Ubuntu Linux 12.04 LTS is a great operating system which can be start from a CD, USB drive, and can be installed on a hard drive. I like that it can be run from most older computers since the minimum requirements are low if your computer can run Windows Vista, or have a 1GHz CPU, 1GB of RAM, 10GB of hard drive space, and a video card, you can run Ubuntu pretty well.
You can try Ubuntu 12.04 LTS on a HP a1720n desktop out by starting it from a USB flash drive which you plug into your computer before turning on your computer by clicking ESC to launch its built-in start up manager. When the start-up manager loaded. To select your USB flash drive, use the up and down arrow keys on your keyboard, and press the enter key to start Ubuntu from the USB flash drive. When Ubuntu have loaded, you can pick Try Ubuntu or Install Ubuntu. I recommend trying Ubuntu before you install to see if everything works before installing. It also gives you a chance to back up your data on your hard drive before installing just in case you experience data lost during the install.
The Patriot Xporter XT Boost USB Drive was used for this tutorial because it is a fast, durable and reliable USB 2.0 flash drive which makes Ubuntu run faster on a flash drive because of faster Read speeds then lower quality USB 1.1-2.0 flash drives.
Short Review of Ubuntu Linux 12.04 LTS
Ubuntu 12.04 LTS was pretty easy to install on my computer since the installer is step by step visual based, so I just follow the instructions the installer gives me like set my time zone, making an account, and which drive or partition to install Ubuntu on to. It took about an hour to install Ubuntu 12.04 LTS, and less then an hour to fully update Ubuntu by checking for Updates with the Update manager via the internet.
My sound, video, internet, mouse, keyboard, and USB flash drives all work after Ubuntu Linux is fully installed on my computer.
Installing programs like Chromium web browser, Adobe Flash player, Gimp, and other programs are simple with the Ubuntu software center.
I like that the search engine on the top right of Ubuntu now can be used to search for online videos, and to launch shortcuts in programs like Gimp.
The sidebar dock is now resizeable, and can be pinned to the left of the screen, so it does not autohide which is useful for people who multi-task a lot.
Ubuntu also has been very stable for me since it rarely crashes when I’m using Chromium web browser, Smplayer, and other programs.
Ubuntu Linux also starts up in under a minute, and shut down very fast in a few seconds.
The best part of Ubuntu Linux is that I do not have to run disk defrag, disk cleanup, and disk scans on a regular basis because Ubuntu does not slow down after time in my experience. Web browsers also use less RAM, and CPU cycles compared to Windows in my experience.
It is also free to download and use Ubuntu Linux 12.04 LTS on your computer, laptop, and server, so the cost savings for Ubuntu Linux 12.04 LTS can be huge if you install it on a lot of computer since you won’t need to buy an operating system to go online.
