How to install SLES 15

SUSE Linux Enterprise Server 15 sp2 is a Linux operating system which focuses its attention mainly on the server, mid-range and mainframe market. SLES as it is commonly known is mainly used by larger organisations/Enterprises. SLES 15 Service Pack 2 is available to download as a 60 day evaluation. It can be downloaded for many platforms including x86, AMD64/Intel64, System Z, IBM Power and Itanium editions. The evaluation period is normally for a period of 60 days. This gives you access to the latest packages and patches. Larger evaluation periods are available for larger platforms. After the initial evaluation period, you will need to purchase a license agreement for continued support of your operating system.

Installing SLES sp2

To try SLES 15, click on the link below and follow the Download Instructions: Download SUSE Linux Enterprise Server

At the above site, there are multiple different images available. The smaller images are generally for installing if you have an active network, and the larger full images are for offline installations. In the example, that follows, I have selected the "SLE-15-SP2-Online-x86_64-QU1-Media1.iso" edition. Once you have downloaded your chosen "iso" image of SLES, you will need to burn this image to a DVD. For software that can do this, you can search for "dvd iso burning software" in the search box provided above. Your computer may already have CD/DVD burning software already installed such as "Brasero, K3B, Nero, CDBurnerXP or Roxio". Once you have burned your chosen "iso" image of Leap to your Media, you will need to place your DVD disc into the DVD drive of the target system and reboot your system. As your computer system reboots, you will need to press the appropriate key to access your system's BIOS settings. On many systems this key will be "F8", "F11" or "F12". Most systems will display a message indicating which key needs to be pressed. Once you have access to your system's BIOS settings, you will need to modify the boot order of your system to boot from CD/DVD first. Once this change has been made, you can now reboot your system and follow the installation guide below. If you are installing into a Virtual Environment, simply copy the downloaded "iso" image to the relevant location provided by your software.
