I've been using Windows for 18 years and am finally sick of it, so want to try ubuntu. 

I have followed the installation instructions on the official ubuntu sites but can't make any progress. My computer does not have a cd drive (slimline laptop) so i followed the instructions to download to a live USB and also directly onto a partition using windows installer. 

When the downloads are complete nothing else happens, but the file "ubuntu-12.10-desktop-i386" can be found through explorer. Double clicking on this file opens a dialogue box called "Windows disc image burner" which gives the message "a disc burner wasn't found". 

And that's it! Nothing else happens. I've tried downloading ubuntu direct to a partition and the 'live usb' trial from Ubuntu and Ubuntu mint but get the same result. Nothing shows on the boot manager either...

Am i doing something wrong? Can anyone help?!
