Any Safe Way to Convert Windows to GPT Without Wiping All Data?

I wanted to activate SAM on a new pc but of course, it doesn't work in legacy mode, which I need to boot into my MBR Windows installation. I know Windows has a built-in tool to convert MBR to GPT but apparently, it wipes your data. Any other suggestions?

According to your description, your computer has just been upgraded, which is changed from legacy boot mode to UEFI boot mode. It's the reason that you cannot boot your Windows system on the MBR disk. The built-in tool of Windows, such as Dispart and Disk Management, will wipe all your data on this disk. Therefore, do a full backup before using them, or you will lose all your important data, and the process is irreversible. Don't worry. We will teach you a safe method by which you can convert Windows to GPT without wiping all data. Keep reading and find more details.
