shame konnichiwa, if you want my advice, the windows installers aren't great, and I'd go for a CD install every time. Although burning can be difficult, luckily for you, canonical will mail you CDs free of charge.
https://shipit.ubuntu.com/
Just visit that site, give em your name and address, and they'll ship you as many ubuntu CDs as you want. It's a fantastic service, get 10 cds and give them out to your mates. You'll have to wait for delivery, but since you seem to be having a few issues with burning a CD, this might be the easiest option.
Help! I'm stuck in a forum signature!
