Multiboot

[chuck]

I do not have a DVD burner. I just double clicked the .iso file in Vista and 
the burning software launched. I goes through its motions and then tells me 
it cannot put 702 mb on a 700 mb cd.
As I stated earlier, I have downloaded and installed magiciso, a virtual cd 
rom emulator, that allows mounting the ISO as if it were a cd in a real 
cd-rom. My question, can I run the Ubuntu install from Vista, or mist I burn 
the .iso to a real cd and boot from it?
