Failed while updating the boot sectors for disk0 partition1
instead of finding out where the actual system store resides.My BIOS BCD had invalid entries so MBR2GPT rightfully complained that it couldn't find the non-existent recovery volume.
However, I found out what was the main reason for the problem and solved it.
I'm also using Windows 10 Creators update at the moment.
I tried and I got an error about "not finding the OS partition".
You will need to delete this partition or resize it in another utility.
You should have interpreted the above message to mean you were using the wrong command.
