    mantra,

    I thought we did this in the past. If you desire, you can have ten Win8.1 and ten Win10 on the same HD. Installed in MBR mode and booting with BIBM.

    You can do a similar multi-boot (not with BIBM) with the OS installed in UEFI mode. You choose the boot OS by manipulating the EFI system partition.

    These OS are independent, unlike a Microsoft dual boot.

    mantra,

    There are some great tutorials here on multi-booting with BIBM. I can fine tune any questions you have.

    None of the installed OS will see the other OS. They can't interact and you can delete any at your convenience.

    I took the chicken way to do this. I have separate images for each OS, and just restore the one I want. Keeps things simple

    hi
    i used an empty ssd on sata port 2 and w10 create a dual boot on sata port 1
    hope there is a way to do it without disconnect the drive via hardware

    mantra,

    BIBM can do this easily. What issues are you having with BIBM?

    @mantra,

    If you feel up to it you do not need any third party tool to have two OS running on the same HDD or Partition and completely isolated form each other as well. Last Friday I installed Windows 10 on my laptop for the first time. I created a virtual Hard Disk (VHD), on one of my partitions, from disk management of Windows 7, and then installed Windows 10 on the VHD. This way on bootup I can choose whether to boot into Windows 10 or Windows 7. A VHD is created as a file on your HDD and and is completely isolated from your regular OS and other software.

    Let me know if you want to try this approach.

    No it does not. It is not like Virtualbox or Vmware Workstation where you are running a guest OS inside a host OS i.e. running two OS at the same time; thus slowing your system down.

    When you add a VHD to your system, it acts like a regular disk and when you boot into the OS on the VHD, at that time, you are only booted into just one OS. The other OS is isolated and switched off.
