I am trying to boot Win 7 on a separate drive onto a Win 8.1 pc. I turned on legacy boot, disabled secure boot and turned off fast boot. EasyBCD shows both drives and boots to Win 8.1. Win7 locks up and does nothing, even after hours. I tried booting from the Win 7 disk and get an error this disk is for the wrong machine. I bought EasyRepair for Win 8 but that does not seem right now since Win 8.1 boots fine. Any help is appreciated.
