    Converting W10 System Disk from MBR to GPt


    For some reason my W10 System Disk (SSD) is set up as an MBR Disk. My separate Data disk (HDD) is GPT. I know how to convert the System Disk to GPT using Minitools Partition Wizard. If I do that to the SSD will I loose the W10 installation? And is there any advantage to doing that conversion?

    Thank you.
