In this video, learn how to install Ubuntu 10.04 LTS without making any permanent changes to your partitions on your hard drive by using Oracle Virtual Box to emulate Ubuntu within Windows and other host Operating systems like Apple/Mac, or another Linux distro.
I will teach you step by step on how to install Ubuntu, and install VirtualBox guest additions for improve desktop performance on to your virtual machine. I will also show you how to change the background and themes on your Ubuntu desktop.
I’ll also show you how to install Adobe Flash Player on to Ubuntu with Ubuntu Software Center, so you can watch Youtube videos in Ubuntu Linux.
The advantages of using a virtualization software like Virtual Box, Vmware, Virtual PC, Qemu, etc is that it is 100% safe, and you won’t risk losing your files because you messed up your partitions or you installed Ubuntu on the wrong partition and accidental installed it on your Windows partition. Virtual Box OS  files are also very easy to back up all you do is copy your hard drive files to an external drive. It is also very easy to delete Ubuntu from your Virtual Box Hard drive, so if you do not like Ubuntu , all you have to do is right click the Virtual box hard drive for Ubuntu and click delete.
The disadvantage of using Virtual Box is it is slower then running Ubuntu on a dedicated hard drive, and some of the 3D and graphics capabilities don’t work on Ubuntu. If your host operating system is broken, then you can’t use Ubuntu in Virtual Box. It is also very easy to delete a Virtual Box hard drive, so if you accidental delete it., your entire Ubuntu OS is gone.
Recently, I got a USB TV tuner which prevented my computer from recognizing my USB memory card reader. In device manager there was also an “Unknown device” with a yellow triangle icon with an exclamation mark in the middle, and every time my PC woke from sleep or hibernate there was a warning message on the bottom right of the system tray on the Windows desktop taskbar.Â
It was kind of frustrating to fix, but, it was extremely simple to fix my problem of my USB TV tuner blocking my card reader from working.
Stuff I did to try to fix my USB conflict problem
I thought it might be Windows Update messing up my Card reader by installing a Card Reader driver which I don’t need because my card reader just used the generic USB drivers and drive drivers for Windows 7. When I used Vista, Windows Update installed some card reader software for some brand of card reader which I do not even own which was very strange.
I looked through my Windows Updates and uninstall program list in Windows 7, and I see nothing related to a SD card reader was installed recently.
The only thing that work was unplugging my USB TV tuner, and waiting until start up was complete, and then plug in my TV tuner. But, I don’t consider that a solution since I use my TV tuner and SD card reader  everyday, so if I forgot to plug in my USB TV tuner. I can’t record shows which I set to record when I’m not at my PC. If I forgot to unplug my TV tuner before I started up my computer, then my SD memory card reader will not work, so I need to unplug my TV tuner and reboot my PC which is time consuming and frustrating.Â
I tried installing the newest drivers, and uninstalling my old drivers. But, it did not work. I tried restarting my PC as well which did not work. I also tried the driver cleaner uninstaller for my USB TV tuner which also did not work.

In this video, I will teach you how to start your computer from Ubuntu 10.04 LTS live install CD. All you have to do is configure your BIOS CMOS or Boot loader to tell your computer to boot from a Optical disc like CD or DVD instead of a floppy or hard drive first. You need to press F11, Del, esc, or some other key depending on your brand of computer or motherboard. Press the pause button on the keyboard immediately after you press the power switch on your computer to pause the start up process since there is usually a text start up screen which is black and white where there are labels on the screen to tell you which buttons to press to enter the BIOS or boot loader.
