Microsoft wants the GPT Disks partitions layouted as: Extensible Firmware Interface System Partition (ESP) ~100MB OEM Partition (optional) Microsoft Reserved Partition (MSR) [Drive <16GB - MSR = 32MB, Drive >= 16GB - MSR = 128MB] - used to reserve space that is later broken in to smaller partition for use by meta data (i.e. dynamic disks) Data Partitions (FAT, NTFS, ...) If these partitions (ESP, OEM and MSR) were mixed in with the Data Partions, then you would be unable to grow the filesystems.
