以下の方法で EFI パーティションを作る。
sudo parted /dev/sdh mklabel gpt
sudo parted /dev/sdh mkpart efi 0% 512M
sudo mkfs.fat -F32 /dev/sdh1
sudo parted /dev/sdh set 1 esp on確認
# sudo fdisk -l
Disk /dev/sdh: 1.86 TiB, 2048408248320 bytes, 4000797360 sectors
Disk model: P80-2TB
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
