How do I convert MBR to GPT without losing data?
I'm currently facing an issue where I need to convert a disk from MBR (Master Boot Record) to GPT (GUID Partition Table) without losing any data stored on it. The disk in question contains important ...
It seems MBR2GPT doeson't work for me while I'm trying to convert main disk from mbr to gpt, when validating the disk in Windows PE using "mbr2gpt /validate" I get the following output:
MBR2GPT: Attempting to convert disk -1
MBR2GPT: Retrieving layout of disk
Anybody knows this error and how to fix it?

It should be easy to fix, first, check your disk configuration by diskpart command, like “list disk”, it will list your boot and you can see GPT or MBR column.
If it isn't GPT, then try the command "mbr2gpt /disk:{number you found} /validate", so for example "mbr2gpt /disk:0 /validate".
but if you're not familar with command, and there is a risk of doing in this way, you can use some professional MBR to GPT convreter with UI.
