<p>Prepare disk or target location where new system will
be installed. Follow steps describe how to create efi and
separate partitions such as; boot, root, swap, var, tmp,
user, home and srv.</p>
<h3>/boot/efi</h3>
<p>EFI System Partition, ESP type EF00. Partition
with between 500M and 100M is recommended for standard
installations.</p>
<pre>(parted) mkpart ESP fat32 2M 514M</pre>

</pre>
<h3>/boot</h3>
<p>Boot partition. Partition with 2G provides
room for bootable ISO.</p>
<pre>(parted) mkpart primary ext4 516M 2524M</pre>
<pre>
(parted) align-check optimal 2
</pre>
<h3>/</h3>
<p>Root partition with 2G is used in this example since i
usr and var are mounted on other partitions</p>
<pre>(parted) mkpart primary ext4 2548M 4564M</pre>
<pre>

<h3>Swap (ram)</h3>
<p>Swap partition with same memory as ram, example with
4G. Other swap partitions can be added later for port
build on ram.</p>
<pre>(parted) mkpart primary linux-swap 4568M 8576M</pre>

<p>Var partition with 2G;</dd>
