    Mixing GPT and MBR disks Win10

    Specs in sig. My Win10 1703 is on a MBR SSD, while my data HD is GPT. I'm considering adding another GPT SSD.

    Are there any problems with such mixing of partition styles?

    Lugh,

    There is no technical reason you can't do this or that it should have any problems.

    Personally, YMMV, I'd convert the boot drive to GPT and then enable Secure Boot as you have a new machine. This is just one more protection against the bad guys, layers and layers of security is the best defense!

    See this Article on how to do this w/o reinstalling Windows.

    Of course you'll make a full Image Backup of your drive before attempting anything like this!

    EDIT: Here's an even better article!

    I have never had or heard of problems.

    Just because you don't know where you are going doesn't mean any road will get you there.

    That's a v good article RG, looks clear and comprehensive. I ran…
    Code:
    mbr2gpt /validate /allowFullOS
    …successfully, so I should be good to give it a go once I finish loading my main programs.
