<span class="application">Mageia</span>.
</p>
<p><a name="doPartitionDisks-pa2"></a>The options available from
the list below will vary depending on your particular hard drive(s) layout
and content.

<p><a name="doPartitionDisks-pa3"></a></p>
<div class="itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<p><a name="doPartitionDisks-pa4"></a>Use Existing
Partitions
</p>
<p><a name="doPartitionDisks-pa5"></a>If this option is

and may be used for the installation.

<li class="listitem">
<p><a name="doPartitionDisks-pa6"></a>Use Free Space

<p><a name="doPartitionDisks-pa8"></a>Use Free Space on a
Windows Partition
</p>
<p><a name="doPartitionDisks-pa9"></a>If you have unused
space on an existing Windows partition, the installer may offer to use
it.
</p>
<p><a name="doPartitionDisks-pa10"></a>This can be a useful
way of making room for your new Mageia installation, but is a risky
operation so you should make sure you have backed up all important
files!
</p>
<p><a name="doPartitionDisks-pa11"></a>Note that this
involves shrinking the size of the Windows partition. The partition
must be "clean", meaning that Windows must have closed down correctly
the last time it was used. It must also have been defragmented,
although this is not a guarantee that all files in the partition have
been moved out of the area that is about to be used. It is highly
recommended to back up your personal files.
</p>
<p>With this option, the installer displays the remaining Windows
partition in light blue and the future Mageia partition in dark blue
with their intended sizes just under. You have the possibility to
adapt these sizes by clicking and dragging the gap between both
partitions. See the screen-shot below.

<p><a name="doPartitionDisks-pa14"></a>Note! This will

</p>

<p>The installer will share the available place out according to the
following rules:
</p>
<div class="itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<p>If the total available place is lower than 50 GB, only one
partition is created for /, there is no separate partition for
/home.
</p>
</li>
<li class="listitem">
<p>If the total available place is over 50 GB, then three
partitions are created
</p>
<div class="itemizedlist">
<ul class="itemizedlist">
<li class="listitem">
<p>6/19 of the total available place is allocated to / with a
maximum of 50 GB
</p>

<li class="listitem">
<p>1/19 is allocated to swap with a maximum of 4 GB</p>

<li class="listitem">
<p>the rest (at least 12/19) is allocated to /home</p>
</li>
</ul>
</div>
</li>
</ul>

<p>That means that from 160 GB and over of available place, the installer
will create three partitions: 50 GB for /, 4 GB for swap and the rest for
/home.

<p>Some newer drives are now using 4096 byte logical sectors, instead
of the previous standard of 512 byte logical sectors. Due to lack of
available hardware, the partitioning tool used in the installer has not
been tested with such a drive. Also some ssd drives now use an erase block
size over 1 MB. We suggest to pre-partition the drive, using an
alternative partitioning tool like gparted, if you own such a device, and
to use the following settings:
</p>
<p>"Align to" "MiB"</p>
<p>"Free space preceding (MiB)" "2"</p>
<p>Also make sure all partitions are created with an even number of
megabytes.
