    <title>Introduction</title>
    <para>
    The <application>&app;</application> application is the GNOME Partition
    Editor for creating, reorganizing, and deleting disk partitions.
    </para>
    <para>
    A disk device can be subdivided into one or more partitions.
    The <application>&app;</application> application enables you to
    change the partition organization on a disk device while
    preserving the contents of the partition.
    </para>
    <para>
    With <application>&app;</application> you can accomplish the following
    tasks:
      <itemizedlist>
        <listitem>
          <para>
          Create a partition table on a disk device.
          </para>
        </listitem>
        <listitem>
          <para>
          Enable and disable partition flags such as boot and hidden.
          </para>
        </listitem>
        <listitem>
          <para>
          Perform actions with partitions such as create, delete,
          resize, move, check, label, copy, and paste.
          </para>
        </listitem>
      </itemizedlist>
    </para>
    <caution>
      <para>
      Editing partitions has the potential to cause LOSS of DATA.
      </para>
      <para>
      The <application>&app;</application> application is
      designed to enable you to edit partitions while
      reducing the risk of data loss.
      The application is carefully tested and is used
      by the &appname; project team.
      However, loss of data might occur due to software bugs,
      hardware problems, or power failure.
      </para>
      <para>
      You can help to reduce the risk of data loss by
      not mounting or unmounting partitions outside of
      the <application>&app;</application> application while
      <application>&app;</application> is running.
      </para>
      <para>
      You are advised to BACKUP your DATA before using
      the <application>&app;</application> application.  This is
      especially true for encrypted data where all of the data can
      become permanently inaccessible after a failure.  Please refer to
      <ulink type="http" url="https://gitlab.com/cryptsetup/cryptsetup/wikis/FrequentlyAskedQuestions">The Cryptsetup FAQ</ulink>
      for backup and recovery advice of encrypted data.

                Number on the Windows system partition, normally C:,
                might invalidate the WPA key.  An invalid WPA key will

                In rare cases, a partition that is present

                Changing the UUID is only required after copying a

          The copy of the partition has the same file system label
          and Universally Unique Identifier (UUID) as the source
          partition.
          This can cause a problem when booting, or when mount actions
          use the file system label or UUID to identify the partition.
          </para>
          <para>
          The problem is that the operating system will randomly
          select to mount either the source, or the copy of the
          partition.  For example, on the first mount action the
          source partition might be mounted.  On the next mount action
          the copy of the partition might be mounted.  Over time this
          random nature of partition mounting might make files seem to
          mysteriously appear or disappear depending upon which
          partition is mounted.  Random mounting of the source or the
          copy of the partition might also cause severe data
          corruption or loss.

              <para>
              Use GParted to list the partitions on your disk device.
              Look for a partition that contains your GNU/Linux / file
              system.  This Linux partition will likely use a file
              system such as ext2, ext3, ext4, or btrfs.

                If the / partition is on LVM then the Logical Volume
                Manager must be active.  LVM can be started with the

                <para>
                With LVM, the equivalent of a disk partition is a
                Logical Volume.  Logical Volumes can be listed with
                the command:

              If you have a separate /boot partition, for example at
              /dev/sda3, then an extra step is required.  Mount the
              /boot partition at /tmp/mydir/boot by entering (as
              root):
              <screen><prompt># </prompt><command>mount</command> <replaceable>/dev/sda3</replaceable> /tmp/mydir/boot</screen>

                If you do not know whether you have a separate boot
