Windows 7 on a separate partition on a new Windows 8 laptop?

I found a guide that shows how to downgrade by turning off secure boot in UEFI but that doesn't work for me. Flash drive LED lights up but nothing on screen and it boots into Win 8. So I'm guessing the file system has something to do with it but I'm unfamiliar with UEFI and Win 8 file system.

Does anyone have a simple solution (perhaps using EasyBCD) that doesn't involve reformatting and installing Win 7 and then Win 8? I prefer not to go that route because of the complicated guides that I've seen for backing up Win 8 authentication, not to mention I don't have a Win 8 disc/iso.
