    utility to convert MBR disk with Windows partitions to GPT?


    Does this utility exist?

    I've tried Minitool's free version, which claims to support MBR to GPT conversion, but I got a warning that the disk would not be bootable.

    I downloaded a trial of the paid Easeus partition manager and when I tried that conversion, I got an error message telling me to contact support.

    Any suggestions, besides the one where you copy off all partitions to another drive, then do the conversion, and then copy all partitions back?

    Converting drive to gpt without losing data is easy enough. Your issue is that the partitions will be set up as legacy bios, and to use gpt on OS drive, you need to convert install to uefi instead.

    It is doable but takes a little work.
