That doesn't really answer the question...
First, there is no such thing as "GPT partition". GPT is a partitioning scheme, therefore an attribute of a disk, not a partition. Partitions can be created on an MBR partitioned disk, or a GPT partitioned disk. The partitions on such disks are neither "MBR partitions", nor "GPT partitions"... just "partitions on an MBR disk" or "partitions on a GPT disk".
And Windows may have installed EFI\Microsoft on the EFI on mSATA or on the EFI on the SATA SSD.
You should check the actual content on each EFI partition.
