1.2 Choosing the Installation Method
After having selected the installation medium, determine a suitable
installation method and boot option that best match your needs:
- Installing from the openSUSE Media
-
Choose this option, if you want to perform a stand-alone installation
and do not want to rely on a network providing the installation data
or the boot infrastructure. The installation proceeds exactly as
outlined in Section 1.3, The Installation Workflow.
- Installing from a Network Server
-
Choose this option, if you have an installation server available in
your network or want to use an external server as the source of your
installation data. This setup can be configured to use from physical
media (Floppy, CD/DVD, or hard disk) for booting or configured to boot
via network using PXE/BOOTP. Refer to
Section 1.2.1, Installing from a Network Server Using SLP,
Section 1.2.2, Installing from a Network Source without SLP, or
Section 1.0, Remote Installation, (↑ Reference ) for details.
- Installing with instlux from Windows
-
Choose this installation option, if you prefer a smooth transition
from using Windows to Linux. instlux allows you to
boot into the openSUSE installation right from a running Windows
by modifying the Windows boot loader. This installation option is only
available from the DVD media. Refer to
Section 1.2.3, Installing with instlux from Windows for details.
openSUSE supports several different boot options from which you can
choose depending on the hardware available and on the installation
scenario you prefer. Booting from the openSUSE media or using
instlux are the most straightforward options, but special requirements
might call for special setups:
Table 1-1 Boot Options
|
DVD/CD-ROM
|
This is the easiest boot option. This option can be used if the
system has a local CD-ROM drive that is supported by Linux.
|
|
instlux
|
instlux is installed under Microsoft Windows* and makes it possible
to boot directly into the installation
|
|
Floppy
|
The data for generating boot floppies are located on DVD 1 in the
/boot/architecture/
directory. A README with instructions on how to
create the boot floppies is available in the same directory.
|
|
PXE or BOOTP
|
Booting over the network must be supported by the system's BIOS or
firmware and a boot server must be available in the network. This
task can also be handled by another openSUSE system.
See
https://en.opensuse.org/SuSE_install_with_PXE_boot
for more information.Refer to
Section 1.0, Remote Installation, (↑ Reference ) for more
information.
|
|
Hard Disk
|
openSUSE installation can also be booted from the hard disk. To
do this, copy the kernel (linux) and the
installation system (initrd) from the
directory
/boot/architecture/loader
on the installation media to the hard disk and add an appropriate
entry to the existing boot loader of a previous openSUSE
installation.

1.2.1 Installing from a Network Server Using SLP
If your network setup supports OpenSLP and your network installation
source has been configured to announce itself via SLP (described in
Section 1.2, Setting Up the Server Holding the Installation Sources, (↑ Reference )), boot the
system, press F4 in the boot screen and select
from the menu.
The installation program configures the network connection with DHCP and
retrieves the location of the network installation source from the
OpenSLP server. If the automatic DHCP network configuration fails, you
are prompted to enter the appropriate parameters manually. The
installation then proceeds as described below with the exception of the
network configuration step needed prior to adding additional
repositories. This step is not needed as the network is already
configured and active at this point.
1.2.2 Installing from a Network Source without SLP
If your network setup does not support OpenSLP for the retrieval of
network installation sources, boot the system and press
F4 in the boot screen to select the desired
network protocol (NFS, HTTP, FTP, or SMB/CIFS). Provide the server's
address and the path to the installation media.
The installation program automatically configures the network connection
with DHCP. If this configuration fails, you are prompted to enter the
appropriate parameters manually. The installation retrieves the
installation data from the source specified. The installation then
proceeds as described below with the exception of the network
configuration step needed prior to adding additional repositories. This
step is not needed as the network is already configured and active at
this point.
1.2.3 Installing with instlux from Windows
instlux is a Microsoft Windows* application that
prepares your computer to directly boot into the openSUSE
installation without having to adjust BIOS settings. instlux is only
available on DVD media. To use instlux, insert the openSUSE media
under Windows. The openSUSE 11.1
Installer setup automatically starts. Choose a
language for the installation and follow the instructions on the screen.
The language you choose here is also preconfigured to be used for the
openSUSE installation.
On the next reboot, the Microsoft Windows boot loader launches. Choose
openSUSE 11.1 to start the
openSUSE installation. In order to proceed with the installation,
you will be prompted to insert the installation media. The installation
proceeds as described below. When Microsoft Windows is booted again,
instlux is automatically uninstalled.
HINT: Installing openSUSE alongside Microsoft Windows
openSUSE can easily be installed alongside Microsoft Windows. Carry
out the installation as described below—an existing Windows
installation will automatically be detected and a dual boot option will
be installed. If Windows covers the whole installation disk, the
installation routine will make a reasonable proposal to shrink an
existing Windows partition in order to make room for the openSUSE.
Please read
Resizing a Windows Partition prior
to the installation for detailed information.
