Is there really no way to restore an x86 image over an x64 install?

    OK back to basics.

    Run 64 bit version and open a command prompt and run

    diskpart

    list disk

    and post image.

    Can't do that anymore; as I described in my original post, I ended up doing a full disk clean-install of x86 windows, and then I was able to start x86 Recovery USB and restore the x86 image. So I accomplished my goal, and now I'm hoping to learn how to do it more simply next time.

    How about if I put it this way:
    (1) Can you launch a 32 bit recovery environment on a computer that has x64 Windows installed?
    (2) When running in a 64 bit recovery environment, can you restore a 32 bit image?

    As is mentioned on sites where downloads of updates for Windows can be had it is always stated to get the proper version as what is installed, either 32-bit or 64-bit. Basically it all comes down to those two can't be mixed in any way, shape or form.

    32-bit programs can be installed in 64-bit Windows but not the other way around.

    As we have tried to explain, it depends on if original OS was UEFI or legacy bios.

    You have to run Recovery from flash drive.
    You cannot run recovery to an OS drive from within windows

    So if pc was using legacy bios originally

    1) 64bit over 32bit - yes

    2) 32bit over 64bit - yes

    If PC was using UEFI

    3) 32bit over 64 bit - no as pc will not support both 32bit and 64bit in UEFI. Normally only 64bit UEFI is supported. You have to wipe drive and install as legacy bios.

    4) 64bit over 32bit - not even an option as (apart from some special case tablets) 32bit UEFI does not exist.

    So to restore 32bit over 64bit

    Put pc in legacy bios mode

    Boot from Macrium usb drive.

    Click on c prompt in bottom left corner

    Run:-

    diskpart

    list disk

    select disk n (n is number of drive, usually 0 - be sure to select right disk)

    clean

    exit

    exit

    Now restore 32bit version.

    That's it.
