    Windows 10 x64 Home

    How to dual boot to x86 OS when Windows 10 is already installed?

    I have a Acer Aspire XC-603G desktop upgraded to Windows 10 64bit Home (no Hyper-V). I want to run 16 bit software that is incompatible. I would like to dual boot with Vista x86 (gave away my XP). From what I understand, you must load the older version first due to Windows 10's MBR. Can I backup/clone Windows 10 partition, reformat and repartition the HDD, install Vista in first partition, then restore Windows 10 to the second partition? I'm thinking I'll need a fresh Windows 10 install. Or is there a simpler way? The only other way I see is to buy the Pro upgrade to get Hyper-V. And if I did the latter would it really be compatible with my Windows 95 16bit ImageReader Scanner software? Thanks

    Windows 8.1, Win10Pro

    Or is there a simpler way?
    Don't know if it's simpler -- you have to make that call.

    You could do the following:
    1) make room on the drive for Vista
    2) install Vista
    3) reboot, but into Win10
    4) download and install EasyBCD from NeoSmart Technologies
    5) open EasyBCD, click the Add New Entry button, in the Operating Systems section, use the pulldowns and enter info to add Vista as a boot option, click the Add Entry button, save the results

    When you reboot, you should get an OS selection screen, with entries for Vista and Win10.

    But what about the boot record?
    Ref: Install more than one operating system (multiboot) - Windows Help


    • You must install the older operating system first, and then install the more recent operating system. If you don't (for example, if you install Windows Vista on a computer already running Windows 7), you can render your system inoperable. This can happen because earlier versions of Windows don't recognize the startup files used in more recent versions of Windows and can overwrite them.

      May try Oracle VirtualBox.
