    Already did that. I am able to choose Windows 7 when prompted to choose an OS.
    However, the problem now is I can't run Windows 7... it brings me to a black screen with the message "cannot boot windows 7. autocheck not found"

    I tried Repair via Windows 7 disk installer, but it only detected my Windows 10, which it rightfully declined to repair.

    I tried syspreping the Windows 7 installation. It failed.
    Since it's very troublesome to dual boot a Windows 7 OS on a Windows 10 laptop, I calling it quits.

    FYI. Unlike Win8/10. It is easy just to create a backup image then restore to the new PC, you'd get a screen: getting your devices ready... then Windows will re-install all the drivers needed. Doing this with Windows 7 will result in BSOD. In addition, your new PC probably set up with UEFI partition scheme and AHCI enabled so you must re-install Windows 7 with SP1 in UEFI mode for it to work.

    If the Windows 7 that you transferred is a full retail copy, then:
    In Windows 10, the Windows 7 partition should have been assigned a drive letter. Let's say it got G:\. Right click on the start icon in Windows 10. Select Command Prompt (Admin). In the Command Prompt (Admin) window enter:

    BCDBOOT G:\Windows /d /addlast

    The path in red will be to the drive letter and Windows folder of the Windows 7 partition. Also recommend turning off Windows 10 fast startup:
    Fast Startup - Turn On or Off in Windows 10 - Windows 10 Forums

    Restart the computer.
    I'll have to re try that BCDBOOT command on a laptop. Let's see how it turns out.

    Yes, at times its booting issue but a lot of times Drivers/ GOP support etc.

    Is there any way to "force UEFI mode install" when you installed the Win 7 to partition using DISM:
    i.e. DISM /Apply Image - Or it would depend on the bcdboot commands after the DISM apply?

    Thanks. But, this method does not say anything about DISM based Wn 7 installation and how to enable it to boot/ run via UEFI mode? Thats kinda what i was asking.
