Installation

Insert the target device and ensure it is not mounted. (If it is, try umount /dev/sdXN.)

Upstream recommends use of fdisk(8). The partitioning process is as follows: 

fdisk /dev/sdX

  1. Ensure that the device is not using a GPT partition table. This would be listed under Disklabel type. (Press p to list the partitions.) The correct value is dos, not gpt.

  2. Create new partition table with one FAT32 partition

    1. d Delete all partitions (and repeat as needed)

    2. n Create a new partition

    3. p A primary partition

    4. 1 Partition number 1

    5. Use defaults for first and last cylinder (press [Enter] twice).

    6. t Change partition type

    7. c Partition type (Win95 FAT32/LBA)

  3. Ensure that the primary partition is bootable. This is marked by an asterisk (*). (Press p to list the partitions.) To make the partition bootable...

    1. a Set the boot flag on a partition

    2. 1 Partition number 1

  4. w Write your changes to the device

For more general advice regarding partitioning, see here.

Format the new partition with: 

mkfs.vfat /dev/sdX1

Note that mkfs.vfat and mkdosfs are the same.

Finally, dd(1) the ISO onto the device. Or for a Raspberry Pi, copy the boot binaries onto the device.
