I'm in the process of installing Xubuntu 12.04 on an older laptop, a Dell Inspiron 700m with Windows XP. I know there are potential issues with the graphics card so I want to try before I install.

After I select my language, my menu choices are:
  • install Xubuntu
  • check disc for defects (which I did, no problems)
  • test memory
  • boot from first hard drive disk
  • rescue a broken system

Rather than install yet (and since there is no "try" option), I boot to XP, but there is no desktop icon to try Xubuntu. Indeed, I cannot figure out how to get the DVD to run from Windows.

How do I try without installing?
