After I install WINDOWS 7 under PE, restart the computer will be stuck in WINDOWS start page; I'm Win10 computer itself, and then want to install dual system, in another drive an original Windows 7 system, the system is the MSDN download ISO package, there will be no problem, I also tried to install 2 are Win10 is ok, I see online say because CPU8 generation does not support to install Windows 7 start, there are some, because Windows 7 is not updated, peripheral driver doesn't support or some software can't use, want to know what causes the problem really is,
