Can I Recover Lost Data After Disk MBR to GPT Conversion

"I tried to install a new application on my computer, but the application requires GPT for installation and my disks are MBR. As I can't convert the system disk, so I made the change on the second hard drive.

By following a tutorial guide online using Disk Management, I found that the partitions on the second disk vanished from my computer after the conversion. I have stored quite a lot of important data and files in that partition. Can I recover lost data after disk MBR to GPT conversion?"

Cause of partition and data loss due to disk conversion

Some users don't know how their partition and data get lost after disk conversion - MBR to GPT or GPT to MBR. Actually, it's a common issue. As you can see from the below image, the conversion option is not available in Disk Management:
