Before you begin

Obtain 1 USB Flash drive (installation USB drive must be minimum 4 GB).
Download latest Rufus tool onto a local Windows PC if not already installed. Do not use the Portable version of Rufus.

Note:
The below image is an example only and shows a previous version of Rufus.
Download the corresponding ASP R7.x R660xs ISO installer file (reference PCN2182 and ASP 7.x Release Notes for the latest available downloads) from PLDS to the local Windows PC to be used for creating USB installation media.

Important:

Starting with ASP R7.0, there are two distinct ISO images available—with and without LUKS encryption. Choose carefully before proceeding. Once the software is installed, you cannot enable or disable encryption. Switching between states requires a complete fresh installation.

Insert the 4GB or larger USB flash drive into your Windows PC where the ISO installer file was downloaded.
