Install via a CD-ROM or a USB Key
For clients that are not yet registered to SUSE Manager, and if network boot over PXE is not an option, a bootable CD-ROM or USB key can be used to install the system.
One option to prepare such a removable medium is to use Cobbler. For information about using Cobbler to prepare an ISO image, see Build an ISO Image With Cobbler.
The other option is to use mechanisms specific to the distribution:
In all cases, you use the resulting image to burn a CD-ROM or prepare a USB key.
Cobbler can create ISO boot images that contain a set of distributions, kernels, and a menu that works in a similar way to a PXE installation.
Building ISOs with Cobbler is not supported on IBM Z.
In order to prepare an ISO image with Cobbler, you need to prepare a distribution and a profile, similar to using network boot over PXE. For information about creating a distribution, see Autoinstallable Distributions. For information about creating a profile, see Autoinstallation Profiles.
buildiso command takes parameters to define the name and output location of the boot ISO.
cobbler buildiso --iso=/path/to/boot.iso
The boot ISO includes all profiles and systems by default.
You can limit which profiles and systems are used with the
cobbler buildiso --systems="system1 system2 system3" \ --profiles="profile1 profile2 profile3"
If you cannot write an ISO image to a public
KIWI is an image creation system. You can use KIWI to create a bootable ISO image to be used by the target system for installation of a SUSE system. When the system is rebooted or switched on, it boots from the image, loads the AutoYaST configuration from your SUSE Manager, and installs SUSE Linux Enterprise Server according to the AutoYaST profile.
To use the ISO image, boot the system and type
autoyast at the prompt (assuming you left the label for the AutoYaST boot as
Press Enter to begin the AutoYaST installation.

You can use
mkisofs to create a bootable ISO image to be used by the target system for installation of a Red Hat system.
When the system is rebooted or switched on, it boots from the image, loads the Kickstart configuration from your SUSE Manager, and installs Red Hat Enterprise Linux according to the Kickstart profile.
Copy the contents of
/isolinuxfrom the first CD-ROM of the target distribution.
isolinux.cfgfile to default to 'ks'. Change the 'ks' section to read:
label ks kernel vmlinuz append text ks=`url` initrd=initrd.img lang= devfs=nomount \ ramdisk_size=16438 `ksdevice`
IP address-based Kickstart URLs look like this:
The Kickstart distribution defined via the IP range should match the distribution from which you are building, to prevent errors occurring.
OPTIONAL: If you want to use the
ksdevice, it looks like this:
It is possible to change the distribution for a Kickstart profile within a family, such as Red Hat Enterprise Linux AS 4 to Red Hat Enterprise Linux ES 4, by specifying the new distribution label. Note that you cannot move between versions (4 to 5) or between updates (U1 to U2).
isolinux.cfgfurther as required. For example, you can add multiple options, different boot messages, or shorter timeout periods.
Create the ISO with this command:
mkisofs -o file.iso -b isolinux.bin -c boot.cat -no-emul-boot \ -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/
isolinux/is the relative path to the directory containing the modified isolinux files copied from the distribution CD, while
file.isois the output ISO file, which is placed into the current directory.
Burn the ISO to CD-ROM and insert the disk. Alternatively prepare an USB key and insert it.
Boot the system and type
ksat the prompt (if you left the label for the Kickstart boot as 'ks').
Press Enter to start Kickstart.
