    this was what I tried originally however was getting errors saying to convert MBR to GPT then after doing that had a lot of other problems preventing windows from being installed after goggling and following threads with same error messages left me at start of this thread.
    currently running diskpart clean all on the HDD that is setup as MBR and will report back on what happens after a fresh start.

    Windows Setup will want to set up the hard drive for the same mode of booting that Windows setup was booted with. Boot Windows Setup in UEFI mode, it will want to set up the HDD for GPT partitioning and UEFI booting. Boot Windows Setup in Legacy or CSM mode and it will want to set up the HDD for MBR partitioning and legacy booting. Boot mode is determined by the bios, obviously.

    Another option may be to do the install, then do a sysprep, then move it?


    In most cases, if the BIOS is UEFI, and the install media supports UEFI, you should get two boot options listed for your install media. One with UEFI in front of it and one without. The one with no UEFI in the description will be legacy mode..

    Could not install Windows onto the HDD after the Clean All as MBR wiped the USB and set it up again as you mentioned it should display as 32GB even as greater size and it was showing as 54GB in diskpart.
    After this it seems I am able to install (having changed to legacy within BIOS under an option within advanced. Thanks for all your help seems I just took a wrong turn when I began before this playing with the HDD instead of the BIOS settings

    As long as all the computers in question have been upgraded once to Windows 10 and have digital entitlements, there is really no need to run sysprep before moving the hard drive to a new computer. Windows 10 adjusts to new hardware very well without running sysprep.

    I agree, it didn't appear work that way for him though, that's why I suggested it as an option.
