How can I upgrade From 2.8 to 3.0

I have not downloaded and tested LL 3.0 yet, so not sure what is the cause of problem.  Following is just a shot-in-the-dark guess as to what might be causing the problem.  Every once in a while, on certain computers (mostly older ones) the slideshow program that runs during installation causes problems similar to what you're describing.  The solution in those cases was to remove the slideshow package before running the installer.  You might as well give that a try just in case that is causing your issue.

• Boot LL 3.0 live dvd/usb
  
• Open Menu -> System -> Install/Remove Software (which is the Synaptic Package Manager)
  
• Click the Search box and search for ubiquity-slideshow
  
• It should return showing that ubiquity-slideshow-ubuntu (or similar name) is installed -- indicated by green box next to the name.
  
• Click green box next to name and choose Mark for removal
  
• Hit the Apply button along top of interface to carry out the removal operation
  
• Close Synaptic when done.
  
• Now you can run the installer and hopefully it finishes the install correctly.
  

If that doesn't solve problem, then most likely this is the problem:

If your hardware architecture is only 32bit, perhaps it is old enough that when advancing to a distribution with a newer kernel, your hardware ends up being unsupported.  As kernels get newer, they drop support for some older hardware.
