dialog.
</para>
</listitem>
<listitem>
<para>
Optionally select a different partition table type from the
list.
</para>
<note>
<para>
The default partition table type is
<guimenuitem>msdos</guimenuitem> for disks smaller than 2
Tebibytes in size (assuming a 512 byte sector size) and
<guimenuitem>gpt</guimenuitem> for disks 2 Tebibytes and
larger.
</para>
<para>
See <xref linkend="gparted-specify-partition-type"/> for
<guimenuitem>msdos</guimenuitem> partition table
limitations.
</para>
</note>
<note>
<para>
To use a disk without a partition table, choose
<guimenuitem>loop</guimenuitem> to create a virtual
partition that spans the disk. Then format to the
desired file system.
</para>
<para>
See <xref linkend="gparted-format-partition"/> to format
a virtual partition with a file system.
</para>
</note>
<caution>
<para>
Many operating systems recognize
<guimenuitem>gpt</guimenuitem> and
<guimenuitem>msdos</guimenuitem> partition tables, but
do not recognize all types of file systems. This lack
of file system recognition means that using a disk
without a partition table involves more risk. For
example, some operating systems might prompt to format an
unpartitioned disk if the file system is not recognized.
</para>
</caution>
</listitem>
<listitem>
<para>
Click <guibutton>Apply</guibutton> to create the new partition table.
The application writes the new partition table to the disk device.

<caution>
<para>
If you delete a logical partition, then all existing logical
partitions after the deleted logical partition will
experience changes in device names.
</para>
<para>
For example, an extended partition contains four logical
partitions A, B, C, and D. These logical partitions are accessed by the
operating system as follows:
</para>
<itemizedlist>
<listitem>
<para>
Partition A as /dev/sda5.

</para>
</listitem>
<listitem>
<para>
Partition D as /dev/sda8.
</para>
</listitem>
</itemizedlist>
<para>
If partition B is deleted, then the remaining logical
partitions will be accessed by the operating system as follows:
</para>
<itemizedlist>
<listitem>
<para>
Partition A as /dev/sda5.
</para>
</listitem>
<listitem>
<para>
Partition C as /dev/sda6. Note the change in device name.
</para>
</listitem>
<listitem>
<para>
Partition D as /dev/sda7. Note the change in device name.
</para>
</listitem>
</itemizedlist>
<para>
Changes in a device name can cause problems if a
partition is mounted using a device name.
You can avoid the problem by using the file system label or
Universally Unique Identifier (UUID) of
the partition when mounting the partition.
</para>
<para>
Changes in a device name might adversely affect the
following files:
<itemizedlist>

<para>
Changing the UUID might invalidate the Windows Product
Activation key (WPA).
</para>
<para>
On FAT and NTFS file systems, the Volume Serial Number
is used as UUID. Changing the Volume Serial
Number on the Windows system partition, normally C:,
might invalidate the WPA key. An invalid WPA key will
prevent login until you reactivate Windows.
</para>
<para>
In an attempt to avoid invalidating the WPA key, on
NTFS file systems only half of the UUID is set to a
new random value. On FAT file systems, such a precaution
is not possible.
</para>
<para>
The WPA key should not be affected by changing the
UUID of data partitions or removable media partitions.
In rare cases, a partition that is present
at boot time might be an exception to this rule.
</para>
</warning>
<warning>
<para>
Changing the UUID when there is no need to do so might
cause a GNU/Linux system to fail to boot, or to fail
to mount a file system.
</para>
<para>
Changing the UUID is only required after copying a
partition. The UUID change is needed to prevent
duplicate UUIDs when both the source and the copy of
the partition are used on the same computer.
</para>
<para>
If boot or mount problems occur you might need to edit
configuration files, such as /etc/fstab, and
regenerate the grub menu to ensure that the correct
UUID is specified.

<caution>
<para>
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>
<para>
To avoid the problem you are advised to do one of the
following:
<itemizedlist>
<listitem>
<para>
After you have queued or applied the copy operation:
<orderedlist>

<para>
Change the UUID of either the source, or the copy
of the partition.
See <xref linkend="gparted-changing-partition-uuid"/>.
</para>
</listitem>

If the file system label is not blank then change

Use some other method to ensure that the source
partition and the copy of the partition are not used
on the same computer at the same time. For example,
if the copy of the partition is on a separate drive
then remove the drive from the computer.
