When creating a fresh partition table, certain considerations may be in order:

       *      For data (non-boot) disks, and for boot disks used on BIOS-based computers with GRUB as the boot loader, partitions may be created
              in whatever order and in whatever sizes are desired.

       *      Boot  disks  for  EFI-based  systems require an EFI System Partition (gdisk internal code 0xEF00) formatted as FAT-32.  The recom‐
              mended size of this partition is between 100 and 300 MiB.  Boot-related files are stored here. (Note that  GNU  Parted  identifies
              such partitions as having the "boot flag" set.)

       *      Some  boot  loaders  for BIOS-based systems make use of a BIOS Boot Partition (gdisk internal code 0xEF02), in which the secondary
              boot loader is stored, possibly without the benefit of a filesystem. (GRUB2 may optionally use such a partition.)  This  partition
              can typically be quite small (roughly 32 to 200 KiB), but you should consult your boot loader documentation for details.

       *      If  Windows  is  to boot from a GPT disk, a partition of type Microsoft Reserved (gdisk internal code 0x0C01) is recommended. This
              partition should be about 128 MiB in size. It ordinarily follows the EFI System Partition and  immediately  precedes  the  Windows
              data  partitions. (Note that old versions of GNU Parted create all FAT partitions as this type, which actually makes the partition
              unusable for normal file storage in both Windows and Mac OS X.)

       *      Some OSes' GPT utilities create some blank space (typically 128 MiB) after each partition. The intent is  to  enable  future  disk
              utilities  to  use  this space. Such free space is not required of GPT disks, but creating it may help in future disk maintenance.
              You can use GPT fdisk's relative partition positioning option (specifying the starting sector as '+128M', for  instance)  to  sim‐
              plify creating such gaps.
