MBR2GPT Help (Windows 10)

Looking to enable SecureBoot so I tried the MBR2GPT command and received an error that it could not validate. I've attached a screenshot of my Disk Manager. Perhaps it's due to my existing partitions? Or maybe it has to do with how limited my Boot drive is in regards to available storage? Looking for any next steps or help, as I'm extremely illiterate when it comes to this stuff.

    MBR-to-GPT conversion requires the disk to meet specific criteria, such as having only one primary partition or no recovery partitions.

    The error during mbr2gpt validation often happens because of existing partition or configuration issues, especially if your drive has certain partitions or structure that don't meet the tool’s requirements.
