try slax (linux live cd) , if the LG is your only burner then i suggest youll goto a friend and get it downloaded & burned from there , or workplace
if you have a single core processor,use version 18.104.22.168 and if dual core use 6.0 pre 10 , links for both:
naturally youll need to set the optical drive first in bios boot order , now what you should do after booting the cd (its not automated..) , first youll be asked for account user/password this is hardcoded and its root/toor , if your running slax from another optical drive leaving your LG burner free then type startx and hit enter this will run KDE (graphical user interface) , if the LG is the only optical drive you have and you have at least 384mb of ram then you can load it to ram leaving your drive free after it finishes loading , to do that put these commands one after another and hit enter after each (after you inputed the user/password of course)
youll get along from there the GUI is quite easy to handle,btw the burnning software thats integrated in slax is called k3b i think , anyway if its not looking good on slax either then your burner is likely faulty and youll need to have it replaced , however if its all good there then its something with your vista (and i have no idea what) so it will be a good idea to format & reinstall..
edit btw the first button down on the left (blue K) ,is kinda like the windows start button..
