Convert mbr to gpt in Windows server 2022 without losing data

This video shows 2 ways to convert MBR to GPT in Windows Server 2022/2019 without losing data. 1 method is running MBR2GPT command to convert system disk from MBR to GPT. Another method is running NIUBI Partition Editor to convert data only disk to GPT.

After running the command and rebooting I got “no bootable device” (the device was a test site so no important information was lost)
Any advise?
