Is it possible to change MBR to GPT without formatting the disk?

Question

Windows

I have a disk with 2 partitions. The disk is in MBR, the system is already installed on 1 partition (Windows 7), and the second partition is empty. As far as I know, it is impossible to remake a pure GPT partition, and without this, Windows 10 does not want to be installed. Any options? Thanks in advance.

Answer 1

It seemed to me that you mentioned "formatting" in the sense of "destroying data", and not in the sense of "partitioning the disk file system". If this is so, then I bring to your attention that advanced partition managers can convert GPT-> MBR and vice versa without losing data (in any case, Paragon and AOMEI know how to do this for sure - I checked it myself, and more than once).
Where to get them? It is not at all necessary to buy and install them in your OS for a one-time need. It is enough, after downloading the image, to create some kind of tool-recovery LiveDVD / LiveUSB containing the popular set of 2k10 utilities (it has these partition managers and much, much more) - this thing will come in handy a hundred times later for a variety of reasons, not only for your current problem.
If you find it difficult to choose, I recommend MultiBoot - I use it myself.

Answer 2

Some programs for partitioning discs can convert)
