## 2.2. Installation Media

This section will help you determine which different media types you can use to install Ubuntu. There is a whole chapter devoted to media, Chapter 4, Obtaining System Installation Media, which lists the advantages and disadvantages of each media type. You may want to refer back to this page once you reach that section.

### 2.2.1. Network

The network can be used during the installation to retrieve files needed for the installation. Whether the network is used or not depends on the installation method you choose and your answers to certain questions that will be asked during the installation. The installation system supports most types of network connections (including PPPoE, but not ISDN or PPP), via either HTTP or FTP. After the installation is completed, you can also configure your system to use ISDN and PPP.

### 2.2.2. Hard Disk

Booting the installation system directly from a hard disk is another option for many architectures. This will require some other operating system to load the installer onto the hard disk. This method is only recommended for special cases when no other installation method is available.

### 2.2.3. Un*x or GNU system

If you are running another Unix-like system, you could use it to install Ubuntu without using the `debian-installer` described in the rest of this manual. This kind of install may be useful for users with otherwise unsupported hardware or on hosts which can't afford downtime. If you are interested in this technique, skip to the Section D.4, “Installing Ubuntu from a Unix/Linux System”. This installation method is only recommended for advanced users when no other installation method is available.

### 2.2.4. Supported Storage Systems

The Ubuntu installer contains a kernel which is built to maximize the number of systems it runs on.

Any storage system supported by the Linux kernel is also supported by the boot system. This means that FBA and ECKD DASDs are supported with the old Linux disk layout (ldl) and the new common S/390 disk layout (cdl).
