Prepare to install Ubuntu Linux. Before you can install Ubuntu Linux, you'll need to prepare a few things. First, you'll need a Ununtu Linux CD or DVD. You could order the CD through the ShipIt service, available from the URL shown here, but as CDs are shipped from Europe from the least expensive available mail service, that process can take several weeks, but hey, the price is right. If you can't wait those several weeks and have a high-speed Internet connection, download the CD or DVD as suggested earlier in the system requirements video. But there are several different types of CDs and DVDs available. Three options are most suitable for the installation of Ubuntu Linux. The Live CD allows you to install Ubuntu Linux from a live system, in other words, you have a complete version of Ubuntu Linux loaded directly from the CD or DVD drive. The GUI installation program is accessible from the live CD or live DVD. While you're supposed to have at least 380 megabytes of RAM to run the live CD, I've done it with less, 256 megabytes of RAM is typically sufficient for me. The alternate CD does not include a live version of Ubuntu Linux, but it does allow access to the text mode installation program. The DVD includes features of both, in other words, it supports the loading of a live Ubuntu system form the DVD media and access to the GUI installation program, it also allows access to the text mode installation program. All of these images can be downloaded as ISO files, typically with .iso extensions. Just be aware, these files are typically as big as the CD or DVD media for which they're intended. In other words, if you're going to download a Ubuntu installation CD, be prepared to download about 700 megabytes of data. For a DVD, be ready to download over 4 gigabytes of data. There are other variants on installation, such as Ubuntu server, which we'll discuss in another video. Once you've selected and downloaded a installation ISO image, you can burn that image from the .iso file direct to a physical CD or DVD using a suitable program. Linux is filled with suitable programs for this purpose from the Command Line or from the GUI such as Nautilus or K3B, but since the ISO standard is pretty universal, you can even burn those files to CDs or DVDs using applications available on Microsoft Windows. But, you may not even need to burn the ISO file. If you use a virtual machine such as VMware, you can mount the ISO file directly as if it were a CD or DVD. That's what I do on a VMware server system, I specify 256 megabytes of RAM, and in my case, an 8 gigabyte hard drive, as shown here. I can then boot directly from the CD/DVD drive to get to the Boot menu, shown here.
