Worked on windows 10 but error on windows 7 ?

[mrtonn]

hi,
recently I'd install windows 10 on HDD and its worked, now i try windows 7 x64 ultimate on same HDD, but when i try to boot it, showing error "windows failed to start a recent hardware or software change might be the cause" and show option to boot in safe mode, safe mode with network, etc, i've try all options and just got same error.
please help me to fix it  

Thanks.

Did you install Windows 7 x64 ultimate directly from an ISO file? And did you get this error when you first boot from the HDD?

Yes, is that wrong ?
