MBR2GPT Disk layout validation failed
When i try to run
mbr2gpt /validate /disk:0 /allowFullOS
i get the following output
MBR2GPT: Attempting to validate disk 0 MBR2GPT: Retrieving layout of disk MBR2GPT: Validating ...
I believe your recovery partition is not a primary partition, from what I can see. You can see the rest are primary and recovery seems to be a logical. mbr2gpt also doesnt support logical partitions either.
I believe mbr doesn't support more than 3 primary partitions.
Here is a suggestion, move the recovery content to primary partition and the remove the that partition and try again. Makesure backup the drives always.
I remember when I did mine, i did not have any recovery partition. Only had system reserved and os partition. Then added the un allocated space at end for validation to pass.
I also did the conversion using windows PE. I posted relevant links before for that method.
Hope this helps.

I only reenabled the recovery due to the problem that Windows told me that it cannot find a boot partition, then I only had 3 partitions, all primary. This did not work well either. Even with only 1 partition it did not work. And as seen in the screenshots, there is no systemreserved partition on my drive 0 from which I boot more or less any day. If you need additional information, or want me to post the screenshots again, please let me know. And as written before, it does not make any difference to the outcome of the error messages I receive, wether I run the commands from Windows, or winPE, the results are 100% the same! It is just easier to provide screenshots from the winOS instead of winPE, still same results.
I would be glad if you had any other ideas and thank you very much.
