I'd like to install Ubuntu server on my machine, is there a step-by-step instructions on how to accomplish that or a guide that will just go through the basic steps of installing Ubuntu Server from beginning to end.
Instructions originally for 13.04.
First, you will need to download the current version of Ubuntu Server. A 64 bit version is recommended, but you can also download a 32bit version from http://releases.ubuntu.com/. Once downloaded you need to create a bootable CD/DVD or USB flash.

Once done, put the disc in your drive, or insert the USB flash, and reboot your machine. Make sure that you set your BIOS to boot either from the CD/DVD or USB flash depending on which installation method you choose.

You're done. Reboot your machine, and type in your username you created earlier, and your password to login. That is it, you are now logged in to your new Ubuntu server!
Some more details about the other options in the first Step.
First, this menu also offers you an option to Check disc for defects. Although I'm sure you've done well in creating your media, all it takes is for a small corruption in the download or with the dd command and you would end up with invalid media. This is extremely rare—but it does happen from time to time. If you have the extra time, it may make sense to verify your media.
This menu gives you the option to Test memory. This is an option I've found myself using far more often than I'd like to admit. Defective RAM on computers and servers is surprisingly common and can cause all kinds of strange things to happen. For one, defective RAM may cause your installation to fail. Worse, your installation could also succeed—and I say that's worse due to the fact you'd find out about problems later rather than right away. While doing a memory test can add considerable time to the installation process, I definitely recommend it, especially if the hardware is new and hasn't ever been tested at all. In fact, I make it a process to test the RAM of all my servers once or twice a year, so this media can be used as a memory tester any time you need one.
The Rescue a broken systemThe Rescue a broken system option is also useful to recover systems that, for some reason, are unable to boot at all.
