Do you have a USB drive at least 2GB in capacity? then you do not need to burn a dvd to test or install Ubuntu Reloaded!
visit http://unetbootin.sourceforge.net/
download unetbootin for whatever platform you are on, and make a bootable usb.It is too easy...
Now its time to boot from your bootable pen drive...
a) Insert the usb drive before you power on your computer.
b) enter bios by pressing F1 or Del or F12 or whatever is applicable according to your motherboard.
c) go into advanced section of bios and look for boot order priority.
d) go into hard disk order and see whether your USB drive is being displayed...make it first.
e) press F10 to save and exit.
this time your computer will boot from USB drive (if you earlier booted from your hard drive).press enter when you are shown boot prompt.
note: on some motherboards it might show 'boot failure'. you can try with another USB drive or try your own USB drive on some other computer.
if you are on ubuntu you can use the inbuilt usb startupdisk creator.
