Prebuilt distributions part 3

[This is the final article in a three part series. Read part 1 and part 2.]
In this part I was going to discuss the different installation options, and I’ll give a quick introduction to each at the end. But you know? What I really need is this tool:

Prebuilt distributions part 2

In part 1 I discussed how these days Linux Live CDs usually come with a prebuilt disk image of the distro which is simply copied over to the hard disk during installation.
