#### 2.4.12 set

Command: set number flag state

  Changes a flag on the partition with number number. A flag can be either “on” or “off”. Some or all of these flags will be available, depending on what disk label you are using:

  ‘`bios_grub`’

    (GPT) - Enable this to record that the selected partition is a GRUB BIOS partition.

  ‘`legacy_boot`’

    (GPT) - this flag is used to tell special purpose software that the GPT partition may be bootable.

  ‘`boot`’

    (Mac, MS-DOS, PC98) - should be enabled if you want to boot off the partition. The semantics vary between disk labels. For MS-DOS disk labels, only one partition can be bootable. If you are installing LILO on a partition that partition must be bootable. For PC98 disk labels, all ext2 partitions must be bootable (this is enforced by Parted).

  ‘`lba`’

    (MS-DOS) - this flag can be enabled to tell MS DOS, MS Windows 9x and MS Windows ME based operating systems to use Linear (LBA) mode.

  ‘`root`’

    (Mac) - this flag should be enabled if the partition is the root device to be used by Linux.

  ‘`swap`’

    (Mac) - this flag should be enabled if the partition is the swap device to be used by Linux.

  ‘`hidden`’

    (MS-DOS, PC98) - this flag can be enabled to hide partitions from Microsoft operating systems.

  ‘`raid`’

    (MS-DOS) - this flag can be enabled to tell linux the partition is a software RAID partition.

  ‘`LVM`’

    (MS-DOS) - this flag can be enabled to tell linux the partition is a physical volume.

  ‘`PALO`’

    (MS-DOS) - this flag can be enabled so that the partition can be used by the Linux/PA-RISC boot loader, palo.

  ‘`PREP`’

    (MS-DOS) - this flag can be enabled so that the partition can be used as a PReP boot partition on PowerPC PReP or IBM RS6K/CHRP hardware.

  ‘`DIAG`’

    (MS-DOS) - Enable this to indicate that a partition can be used as a diagnostics / recovery partition.

  The print command displays all enabled flags for each partition.

  Example:

      (parted) set 1 boot on

  Set the ‘`boot`’ flag on partition 1.
